  3. 3. Some reasons to discuss these topics with Fujitsu Fujitsu has a very long history in the topic of server virtualization – more than 40 years. It started with virtual machines in our mainframe offering, GlobalServer and Fujitsu’s BS2000, which still are available. Knowing the technology and its benefits from the beginning, Fujitsu has also completed thousands of x86 server virtualization projects successfully. Fujitsu also transferred its experience as one of the world’s leading cloud service providers in helping customers to build their cloud environment. This is proven by many current success stories and Fujitsu’s contributions in Microsoft Private Cloud Fast Track and the Intel Cloud Builder Program. Fujitsu’s products, such as PRIMERGY x86 servers and ETERNUS storage systems, are all optimized for x86 server virtualization and cloud infrastructure scenarios – by using the latest technologies, with special features and maximum compatibility with market standards – as proven by many benchmark records. In this context it is also worth mentioning the integration of server virtualization with Fujitsu solutions and Fujitsu’s offerings that extend virtualization. One example of the use of server virtualization within complete solutions is Fujitsu FlexFrame for SAP. Fujitsu ServerView Resource Orchestrator and Fujitsu DI Blocks are examples of an extended server virtualization offering. Both allow the uniform management of a mixed environment – even if different server virtualization technologies are used or if it is a mix of virtual machines and physical servers. Moreover, Fujitsu DI Blocks are a preconfigured complete IT infrastructure, which besides its very short time-to-production, also includes the entire lifecycle management – a full worry-free package. Not to forget Fujitsu’s data protection appliance ETERNUS CS, harmonizing and optimizing entire backup and archiving scenarios. A further essential argument why you should deal with Fujitsu in the area of server virtualization and cloud computing is Fujitsu’s complete service offering. This service offering for all aspects of server virtualization and including any kind of cloud services starts with pre-defined and fixed price assessment services to analyze the current customer situation and to provide customers with re­ ommendations about how to proceed with their IT. Among c others, these OPTIMIZATION Services are available for cloud computing and server virtualization. Beside these consulting services, ROI/ TCO estimations, design services, delivery services, operation services, product/solution-related services, various managed services and financial services are also available. Fujitsu’s close cooperation with all market leaders in virtualization and cloud technologies puts us into a position to be the trusted advisor of our customers. For some similar technologies we deal with different partners – for example on the server virtualization layer with Citrix, Microsoft, SuSe, Oracle, RedHat and VMware – in order to have an appropriate solution for any customer requirement. Even the broad storage portfolio of Fujitsu’s self-developed ETERNUS systems is extended by our close cooperation with NetApp. Moreover, it should be mentioned that Fujitsu is the only server manu­ facturer today that develops and produces its x86 PRIMERGY servers in the heart of Europe. One further argument, especially for global customers, is Fujitsu’s capability to serve customers worldwide with all levels of expertise, products and services. Our follow-the-sun call centers support more than 25 languages. Page 3 of 42
  4. 4. Insights Server Virtualization and Private Clouds x86 server virtualization What is virtualization? Within the IT industry virtualization is used between today’s interfaces to abstract different layers from each other. Because of defined and comprehensive interfaces the dependencies of different IT ‘layers’ (e.g. the server hardware and the connected network infrastructure) are very strong and often result in inflexibility and low utilization. For example: When one layer is updated, the other one needs an update, too. When one layer is defined, the upper and lower layer often can’t be used for anything else. To overcome these strong dependencies an additional layer – the virtualization layer – can be inserted. As today’s IT has many defined layers, the possibility of inserting separation layers between them is also varied. Just to name some of the resulting virtualization technologies: ■■ I/O virtualization ■■ Server virtualization ■■ Network virtualization ■■ Application virtualization ■■ Storage virtualization ■■ Client virtualization ■■ Operating system virtualization ■■ ... Many IT installations during the past years often contained more than one of these technologies in order to combine their related benefits and to achieve a state-of-the-art, dynamic IT infrastructure. In terms of this document we are focusing on x86 server virtualization. What is x86 server virtualization? As the title indicates, x86 server virtualization describes the virtualization layer between x86 architecture-based server hardware and the associated operating system. This virtualization layer is usually called the hypervisor. This hypervisor isolates the x86 server hardware from the various operating systems. The server hardware sees it as its operating system and provides the known operating systems with the capability to use pre-defined portions of the available x86 hardware resources. Those portions are called virtual machines (VMs) and are fully isolated from each other. They do not even know each other. This enables the sharing of server-hardware capabilities between different operating systems and applications. The core tasks of a hypervisor are: ■■ Foundation to operate VMs ■■ Separation of the VMs from each other ■■ fficient distribution of resources between VMs E in line with the administrator’s specifications ■■ Mapping of machine instructions issued in a VM ■■ Mapping of I/O jobs The indirect advantage of a virtualization layer By adding an additional layer as an interface between the server hardware and the operating system, a further major advantage can be achieved: it is possible to influence their communication. Said influence never means modifying anything, but it enables time shifting and – even more important – sharing of information. Transferred to server virtualization this means that memory and CPU states of a virtual machine can be copied to another server. The result is one major feature of using hypervisors: ■■ ive Migration (aka as VMotion, XenMotion, …) of virtual maL chines (including operating system and application) without any interruption from one server to another one This is the fundamental technology used for many further automation features provided within hypervisor management. Page 4 of 42 http://reshaping-datacenter.ts.fujitsu.com/
  5. 5. Preconditions to the effective use of server virtualization In addition to the very obvious components of a virtualized infrastructure: hypervisor, its management and appropriate x86 server hardware (optimized server virtualization support, fitting I/O connections) centrally accessible storage is also an elementary component. To make use of the high availability options – e.g. restart of a virtual machine in case of a hardware failure on a different server – the server inevitably needs access to the data of that virtual machine where it should be restarted. So typically storage consolidation has to be done first, before x86 server virtualization is introduced/expanded to leverage all the capabilities provided by this technology. How to manage hypervisors? As can be imagined, the hypervisor itself has to be a lean and very efficient piece of software. Therefore, to provide little or no surface for security attacks the hypervisor itself is optimized to support its basic functions and to move all resource-intensive tasks (e.g. management via GUI, automatism, rules, …) to outside management software. This management software takes care of the entire management of the hypervisor AND the virtual machines. It allows comprehensive management of the hypervisor and virtual machine capabilities. Every hypervisor vendor provides its own management software, which partly is also able to manage hypervisors/virtual machines from other vendors. But usually you get the best results and access to the full set of features if the management software of the hypervisor vendor is used. To have an indication of pure hypervisor size it should be noted that for example vSphere ESXi from the market leader VMware has a size of approximately 50 MB. Format of virtual machines Due to the fact that the variable hypervisors are based on technically different sources, a virtual machine generated for one specific hypervisor would not be able to be operated on the hypervisor of another vendor. To overcome this problem and to enable appliances (the application ships as part of the virtual machine and not in conventional installation format) all major hypervisor vendors support the OVF (Open Virtualization Format). By using this format the respective virtual machine can be executed on different hypervisors without any changes. However, by using this format (standardized by Distributed Management Task Force, Inc. – short DMTF) some specific features provided by just one vendor probably can’t be leveraged for the VM in OVF because it is standardized. In the past and also likely in the future this results for some customers in the need to operate more than one hypervisor type in their data center. Performance impact of the hypervisor Inserting an additional layer often gives the impression that everything gets complicated and more power is needed. This partly applies also for x86 server virtualization, BUT ■■ 86 servers have had a tremendous performance boost for x many years, which is still continuous ■■ he average utilization rate of x86 servers without using T server virtualization is usually below 15% ■■ oday’s x86 servers and their used components are optimized T for server virtualization ■■ early all hypervisors are stable and performance-optimized – N in various ways This results in the overall message that the typical performance impact of much less than 10%, if real-time operating systems are not used, can be disregarded.

  6. 6. Insights Server Virtualization and Private Clouds Benefits of server virtualization Customers can achieve many business benefits by using server virtualization. The technology in principal might not be new, but it has never paid off on such large scale. First, for most implementers the achievable consolidation ratio was the key motivation to introduce server virtualization within their company. When customers are able to replace 10 (or even more) old servers with one new server that additionally needs less power than one of the old servers, this results in tremendous savings in investment costs (CAPEX) and operating cost (OPEX – energy, space requirement and management). Additionally, the homogenous virtualization layer allows customers to run old operating systems on new hardware. The example often used is Windows NT, which is already out of any Microsoft support and certification program and which is executed in a virtual machine running on the up-to-date Fujitsu PRIMERGY generation. Any virtual machine can also be implemented on any ‘virtualized’ server hardware, which provides very flexible use of all x86 resources. Not to forget the very easy scalability. As mentioned above, there are many options to lower the number of powered-on servers. The opposite, e.g. extending a virtualized environment, just needs an additional server with the appropriate hypervisor. Just connect the server to the network and it can be integrated in the overall environment with a few mouse clicks. All of that is complemented by the integrated and uniform high availability concept that comes with using server virtualization. In the past it was often very complicated to set up high availability solutions, because many of them had application or operating-system-specific dependencies and were mostly associated with an additional license fee. By using server virtualization all hypervisor vendors enable an integrated, application and operating-system-independent concept: if a server fails or can’t be contacted, all virtual machines can – depending on the predefined settings – automatically be restarted on another server. This is uniform for the complete virtualized environment. On top of this, you can add mechanisms which control the applications to extend this general capability to an application-aware feature. To avoid misunderstandings: traditional clusters still work when server virtualization is used. Many automation functions could be implemented with the option of live migration of workloads from one server to another. For example, power-optimized use of servers while all applications are up and running: if the applications are only rarely used, they can be aggregated on a few servers and the remaining servers could be switched off. When more compute performance is needed, an appropriate number of switched-off servers would be powered-on and the applications in the virtual machines would be live-migrated to the powered-on servers – all of that fully automatically and without any interruption of the application. Similar things apply for hardware maintenance windows: zero downtime. Can everything be virtualized? Unfortunately not everything can be virtualized with server virtualization. All servers produced today include virtualization-optimized features. But servers bought more than 4 years ago probably do not support all capabilities of a hypervisor and its management. Also certain I/O cards (e.g. dongles, fax cards, special graphic cards, ...) can’t be used with x86 server virtualization. Which components are supported can be seen in the hardware compatibility list (HCL) of the various hypervisor vendors. The number of unsupported and currently available components is getting smaller and smaller. Software deployments also get much easier: a virtual machine does not need to be ‘active’ – the management of the hypervisor can also update offline machines. Likewise all hypervisor vendors provide convenient tools to run automatic updates of all affected machines or duplicate existing virtual machines or templates. A new service can be up and running with just a few mouse clicks. Market acceptance of server virtualization According to hypervisor vendors and many analysts more than 50% of all workloads of x86 servers are running in virtual machines since 2012. Moreover, also according to statements from IDC, Gartner and Forrester, the market share of Fujitsu’s hypervisor main partners, Citrix, Microsoft, SuSe, Oracle, RedHat and VMware, together is big- Page 6 of 42 http://reshaping-datacenter.ts.fujitsu.com/
  7. 7. customers to build their own cloud solutions. Moreover, they offer integrated tools for uncomplicated access to cloud services from own or publicly available offerings to also leverage the benefits of these cloud offerings. ger than 99% of all hypervisors used in business. The top three in the ranking with regard to the ‘number of virtual machines running on which hypervisors’ are: 1. VMware 2. Microsoft 3. Citrix Server virtualization and cloud computing The capabilities of server virtualization, especially its great benefits with regard to flexibility, uniform SLAs, automation options and scalability, can be perfectly used to deliver the foundation for cloud computing. This does not mean that any kind of cloud computing always relies on server virtualization, but it can be seen as one of the key enabling technologies for it. The picture from Gartner below describes the movement of customers from virtualization towards cloud computing and the logical steps in between. Any kind of cloud computing, whether private, hybrid or public clouds, is more than the extensive use of server virtualization. However, server virtualization is often one step towards cloud computing, which needs many more capabilities to be implemented. All hypervisor vendors work on their own cloud stacks to enable Server virtualization, what else? As already stated in previous sections, x86 server virtualization is a mature technology which naturally also expands its functions in associated areas. The main areas today are storage virtualization, network virtualization and cloud management. With cloud management all kinds of cloud computing: private, hybrid and public clouds are addressed. Overall this development results in many nice features, formerly known from separate tools and vendors only, can easily be accessed by additional licensing options of the server virtualization layer and its managment. Meanwhile all hypervisor vendors have an offering beyond pure server virtualization and these offerings merge together. This also applies for Fujitsu with offerings that extend virtualization described in further sections of this document.

  8. 8. Insights Server Virtualization and Private Clouds Private Clouds What is ‘cloud’? Fujitsu defines ‘cloud’ as the consumption of infrastructure, an application, an activity or content of which that consumption comprises three distinct attributes: ■■ Pay per use ■■ Elastic and scalable ■■ Self service Clouds are usually available in four different formats: ■■ Private Cloud is dedicated for one customer. ■■ Community or Trusted cloud is for serving a number of selected customers. ■■ Public cloud is for (theoretically) every customer. ■■ Hybrid cloud is any combination of the three others. Each format could provide services with the three distinct attributes. The most popular services today are: ■■ aaS, Infrastructure-as-a-Service: providing server, storage and/or I network capacities to its users (e.g. system administrator) ■■ aaS, Platform-as-a-Service: providing operating systems P and software development tools including the necessary IT infrastructure to its users (e.g. software developer) – mostly used to provide (not use) SaaS later on ■■ aaS, Software-as-a-Service: providing the ability to use software S to its users (e.g. any user knowing the software) ■■ PaaS, Business-Processes-as-a-Service: providing the use of B complete business processes to its users (e.g. logistics manager) Cloud: Consuming IT as a Utility Pay per use Elastically Scalable Private just for you Self Service Community selectively shared Public shared with anyone Hybrid – a combination IaaS PaaS SaaS From the user perspective, the technology and the ‘how to’ issues usually associated when a new service is needed are completely taken away. Users of cloud services can fully concentrate on their core business and do not have to deal with daily operations because of the standardized and automated processes coming along with cloud computing. Just to give you an example: by using the cloud – independent of whether this a private, public, community or hybrid cloud, but depending on the service offered, see examples above – a catalog with predefined services is the starting point. Access is realized via a self-service portal where the user can apply for the requested service. After the user has found its appropriate service and applied for it, an acceptance/rejection workflow runs automatically. If the request is accepted, the user can access the service according to the description of the catalog. In addition to the functional description of the service, the aforementioned service catalog also contains information on the pricing (based on use time), term and time of payments and the quality description of that service: like availability time a year, recovery time, frequency of backups (if any) and many more. Last mentioned examples are called Service Level Agreements, in short SLA. Summarized, the user of a cloud no longer has to take care of technology and how to set it up – the user can pick any available service, just use it when it is needed and only has to pay when the service has been used. What is Private Cloud? Private Cloud is a cloud environment that only serves one single customer. It is operated in two different ways: ■■ Private Cloud on-premises means the operation of your cloud in your data center with your IT infrastructure ■■ Private Cloud off-premises means the operation of a dedicated (again, just for you) as-a-service offering in the data center of your cloud provider As the cloud environment in both cases is dedicated to you and your needs, it is obvious that the key criteria for cloud computing – again: pay per use, elastic and scalable, self service – are difficult to match in full. For example, the benefits of ‘pay per use’, if you have a private cloud on-premises, might not be matched in full because you are still the owner of the entire IT infrastructure and there are investment and operation costs; more or less independent of how much capacity is used. On the other hand you have much better options to take influence on everything in that cloud, including the definition of SLAs and how to handle your data in detail. BPaaS In terms of this document, Private Cloud is Private Cloud on-premises. Page 8 of 42 http://reshaping-datacenter.ts.fujitsu.com/
  9. 9. Preparations for the effective use of Private Clouds Before transforming your IT infrastructure into a Private Cloud or setting it up from scratch, a detailed analysis of the business processes within your company has to be undertaken. This has to include how your individual short, mid and long-term targets can either be achieved by: ■■ xtended use of virtualization technologies and associated E automation tools ■■ Private Cloud environment on-premises ■■ Community or publicly available as-a-Service offerings Otherwise, you could possibly implement a Private Cloud environment and the achievements do not match your expectations. How to manage Private Clouds? The management of Private Clouds needs the same principle architecture as the management of any cloud. In general this is: The word ‘service’ in the picture above, which has already been mentioned several times, stands for that kind of service that should be provided by the Private Cloud to its users: infrastructure, platform, software or business processes. All management software components have to be integrated with each other to achieve a complete cloud solution. Today several tools are available for Private Cloud computing, e.g. Fujitsu ServerView Resource Orchestrator Cloud Edition, which is described in a separate section of this white paper. In addition and as already mentioned in the section on server virtualization, complete cloud management tools are available from hypervisor providers and also from management software companies. To have the optimal solution for our customers and their needs, we complement our portfolio with these solution stacks. Some of these tools, e.g. VMware vCloud Director, also allow managing resources from community or public cloud offerings – and thus lead to comprehensive management of your complete hybrid cloud environment. Benefits of Private Clouds The three distinct attributes of cloud computing already indicate the benefits of Private Cloud computing. In particular, these are: ■■ Ease of use ■■ Cost savings and cost transparency ■■ Very flexible use of IT resources Ease of use is achieved by the general structure of a cloud. The necessary and strict multi-tenancy (in Private Clouds these are often different departments of your company or probably each employee), the standardized service level (SLAs) and the self-service portal build the foundation to fit this benefit. It can be even improved by using further automation functions, well defined and prepared (e.g. SLAs) entries in the service catalog and by the provided services covering as much as possible of the tasks of each user, e.g. by providing Software-as-a Service instead of providing Infrastructure-as-a-Service for the respective user – depending on the needs of the user. Lower costs result from the shared infrastructure of a Private Cloud. For example, peak requirements of one department, often responsible for too many installed/assigned infrastructure components, can be absorbed by temporary assignment of free resources (e.g. compute power) when they are not needed by other users/departments. Thus, the average utilization rate is much better than before thanks to sharing the available resources between all users in a still separated (catchword ‘multi-tendency’) way. Moreover, the elements responsible for the ‘ease of use’ pay off again, because the users and administrators as well are freed from day-to-day routines and can focus on their key tasks. All of that is fully transparent through the metering and accounting functions of the cloud management layer and so avoids any fruitless discussions between departments when it comes to covering the IT costs. Generally, it could be said that as more services of a similar kind are provided by a Private Cloud the bigger the benefits are. But also the inclusion of public or community cloud services to your Private Cloud enhances the aforementioned benefits. Page 9 of 42
  10. 10. Insights Server Virtualization and Private Clouds Can everything be brought to the Private Cloud? Comparable to server virtualization, not every service or task can be operated in a Private Cloud. Again, depending on what kind of service should be provided, there might be major adoptions necessary. Let’s take Software-as-a-Service as an example. If you have the goal to provide SaaS for certain applications, these applications need some capabilities to be provided as-a-Service and also need the appropriate Private Cloud management stack. Operating the application without any adaptations or special management software in an IaaS environment would not provide the requested result. Beside technical issues license costs which blow your budget could also occur. Nevertheless, because Private Cloud environments are accepted in the market (see ‘Market acceptance of Private Clouds’) and also because nearly all established software providers and likewise many startups are extensively pushing this technology, the number of unsupported services is getting lower and lower. Performance impact of Private Clouds Obviously a Private Cloud needs an additional management layer, see section ‘How to manage Private Clouds?’ Most components of that management layer are not needed all the time – thus they only need small resources when they are executed. The always-on management software components, e.g. the metering tools, are optimized to have very little impact on daily operations. Today, the technology used to build the various Private Cloud services, whether it is IaaS, PaaS, SaaS or BPaaS, is different. This – combined with various management options – makes it very difficult to disclose exact figures on the performance impact. But the experience we gained with our own cloud service offerings and within our customer projects, where we supported our customers with the building of their Private Cloud, results in the overall message that the typical performance impact can be disregarded – mostly independent of what service is provided. Page 10 of 42 Market acceptance of Private Clouds According to various analysts Private Cloud computing will be used – at least for parts of their IT/business – by more than 40% of all enterprises. The clearly most popular service provided by Private Clouds is Infrastructure-as-a-Service; this also applies in productive use. The reason why IaaS is the most accepted service (again, within Private Clouds) is in the available offering for the required management stacks. The IaaS Private Cloud management stack is today the most complete and commercially available Private Cloud solution. As indicated in the comparable section of server virtualization, where VMware is the market leader, it is mainly used as the basis for IaaS services in Private Clouds. So it is no surprise that VMware is also the market leader in Private Cloud management stacks for IaaS. An ‘extended IaaS’ is often used to provide PaaS via Private Clouds. When it comes to SaaS, mainly application-specific solutions come into play nowadays. The same applies for BPaaS. One example of SaaS Private Cloud solutions is our FlexFrame for SAP, which is described in the section ‘SAP-aware IT infrastructure’. Summarized, it could be said that market acceptance for Private Clouds is high. Moreover, Infrastructure-as-a-Service is dominant today, but the other service offerings are evolving very strongly and especially SaaS will, when it has greater maturity and broader-based offerings are available, surpass IaaS in Private Cloud computing. Risks of Private Clouds Just as with benefits, which are in part difficult to achieve in full, the commonly discussed risks of cloud computing usually do not apply in full for Private Clouds on-premises. One of the main reasons holding back universal adoption of cloud computing is security. Being based on the Internet does make cloud computing susceptible to cyber attacks, but Private Clouds are operated within your firewalls and that makes them at least as secure as your infrastructure was before. When a company has its data in the cloud, it is not under its direct or physical control and due to the respective, applicable law other governments may have the right to view that data (e.g. in U.S. or with U.S.-based companies as cloud providers). However, Private Cloud on-premises hosts its storage capabilities in your data center, which is fully under your control. So you decide on the accessibility of your data and how it will be protected. We could extend this section by many other points but they key message would not change: most possible risks of public cloud computing are under your full control by running a Private Cloud environment. Therefore, the risk of your Private Cloud is your responsibility and depends on the SLAs you implement for your solution. http://reshaping-datacenter.ts.fujitsu.com/
  11. 11. Private Clouds and server virtualization Server virtualization is often used as the key technology in the area of Infrastructure-as-a-Service offerings in particular, but also for Platform-as-a-Service offerings. The described capabilities of server virtualization, enhanced with a serious Private Cloud management stack, are a validated combination that is often used today. It can also be said that the broad acceptance of server virtualization and its automation paved the way for cloud computing, especially with regard to IaaS. For the remaining cloud services server virtualization can be seen as enabling technology, but not as ‘must have’. SaaS and BPaaS can be built without using server virtualization, but you can also use IaaS as the enabler for SaaS, please take also a look at Fujitsu Cloud Store, described in the last section of this white paper. Private Clouds, what else? The natural extension of Private Cloud computing is its expansion to include cloud services from cloud service providers. This inclusion of other services is indicated several times in previous sections. For example, you can extend your compute power with Fujitsu’s Infrastructure-as-a-Service offering when you need more capacity than your Private Cloud can provide. Or you use our Backup-as-a-Service offering; originally developed to support SMBs to fulfill certain compliance regulations. The inclusion of public or community cloud offerings is the next step after having a Private Cloud on-premises implemented. Microsoft Private Cloud Fast Track This program initiated by our technology partner Microsoft describes in detail how exactly a Private Cloud infrastructure has to look to operate Microsoft applications best. Fujitsu, as one of the first five members, joined this initiative directly with its announcement in November 2010. According to the strict requirements of the program and with the claim to increase the value provided by reference architectures, we jointly defined our reference architecture with Microsoft. Fujitsu’s configuations, except the special versions for SMBs, consist of Fujitsu PRIMERGY Servers, Fujitsu ETERNUS Storage, Fujitsu ServerView Suite, network components and the Microsoft management software stack. Intel Cloud Builder As opposed to Microsoft Private Cloud Fast Track, this program initiated by our technology partner Intel focuses on any kind of reference architecture to build cloud infrastructures. But Fujitsu as one key contributor focuses on reference architectures for building Private Clouds on-premises, which are all different to our contribution at Microsoft Private Cloud Fast Track. Beside that we build solutions with different Private Cloud management stacks, Fujitsu’s own solution using ServerView Suite, VMware vCloud Director and Microsoft System Center. We also integrate various elements of our cloud-optimized product offering (e.g. Fujitsu PRIMERGY BX, CX and RX – described in further sections of this white paper) in our reference architectures. In cooperation with Intel we are continuously setting up new configurations for different customer needs. We use the Intel Cloud Builder Program to provide our customers with publicly available guidance including a very detailed description of how to build their Private Cloud. Page 11 of 42

  14. 14. Insights Server Virtualization and Private Clouds Economies of scale Fujitsu PRIMERGY BX Lots of companies are placing greater emphasis on the operations of their IT environments not only to gain a competitive advantage in the market but also because IT services and applications have become a critical element in day-to-day business and workforce productivity. The demand of compute and storage capacities is continuously on the increase for server virtualization and cloud computing in particular. Due to this increasing demand, your server rooms have to host a large number of often different hardware platforms. This makes your environment extremely complex and difficult to manage, leading to high costs due to personnel-intensive administration on the one hand and excessively required space on the other hand. For the operation of these systems the energy required for power and cooling emerges as an increasing share of the costs compared to the pure acquisition costs. For many IT organizations in this situation the blade server environment, in combination with virtualization or cloud technologies, is the IT infrastructure of choice to achieve considerable benefits in these areas – the ideal basis for ensuring more flexible use of server resources. Fujitsu PRIMERGY BX Blade Servers provide a faster, simpler and lower-cost way to build and run an IT infrastructure. On top of the benefits achieved from server virtualization or Private Cloud computing, Fujitsu PRIMERGY Blade Servers provide an improved management, greater availability and operational efficiency through a shared infrastructure and virtual input/output. Like all PRIMERGY servers, they ship with Fujitsu’s ServerView software suite, allowing easy, centralized monitoring and management of server, storage and network resources. This may also enable you to redeploy scarce IT resources to value-creating tasks. You have the choice of two Fujitsu PRIMERGY BX Blade Server chassis that reflect Fujitsu’s quality and experience in server design.

  16. 16. Insights Server Virtualization and Private Clouds Cloud eXtension servers Fujitsu PRIMERGY CX Both server virtualization and cloud computing deal with large-scale use scenarios, which will inevitably grow to encompass broader service requirements in order to map individual business dynamics. Therefore, the server infrastructure has a very important impact, especially if much computing power is needed. On the other hand, traditional data center facilities do not easily keep pace with those massive compute capacity demands, since they have to master additional challenges: The Fujitsu PRIMERGY CX Cloud eXtension servers are targeting large scale-out server deployments. ■■ Increased power envelopes and cooling requirements for those servers and related infrastructure ■■ Limitation in data center floor space, and the requirement for more computing power in a limited amount of space ■■ Limited budgets enforcing minimized initial purchase costs and subsequent maintenance costs and operational spending ■■ The need for more efficient manageability and less complexity in the operation of massive scale-out compute resources The Fujitsu PRIMERGY CX Cloud eXtension servers are Fujitsu’s platform for cloud computing, high performance computing (HPC), service provider and any large scale-out computing server farm. They focus on providing large data centers with massive scaling power for x86 servers, while at the same time delivering new data center economics for server density, energy consumption, heat optimization and lower overall operational costs. The Fujitsu PRIMERGY CX server family has everything customers need to achieve a new dimension of cost-effectiveness with a cloud data center. Due to their innovative scale-out design, the Fujitsu PRIMERGY CX servers require less space per rack and less energy heat per server as compared to conventional rack servers. They pay dividends in significantly lowered operating expenses, easier installation and more aggregated computing power in the data center at lower all around investment.

  17. 17. Fujitsu PRIMERGY CX400 S1 Scale-out smart with Fujitsu PRIMERGY CX400 Fujitsu PRIMERGY CX400 multi-node server provides a condensed form factor, enabling you to scale-out smart by packaging 4 independent dual-socket server nodes and up to 24 local storage drives into a consolidated 2U rack enclosure. Fujitsu PRIMERGY CX400 fits smartly into existing data center racks, by providing full compliance to conventional front-to-back airflow, standard 19“ housing of the CX400 chassis and rear connectivity for communication. In this way, team play with an existing rack server infrastructure is easy to achieve. Its ‘4 in 2U’ granularity results in half of the rack space used, lower hardware investment and consolidated efficiency in management for the same performance as compared to standard rack servers. The result is significantly higher performance per standard 19“ rack. Spend small The minimalistic design of Fujitsu PRIMERGY CX reflects the fact that scale-out applications stacks use software functions in the solutions architecture to care for failover and redundancy. This means that hardware-based redundancies can be replaced by those software functions, thus reducing the number of hardware components required with each server unit. And that in turn pays dividends streamlined CX server units, cutting down procurement costs compared with conventional rack server configurations. The space-saving design also ensures that extensions in the data center do not require additional square footage. The result is savings in the cost and work of providing the physical infrastructure. All this has a positive impact on your IT budget and your capital expenses: Depending on the configuration, you can slash these costs by up to 20% with the Fujitsu PRIMERGY CX servers, compared with traditional rack servers. respect to the And that in turn pays dividends with respect to the streamlined CX server units, cutting down procurement costs compared with conventional rack server configurations.

Additionally a choice of PRIMERGY CX dual-socket server nodes with the latest Intel Xeon processor E5 family without (1U height) and with (2U height) GPGPU (General Purpose Graphics Processing Unit) options enable great flexibility to match different solution stacks with Fujitsu’s PRIMERGY CX400. Due to the more flexible configurability, only CX400 can use HPC-optimized GPGPU acceleration units. Page 17 of 42
  18. 18. Insights Server Virtualization and Private Clouds Integrated server lifecycle management ServerView Suite Companies today expect considerably more from their IT departments than just the safeguarding of computer operations: Irrespective of the economic situation the pressure to continue to provide services, which are equal to or even better than the previous ones, is on the increase while budgets are frequently stagnating. To ensure that this task does not become insurmountable Fujitsu has been continuously revising system management functionality in order to meet these increased demands. The focus is traditionally on those functions, which ensure fail-safe and flexible operation of servers in addition to the constant availability of business-critical data and which also facilitate their consolidation. Our key attention was recently placed on integrating technologies for the virtualization, dynamization and automation of IT landscapes up to their integration in cross-location and corporation solution concepts, e.g. cloud computing. ServerView Suite is the management tool from Fujitsu used for the administration of industry-standard servers. Its focus is traditionally on those functions, which ensure fail-safe and flexible operation of servers in addition to the constant availability of business-critical data and which also facilitate their consolidation. Fujitsu’s ServerView Suite offers comprehensive administration covering the overall lifecycle of individual computers as well as entire machine parks and which combines decisive cost benefits with maximum performance and user-friendliness. Although existing IT capacities are better used thanks to virtualization and a medium to long-term reduction can even be achieved with them, administrative spending grows compared to conventional infrastructures with their clear-cut allocation of servers and applications. Therefore, companies need a management platform, which Page 18 of 42 combines a consistent view of the IT landscape with comprehensive functions that are centrally managed from a single point of control. Fujitsu ServerView Suite is one such platform which is also easy to understand and operate. Functionally, it is divided into the five subsections: Deploy, Control, Dynamize, Maintain and Integrate. It is designed for use in so-called Open Systems environments, i.e. on industry-standard servers which run under the operating systems Windows and Linux (SuSE and Red Hat) or are used as hosts for VMs that use a hypervisor like VMware ESXi, Citrix XenServer or Microsoft Hyper-V. Standardized administration of physical and virtual servers As one of the core components in the subsection ‘Control’ Fujitsu’s ServerView Operations Manager (SV OM) supports the standardized administration of all physical and virtual servers in the network. This enables ‘control in just a few steps’ and at the same time ensures increased system availability. A well arranged management console that gives administrators a clear overview of the states of physical servers, VM hosts and virtual machines. It can be used to perform all the important basic operations (starting/stopping, interrupting/resuming and restarting servers). Furthermore, it shows all the configuration parameters in full, thus creating at the same time the basis for detailed performance monitoring and coherent event management. The subsection ‘Dynamize’ combines a series of special system management tools, which above all permit dynamic and efficient use of physical and virtual resources. They differ from the prevalent tools in SV OM by the fact that they also have comprehensive functions for the automated provision and administration of IT infrastructure resources. This includes the following products: ■■ Fujitsu ServerView Virtual-IO Manager (SV VIOM) ■■ Fujitsu ServerView Resource Orchestrator Virtual Edition (ROR VE) ■■ Fujitsu ServerView Resource Orchestrator Cloud Edition (ROR CE) Efficient Virtual-IO Management The aim of Fujitsu ServerView Virtual-IO Manager (SV VIOM) is to ensure as smooth and efficient as possible communication of the PRIMERGY blade and rack server with clients and storage arrays. For this purpose the module allocates previously defined virtual network addresses to the individual servers and also determines via which interfaces they are to establish connection to the LAN or SAN and how they are to be booted. To enable this to work the SV VIOM saves all the specific information about the computers (e.g. MAC addresses and WWNs) in a separate, hardwareindependent server profile, which is kept in a central repository outside the server. http://reshaping-datacenter.ts.fujitsu.com/
  19. 19. As a result, individual applications can be started without any further configuration effort by the administrator allocating a specific profile to a server and by using the address previously defined for this purpose. Ultimately, the SV VIOM creates a separate domain for server management, thus separating it completely from LAN or SAN management. Any conflicts and overlapping between server, LAN and storage management are ruled out from now on, because through using constant virtual addresses there are no changes in LAN and SAN management. Automating server lifecycle operations Fujitsu ServerView Resource Orchestrator Virtual Edition (ROR VE) is a system management tool that delivers integrated administration of physical and virtual servers. By simplifying and automating server lifecycle operations across both physical and virtual environments, IT organizations can increase the efficiency of their day-to-day server operations. Time for deploying or exchanging servers can be reduced by up to 90%. Moreover, ROR VE enables cost-efficient N+1 high availability. IT organizations can now protect more servers without paying a premium for dedicated high-availability tools like cluster software. By assigning one or more spare servers to a pool of production servers, it is possible to automatically failover any production servers to the spare server in the event of hardware or operating system failures. Business applications can be resumed without any administrator intervention. Compared to manual recovery processes, server recovery time is reduced significantly, thus resulting in faster responses to server failures. This applies to both physical and virtual server environments. Build your Private Cloud infrastructure The most effective way to organize IT infrastructure resources in a Private Cloud environment is to build pools of shared resources. Fujitsu ServerView Resource Orchestrator Cloud Edition (ROR CE) introduces such resource pools and delivers dynamic resource management and cloud service management enabling self-service provisioning for simple and speedy IT delivery. Physical and virtual servers – independent of the hypervisor or a mix thereof (e.g. VMware ESXi, Microsoft Hyper-V, RedHat KVM or Oracle VM) are supported – storage and networks, are automatically provisioned in minutes, at a fraction of the cost of traditional provisioning methods. ROR CE guarantees the availability of IT infrastructures by providing a number of high-availability options at various levels. From the protection of single physical and virtual servers, to recovery support for a complete blade chassis or storage system failure, to disaster recovery in the case of complete site failures.

This capability is enabled through a self-service portal, where a catalog of predefined service templates, resources, and service subscription workflows are available. Once resources are provisioned, Fujitsu ServerView Resource Orchestrator Cloud Edition offers users multiple options to control and customize a given configuration. IT organizations can use the integrated usage metering capability to collect data on how resources are used and who is using them. This information can be used as a foundation for companies that want to implement a charge-back model. At the very least it enables them to report business-critical resource use. Page 19 of 42
  20. 20. Insights Server Virtualization and Private Clouds The Flexible Data Safe Fujitsu ETERNUS DX Data has been growing at an annual rate of about 60% for years and is increasing at the same rate. The demand for virtualization, for server consolidation and cloud computing is rapidly increasing. This is why many storage administrators are familiar with the problem of overload caused by the continual rapid growth in data volume. New applications and an increasing amount of non-structured information and data analyses mean that many IT systems have reached their capacity limits. The I/O requirements of today’s applications have also become more demanding. The market will require storage and servers to have higher performance, higher reliability, greater functionality, and increased cost effectiveness. Many already described key functions like Live Migration, High Availability, Dynamic Resource Scheduling or Disaster Recovery mechanisms, just to name some, cannot happen without a central storage system, which is the center piece of any virtual machine farm and Private Cloud infrastructure. Fujitsu has redefined the standards of enterprise storage with the introduction of the latest generation of Fujitsu ETERNUS DX systems in 2011. Whereas traditional vendors offer different and discrete storage architectures in the entry-level, midrange and high-end segment, the Fujitsu ETERNUS DX approach differs with one uniform system design and uniform system management over the complete product line in all system segments. The only model-specific component is the storage control unit; all other components like disk shelves and management software products are the same for all models. This allows upgrading of smaller systems into larger ones by just exchanging the control unit. Administrators who know how to operate one ETERNUS DX model can run any other model in the same fashion. Customers and partners benefit from this architectural principle through less costs of growth and reduced operational effort. ETERNUS DX – a central piece of virtualized and cloud data centers Storage operations, especially in highly virtualized environments, generate a huge workload in data center administration. This is where Fujitsu ETERNUS SF management software helps with its standardized storage management. If you know how to operate one storage device in the family, you are able to run any of them! Innovative advanced functions help to increase operational efficiency. For example, Thin Provisioning means that the administrator can assign virtual capacity to applications so that the real, existing capacity can be pooled. There is no need to invest up front in disk capacity, which is just reserved for future demands in specific cases and is not used productively in the short term. Fujitsu ETERNUS SF management software also offers close integration with server virtualization offerings, such as VMware. It enables storage systems and servers to work together with onsite failovers during disasters, and it enables servers to offload tasks to the storage system, for example provisioning, cloning or the replication of virtual machines. Fujitsu ETERNUS DX Family – S2 Generation Page 20 of 42 http://reshaping-datacenter.ts.fujitsu.com/
  21. 21. Thanks to a wide range of guard and protection functions, the system family is like a bank safe for the reliable and uninterrupted management of enterprise data. Fujitsu’s ETERNUS DX family supports uninterrupted operations at all levels – from the physical systems to the implementation of flexible disaster recovery concepts. For example, Fujitsu ETERNUS DX integrates perfectly with VMware’s Site Recovery Manager (SRM) solution. SRM simplifies and automates the key elements of disaster recovery: setting up disaster recovery plans, testing those plans, executing failover when a data center disaster occurs, and failing back to the primary data center. Simplifies and automates disaster recovery workflows: ■■ Setup, testing, failover ■■ Turns manual recovery runbooks into automated recovery plans ■■ Provides central management of recovery plans from the VMware vSphere Client From a central management station, the vCenter, all actions can be monitored and managed from one point end-to-end. They can calmly prepare the emergency plan, test it and improve it where necessary without any impact on the running operations. All actions are logged and are available for an audit. One key challenge for each storage vendor is to support virtualization and cloud as best as possible. It therefore makes sense to move storage-intensive tasks from the servers executing the applications and perform them directly in the storage system. To enable this, hypervisor and cloud management vendors are delivering APIs to allow greater interaction with storage system. ETERNUS DX provides answers Within our seamless Fujitsu ETERNUS DX family concept we offer enterprise functionality right from the start. Improving storage utilization rates by implementing the Thin Provisioning feature is becoming a critical success factor for any organization. This feature allows you to break the traditional link between allocated and purchased capacity, thus by starting with a low investment you can operate storage systems more efficiently. The support of standard interfaces and APIs (e.g. VAAI, VASA, …) for virtualized IT infrastructures becomes an integral part of Fujitsu ETERNUS DX disk storage systems. Since hypervisors are built to share storage resources between clustered servers, a better mechanism was needed to lock and unlock locked storage. This led to the creation of the VAAI primitive known as Hardware Assisted Locking or Atomic Test and Set, which drastically accelerates I/O operations when resources are shared. This type of hypervisor-driven storage functionality is likely to continue to grow in importance in the future, with storage arrays adapting to the demands of virtual data centers. End users have been very enthusiastic about the impact of this sort of array integration with the hypervisor. It allows them to take better advantage of the advanced features of their storage arrays, and results in dramatic performance improvements. Fujitsu ETERNUS DX is the right answer, it is a highly cost-effective ‘all in one’ solution that meets the full range of today’s storage needs while enabling rapid scaling or reconfiguration to meet the needs of tomorrow. Just one example: in an effort to simplify the interaction and to make it more efficient, VMware developed the vStorage APIs for Array Integration – in short VAAI. This API separates the tasks of the hypervisor and its storage devices, enabling each to focus on what it does best; virtualization-related tasks for the hypervisor and storage-related tasks for the storage arrays. With VAAI, storage array vendors can directly integrate their storage hardware and applications with vSphere. VAAI enables certain storage tasks, such as cloning, to be offloaded to the storage array, which can complete them more efficiently than the host can. Rather than use host resources to perform the work – that was required prior to VAAI – the host can simply pass on the task to the storage device Page 21 of 42
  22. 22. Insights Server Virtualization and Private Clouds What about data protection? We have already mentioned the need to have central, accessible storage as an elementary component of server virtualization and Private Clouds. Therefore, storage consolidation has to be done first to leverage all the capabilities of server virtualization and Private Cloud computing. Even in highly available server configurations it is inevitable that the applications have access to ‘their’ data at any time. Your data are one of the most valuable assets of your company and storage consolidation on its own may be not enough to protect this essential asset. This is why you also have to take care of data protection. So let’s spend some time on data protection with true tape virtualization and backup to disk with de-duplication. Complex environments The data protection infrastructures that have evolved in data centers have led to complex IT environments that are difficult to operate and maintain, thus making them error prone. This accounts for the heterogeneous data protection landscapes having various server architectures, virtualization layers, diverse backup software solutions, and tape libraries based on very divergent technologies. Most data backup scenarios today resemble a collection of individual islands that have little or no synergies between them. It comes as no surprise that backup process management and infrastructure maintenance are extremely complex and expensive. Administrators just try to keep things running and avoid making any changes for as long as possible. They know that as soon as one change is made, a series of other changes are generally needed at other points in the infrastructure. For example, if the use of a new generation of tape drives is planned, administrators have to be sure that these will function correctly with the existing HW infrastructure and software, and they need to know if a migration of the tapes will be required. What’s more, data backups on hard disks and on tape are generally performed separately. This is not only inefficient from an operational point of view, it also hinders the definition of flexible SLAs (service level agreements) for data protection. Ideally, users should always have the option of deciding when to use disks, tape, or even a mix of both in order to keep the speed of backup and restore in balance with the costs of media. Page 22 of 42 One-for-all Fujitsu ETERNUS CS High End radically simplifies data protection in heterogeneous IT environments supporting the consolidation of backup systems on a large scale, and it offers an easy way to provide disaster resilience for backup and archiving. It sets a virtualization layer between servers and tape libraries. From the server viewpoint it is one huge virtual tape library. The servers write data on the hard disks of the ETERNUS CS High End. From there Fujitsu ETERNUS CS High End automatically manages all the data. It can be decided at any moment in time whether the data remain on disks, are written to one or several tape libraries, or are available on disks and tape. The data protection appliance takes care of the complete process between servers and disk/tape systems. The result is a real and automatic ILM (Information Lifecycle Management). This supports highly flexible SLAs because users can decide at any time which data should be kept on disks, which on one or several tape systems, or on tape and disk. Therefore, the different requirements of business units for backup/restore and archiving/retrieval services in terms of costs, capacity, and performance can be satisfied with just one solution. True Tape Virtualization stands for the unique connectivity offered by Fujitsu’s ETERNUS CS High End, which enables enterprises to simplify the structure and the operation of heterogeneous environments, like mainframe, IBM system i and open systems. Fujitsu’s ETERNUS CS High End features universal tape interfaces, making it compatible with all market-leading libraries. It supports all commercially available backup applications so that it can be integrated into existing IT environments. This supports the comprehensive consolidation of backup systems and offers maximum investment protection. In addition to that, ETERNUS CS High End facilitates the HSM (Hierarchical Storage Management) functionality to support archive functions like long-term archiving, and also archiving for compliant purposes (KPMG-certified) within the same appliance.

  23. 23. Proven data protection appliance Fujitsu ETERNUS CS High End has been the first choice to drive efficient data protection for more than 12 years. This Fujitsu appliance is used around the world by the largest data centers in data-intensive segments such as financial services, telecommunications, public administration agencies, industry, and IT service provisioning. This is largely due to the unique performance delivered by Fujitsu’s ETERNUS CS High End, plus the fact that it is a platform designed on the basis of real-world best practices. From the very beginning, this data protection appliance was developed in close cooperation with users, and its ongoing development has continued for many years in collaboration with a well-established user group. That translates into optimal support from customers and keen awareness of the demands arising from daily system use. Backup to disk with deduplication Especially in virtual and Private Cloud environments, where data are concentrated on few physical servers, the crash of one of these servers causes the loss of multiple data and therefore backup is a must. On the other hand virtual and Private Cloud environments pose unique data protection problems, because backup volumes are quite large – due to redundant data distributed over many instances. This is where Fujitsu ETERNUS CS800 can unfold its complete strength. ETERNUS CS800 by Fujitsu is the genuine storage guardian, making certain storage is kept safe and free of duplicates. It combines advanced de-duplication technology with ultra-secure and fast backup to disk – and radically simplifies both. Deduplication makes sure that identical data are stored only once, thus reducing disk capacity requirements by up to 95%. The solution’s replication capability provides automated and encrypted transmission of the data between different sites to make the backup disaster-proof. And in case a disaster occurs, the disk-based solution provides fast and easy restoration of all data to rebuild the virtual or Private Cloud environment.

  24. 24. Insights Server Virtualization and Private Clouds Fujitsu integrated cloud infrastructure solutions Cloud-based IT resourcing – private, public or hybrid – is an agenda-topping issue for CIOs and CEOs everywhere, who increasingly regard cloud infrastructures as a strategic initiative and opportunity both to drive business agility and to reduce costs. Accordingly, IT organizations that plan to act as cloud service providers, either for their internal business units or for external customers, are under growing pressure to align data center operations with these expectations. The challenge is finding ways to implement cloud infrastructures fast and at minimum risk. flexible but reliable IT infrastructures that: Fujitsu offers two integrated cloud infrastructure solutions addressing different customer requirements: Major questions for data center managers are: ■■ How do we set up and integrate all the components to run a highly reliable, highly secure cloud infrastructure? ■■ How do we keep the complete infrastructure in a consistent state while reducing maintenance effort and costs? ■■ How can we keep cloud services easy and convenient to manage, and ensure cloud computing delivers on its promises to users?

  25. 25. The “Do-It-Yourself” Approach Today, IT organizations typically follow a do-it-yourself approach when it comes to introducing on-premise cloud infrastructure. At first glance this seems appealing – given the highly individual profile of demands, a highly customized approach using the enterprise’s own IT resources appears the best road to take. Yet there is an inevitable trade-off between the benefit obtainable with a customized solution, and the sheer effort and expense of making it work – with all the accompanying risks that jeopardize project timelines and goals. IT managers have to be very clear on how much effort and time they are willing to spend on design, implementation and test of complex infrastructure projects. They will be engaging with questions such as: Solution design ■■ Do we have the time and expertise (solution architects) to evaluate the market and select the right mix of components from the myriad of hardware and software products from so many different vendors? Can we keep up-to-date with developments in every relevant area, to be certain we always incorporate the latest innovations and developments? Implementation ■■ Do we want to deploy significant staff resources on coordinating shipment dates for each single product in our highly customized approach? Do we have enough technical experts with the product skills to assemble, integrate, configure and maintain the end-toend cloud infrastructure? Test ■■ Can we afford additional time and resources for quality assurance of the entire solution stack, covering all component dependencies across servers, storage, networks, operating systems, virtualization and cloud management software? If the answers to these questions fall short of satisfactory, a different approach might be a better way to accomplish objectives. The pre-integrated infrastructure approach In this alternative approach, Fujitsu takes full responsibility for all the project phases – solution design, implementation and test. Working on the basis of proven best practices, Fujitsu solution architects from all relevant product divisions create an architectural design. Fujitsu integration labs integrate solution components and create proof-of- concept implementation that fit in with real-life environments. This also includes a full testing and approval process for the solution, making sure all components work together smoothly. Customers get a fully designed, pre-integrated and pre-tested dynamic infrastructure solution combining all hardware and software components. This delivers fast, easy ramp-up of the on-premise cloud infrastructure, reducing the implementation risk for organizations and accelerating the time to production. Solution Life Cycle Management Like the process of implementing an on-premise cloud infrastructure, managing change in an up-and-running infrastructure is a challenge. Yet unlike implementation, life cycle management is not a one-off investment of time and effort – this is an ongoing task. It takes complex processes in the IT organization (and ties up significant staff resources) to manage the stream of ongoing updates and orchestrate support from multiple vendors. The first challenge for internal IT administration is merely to find out when and which updates are available for the various hardware and software components in the complex technology stack. What makes it particularly difficult is having to juggle the many single patches from multiple vendors – all of which arrive at different dates because they have separate release cycles. IT administration then has to apply patches using a variety of patch tools. And finally, they need to run a quality assurance test to verify that the infrastructure is still in a consistent state. To reduce effort and associated costs, Fujitsu integrated cloud infrastructure solutions provides a “Solution LifeCycle Manager”, a single central tool that controls all life cycle management tasks using quality-assured update packages including a consolidated set of all relevant updates, patches and security fixes. IT organizations benefit from increased infrastructure consistency and fewer planned downtime windows, all contributing to the goal of maximizing the time the IT infrastructure runs in operation and not in maintenance mode. Typical life cycle management tasks are: ■■ Perform proven, consistent and verifiable initial setup ■■ Track and manage the configuration over the complete solution life cycle ■■ Software update management including management of software patches, firmware updates and new software releases ■■ Hardware upgrade management including automatic setup and configuration of hardware extensions ■■ Assistance in replacing failed hardware components Page 25 of 42
  26. 26. Insights Server Virtualization and Private Clouds SAP-aware IT infrastructure FlexFrame for SAP When companies want to optimize their IT operations, they often look to server virtualization as a natural first step. Many such virtualization projects include goals like consolidating the IT infrastructure, reducing costs, improving operational efficiency, introducing or enhancing server virtualization, increasing the quality of service, disaster recovery and introducing cloud computing concepts. To achieve these goals, companies need to take an intelligent, comprehensive virtualization approach. But what about the applications? As the headline indicates, let’s take SAP. Various user Page 26 of 42 departments, teams and external service providers are involved throughout the entire lifecycle – from initial planning to operation and adaptation of SAP systems. Discontinuities at the seams between the individual phases as well as within them – for example in the operation phase between server, storage, network, database and application administration – typically cause time-consuming, cost-intensive aggravation. Organizational and technological factors are the reason. http://reshaping-datacenter.ts.fujitsu.com/
  27. 27. FlexFrame for SAP To overcome the aforementioned problems and as a SAP Global Technology, Hosting and Services partner, Fujitsu has been cooperating successfully with SAP for almost four decades in various innovative areas, giving us insight into the SAP customer base and its requirements. Based on that experience, Fujitsu developed FlexFrame for SAP, an end-to-end dynamic infrastructure solution that helps companies to optimize their IT environment and lets them manage servers, virtual machines, storage and networks from the SAP application requirements point of view. FlexFrame for SAP – move towards SaaS FlexFrame for SAP is also an ideal foundation for cloud computing environments, meeting all the key requirements such as flexibility, efficiency and reliability.

  28. 28. Insights Server Virtualization and Private Clouds What about client virtualization? PC workplaces represent an important productivity tool supporting users in doing their business, but they also raise a number of serious challenges, especially for the IT organization. Lifecycle management has proved to be increasingly complex and difficult. The various types of end users have to be treated differently. As recovery after failure can be time-consuming, the productivity of the end user concerned is considerably limited. The ubiquitous risk of data theft and data loss makes it difficult to meet compliance demands. And whenever you have to react on new demands and changes in the market, you will experience that flexibility and speed are rather limited. However, the costs are high and often not fully transparent. This simplifies management even more, as software can now easily be deployed and updated without touching numerous devices. Upgrades are achieved without disrupting the end user. Recovery from failure happens by the click of a mouse, which increases availability significantly; even disaster recovery concepts can be applied. The reason for the high complexity and the consequences resulting from it is the tight coupling of hardware, operating system, applications and user personality, which makes these components and their lifecycles dependent on each other. Any change in one of these components will impact its adjacent components, too. And finally, you can flexibly access your workplace environment anywhere and from any device. Breaking the tight coupling correspondingly will make the components and their lifecycles independent. This is exactly what virtualization stands for. From tight coupling to virtualization User Apps OS HW User Apps OS HW Managing single instances of components instead of many unique monolithic desktops reduces complexity, simplifies management, increases flexibility and speed, improves service quality and finally reduces costs. Virtualization can happen on each component layer. Depending on where virtualization happens, we speak of user virtualization, application virtualization, operating system image virtualization or device virtualization. In combination they enable a dynamic and fast assembly of IT workplaces on demand, be it for new users or with recovery after failure. Virtualization enables centralization Due to the separation of the workplace components from each other, virtualization enables you to move applications, user personality, data or even entire workplaces from the user’s device into the data center. Page 28 of 42 The fact that all data are hosted centrally eliminates the risk of data theft. Data backup no longer depends on the end user, thus minimizing the risk of data loss and improving security. This not only helps you fully meet compliance demands, it even makes your compliance audit-proof. Various concepts for different requirements When moving things into the data center, there is no one way. There are various concepts for different requirements. Hence, there is no universal answer to the question ‘what to use when’, but indications as to what might be applicable in many cases. The Hosted Shared Desktop with applications being shared among several users is absolutely sufficient for task workers using only a few standard applications and also provides maximum efficiency. In order to optimally use server resources in the data center, it is advisable to run the delivery server instances as virtual servers. The Hosted Virtual Desktop with full personalized desktops running as virtual machines on servers in the data center is recommended for knowledge workers with higher demands regarding personalized environments. From a technical perspective, this concept is identical to server virtualization, apart from the fact that the virtual machine is a virtual desktop instead of a virtual server. Offline use is an essential requirement for mobile users who are frequently on the move. With the Local Virtual Desktop, virtual desktops run on a mobile device. As soon as you are connected to the corporate network, local data changes are automatically synchronized with the data center, as system updates and patches will affect the local virtual desktop. If centralization is demanded for power users with high performance requirements, the Hosted Central Desktop with dedicated workstation hardware in the data center and which flexibly accessible from any device is an option. In certain use cases, e.g. in the education segment, it can be interesting to stream entire desktop images to stateless PCs, on which all applications are executed locally. This concept is also known as the Local Streamed Desktop. http://reshaping-datacenter.ts.fujitsu.com/
  29. 29. Application and user virtualization, as well as OS image virtualization are always beneficial, no matter which of the other models is applied. However, as one size does not fit all, the optimum solution will usually be an intelligent combination of various models. Fujitsu’s Virtual Client Computing approach Going for virtual client computing, you will face an ever-increasing number of technologies from multiple vendors. Understanding which technologies bring the most beneficial results is an increasingly complex and time-consuming task. Selecting the appropriate technologies according to business requirements, evaluating, testing and combining them, is a challenge, which should not be underestimated. Once you have decided on the optimal recipe, the next steps will be the design and implementation of the future infrastructure, going along with the integration of numerous building blocks, such as virtualization software, servers, storage systems, access devices and more. Uncertain project duration and a multitude of risks can be the consequence. Fujitsu’s virtual client computing approach is concerned with eliminating complexity, reducing your work effort, and reducing the overall risk in putting all the pieces together and helping you overcome the many hurdles in realizing a successful solution. After having identified the potential cost savings and performance improvements, the future workplace strategy will be jointly defined with you, according to your business needs and goals. Correspondingly, the required technologies are selected. Based on the results of a proof-of-concept, which is accurately prepared and executed together with you, the future workplace infrastructure will be designed and implemented. All this happens in structured and standardized processes, based on extensive experience from real customer projects. Fujitsu not only provides all products needed for virtual client computing, such as virtualization software, servers, storage systems and access devices; Fujitsu also offers any kind of additional services including versatile financial options (financial services), the management of your individual solution (managed services), and cloud services. You will find more information on these topics in further sections of this white paper. Additionally, there are even infrastructure bundles for certain scenarios available, which enable a virtual client computing solution to be out of the box. Optimized hardware configurations are pre-installed with the required software, and therefore ready to run. Fujitsu is an one-stop shop that provides everything related to virtual client computing from a single source. This helps reduce complexity, project time and risk, while improving flexibility, efficiency and service quality.
