Virtual Clustered Multiprocessing (vCMP) allows administrators to segment physical ADC resources into independent virtual ADCs. It provides true isolation between instances through a purpose-built hypervisor designed specifically for F5 hardware and software. This deep integration enables high performance virtual instances without sacrificing reliability. It allows organizations to independently operate and manage virtual instances while maintaining interoperability with existing equipment.
Enterprise data centres have traditionally used servers and storage that typically scale only to a few nodes. Even small capacity or performance scales required large installation increments or worse, required replicating the existing IT infrastructure, which is prohibitive in terms of cost and space. An important impediment was that as storage capacity increased, system performance and efficiency suffered. In addition, IT budgets came under pressure and created high entry barriers to scale for enterprise class data centres. However, virtualization and cloud platforms are changing that. IT departments can now linearly scale to several server and storage nodes rapidly, for capacity and performance without compromising on efficiency and to keep costs under control. This helps save space via hardware consolidation, improves productivity, and derives a competitive advantage through increased availability, lean administration, and fast deployment times.
This Desktone hosted webinar features IDC's Enterprise Virtualization Software Sr. Analyst Ian Song will discussing how businesses can elevate their desktops to the cloud easily and affordably. Desktops are ripe for change. Windows 7 migrations, mobile devices and cost overruns are driving businesses to seek an affordable and flexible alternative. Until now, cost and complexity have been barriers to implementing traditional Virtual Desktop Infrastructure (VDI) solutions.
IDC and Desktone discuss the dynamics of the cloud, eliminating barriers to VDI, & benefits of moving desktops to the cloud. By moving desktops to a cloud-hosted service model, instead of an internally deployed and managed data center, companies can realize all the promised benefits of desktop virtualization—centralized management, improved data security and simplified deployment— without the exorbitant cost, limitations or hassles of VDI.
The document discusses a survey of IT professionals that highlights the untapped benefits of virtual desktop infrastructure (VDI) and desktop as a service (DaaS) for mobile workforces. While most respondents were familiar with VDI and DaaS, few have adopted these solutions. The document examines the advantages and challenges of VDI, which provides centralized management but requires upfront infrastructure costs, and DaaS which outsources infrastructure maintenance and reduces costs through a subscription model. It suggests that a combination of VDI and DaaS along with multiple endpoint devices can optimize resources and productivity for organizations.

This document provides an overview of virtualization technology. It discusses how virtualization works through the use of a hypervisor and management software to allocate resources across virtual machines. The benefits of virtualization include server consolidation and increased efficiency. Issues that need to be addressed include performance considerations when consolidating workloads, security risks introduced by added software layers, and ensuring compliance across virtual machines. The document provides guidance on getting started with virtualization, including understanding workloads, building a business case, training staff, and examining policies.
The process of virtualization enables the creation of virtual forms of servers, applications, networks and storage. The four main types of virtualization are network virtualization, storage virtualization, application virtualization and desktop virtualization.
This is a paper was written by David Reine, an IT analyst for The Clipper Group, and highlights IBM’s SAN Volume Controller new features, capabilities and benefits. These new capabilities were announced on October 20, 2009Virtualization is at the center of all 21st Century IT systems, yet many CIOs fail to fully understand all of the benefits it can deliver to the data center operation. When we think of virtualization, we think compute, network, and storage—and we mostly think about driving up utilization on each. Storage controllers have always offered the ability to carve out pieces of real storage from a large pool and deliver them efficiently to a number of hosts, but it is storage virtualization itself that offers improvements that drive operational efficiency. IBM has been quietly addressing storage virtualization with SAN Volume Controller (SVC) for the last six years, building up a significant technical lead in this space.
Strange but true: most infrastructure architectures are deliberately designed from the outset to need little or no change over their lifetimes. There are two main reasons for this:
1. Change often means outages and customer impact and must be avoided
2. Budgets are set at the beginning of a project and getting more cash later is tough
Typically, then, applications are configured with all of the storage capacity they need to support the wildest dreams of their business sponsors (and then some extra is added for contingency by IT). Equally, storage is always configured with the performance level (storage tier) set to cope with the wildest transactional dreams of the business sponsor (and guess what? IT generally adds a bit more for good measure.).
No wonder storage is now one of the largest cost components involved in delivering and running a business application.

Virtualization is a technique that allows sharing of physical resources among multiple customers and organizations. It does this by assigning logical names to physical storage and providing pointers to the physical resources on demand. Virtualization plays a fundamental role in cloud computing by efficiently delivering Infrastructure-as-a-Service solutions. It allows sharing of a single physical instance of a resource like a server, storage, or application among multiple users. This helps reduce costs for cloud providers through server consolidation and more efficient use of hardware resources. Some benefits of virtualization in cloud computing include better hardware utilization, increased availability of resources, easier disaster recovery, and energy savings.

Cloud Technology and Virtualization
There are many reasons companies and organizations are investing in server virtualization. Some of the reasons are financially motivated, while others address technical concerns. Server virtualization conserves space through consolidation. It's common practice to dedicate each server to a single application. If several applications only use a small amount of processing power, the network administrator can consolidate several machines into one server running multiple virtual environments. For companies that have hundreds or thousands of servers, the need for physical space can decrease significantly. Server virtualization provides a way for companies to practice redundancy without purchasing additional hardware. Redundancy refers to running the same application on multiple servers. It's a safety measure -- if a server fails for any reason, another server running the same application can take its place. This minimizes any interruption in service. It wouldn't make sense to build two virtual servers performing the same application on the same physical server. If the physical server were to crash, both virtual servers would also fail. In most cases, network administrators will create redundant virtual servers on different physical machines. Virtual servers offer programmers isolated, independent systems in which they can test new applications or operating systems. Rather than buying a dedicated physical machine, the network administrator can create a virtual server on an existing machine. Because each virtual server is independent in relation to all the other servers, programmers can run software without worrying about affecting other applications (Strickland 2013).
Cloud computing is ideal for small companies, as it’s cost-effective, saves time and energy, and it allows for a high level of customization. According to Forbes, a 2009 study found that cloud computing could save up to 67% of the lifecycle cost for server deployment on a large scale. Another study found that using cloud solutions generally results in higher investment returns (when compared to an on-site system). There are further cost saving benefits, such as less need for expensive hardware and software, and no need for physical networks or IT maintenance. Also, cloud systems are usually ‘pay-as-you-go’, so you only pay for what you use. There are no upfront investments, and IT requirements can be easily budgeted for. Also, various cloud services can either be added or scaled back, depending on where your business is, and how much growth is taking place. The cloud is also highly customizable: you can select what platform you want, which payroll software to use, and what email marketing tools you require – all from different vendors, and all individually configurable (K2 SEO 2013).

This document discusses different types of virtualization technologies. It begins by defining virtualization and describing its benefits such as standardization, rationalization, and improved efficiency. It then categorizes various virtualization types including server/platform, desktop, software, system resources, data, and network virtualization. For each type, it provides details on sub-types and discusses opportunities and challenges. The document aims to help consultants, administrators and decision makers understand and evaluate different virtualization options for their organizations.
This document discusses cloud computing and related concepts:

This document provides an introduction to cloud computing, discussing its key attributes of scalable, shared computing resources delivered over a network with pay-per-use pricing. It describes the different delivery models of cloud computing including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). The document also discusses virtualization techniques that enable cloud computing and how cloud computing enables highly available and resilient systems through capabilities like workload migration and rapid disaster recovery.
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. It allows users to access technology-based services from the network cloud without knowledge of, expertise with, or control over the underlying technology infrastructure that supports them. Key benefits of cloud computing include lower costs, better scalability and flexibility.
Small and medium-sized businesses can reduce software licensing and other OPE...Principled Technologies
A cluster of these servers ran a mix of applications with up to 27 percent better application performance than a previous-generation cluster, which

Conclusion
As you do your best to balance timing, budget, IT resources, and your current and anticipated server needs, consider how opting for newer servers could help your business. As our testing showed, there are clear benefits to choosing servers that support such workload requirements as keeping databases running at a quick pace and delivering speedy hosting for your business’s website. Plus, a solution that offers the capacity and software features to perform well while natively supporting Kubernetes containers could add value in terms of setup, flexibility, scalability, and cost-effectiveness. And you can achieve all of this and possibly reduce OPEX in the process.
In our testing with a mixed workload that reflects some of the needs common to small and medium businesses, a cluster of 16G Dell PowerEdge R7615 single-socket servers powered by 4th Gen AMD EPYC processors outperformed a cluster of previous-generation 15G Dell PowerEdge R7515 servers, with improvements of up to 27 percent and latency reduction of up to 50 percent. These results show that upgrading to the new Dell solution can be a smart step toward meeting the needs of your users now and in the years to come.
The document discusses server virtualization and consolidation in enterprise data centers. It notes that many servers are underutilized but some become overloaded during peaks, and server consolidation aims to increase utilization while maintaining performance. Two main virtualization technologies are hypervisor-based (e.g. VMware, Xen) and operating system-level (e.g. OpenVZ, Linux VServer). The document evaluates the performance and scalability of a multi-tier application running on these virtualization platforms under different consolidation scenarios. It also examines the impact on underlying system metrics to understand virtualization overhead.
The document presents IBM's framework of four priorities for organizations to enhance their virtualized infrastructure and maximize business value:
1) Consolidate resources by virtualizing servers to increase utilization and reduce costs.
2) Manage workloads with centralized tools to track status, perform tasks, and ensure service level agreements are met.
3) Automate processes like provisioning and disaster recovery to improve efficiency, speed, and consistency of responses.
4) Optimize service delivery by enabling business users to directly create new services over the web using virtual infrastructure like cloud computing.
The document discusses the emergence of hyperconverged infrastructure (HCI) technology. It describes some of the key issues that led organizations to adopt HCI, including the need for business-IT alignment, operational efficiency, cloud-like flexibility on-premises, and reducing data center complexity. It then provides context around earlier converged infrastructure solutions and how HCI aimed to improve on those approaches.

2. Introduction
Data center consolidation and virtualization have changed the way organizations
look at CapEx and OpEx. Gone are the days when adding new capacity or
applications was simply accomplished by buying "more." Today, CIOs and
architects are looking to maximize the return on investment in hardware and
software through virtualization technologies that enable them to squeeze every
ounce of computing power from their existing data centers.
This is most apparent in the world of application servers, but the potential benefits
for other devices, firewalls, routers, and Application Delivery Controllers (ADCs)
cannot be ignored. Consequently, most vendors offer strategies around multi-
tenancy or virtual appliances in one form or another to provide the same kind of
flexibility for their solutions that OS virtualization offers in the server world.
While both multi-tenancy and virtual appliances improve organizations' deployment
flexibility and their ability to get maximum ROI from both CapEx and short-term
OpEx, these strategies have failed to provide the same kind of high-reliability, high-
performance solutions as traditional purpose-built systems.
Until now. F5 Virtual Clustered Multiprocessing (vCMP) technology, coupled with
Clustered Multiprocessing (CMP) technology, application delivery software,
purpose-built hardware, and virtual edition (VE) solutions, finally gives organizations
a complete, end-to-end virtualization strategy for application delivery.
Consolidation Considerations
As organizations began consolidating their data centers, they quickly realized that to
succeed, they had to eliminate all excess; simply moving remote systems into a
single data center quickly consumed all the space, power, and cooling available.
Additionally, many of those systems used less capacity than was provided by the
hardware they were deployed on. Many organizations also routinely over-
provisioned their server hardware to accommodate future growth or unpredictable
demand. At an individual application level this makes complete sense; however, this
strategy replicated hundreds of times across hundreds of applications resulted in
massive quantities of unused resources simply wasting away in the data center.
Data center appliances also tended to be over-provisioned for the same reasons.
Reclaiming these stagnant resources to minimize the amount of rack space, power,
and cooling needed emerged as a critical goal of data center consolidation.
However, it is still important to account for future growth and unpredictable load. On
paper, commercial virtualization solutions seem to fit the bill, but each has
weaknesses. These solutions come in two general forms: multi-tenancy and virtual
appliances.

weaknesses. These solutions come in two general forms: multi-tenancy and virtual
appliances.
How Conventional Solutions Fall Short
Multi-Tenancy
Many appliance vendors use multi-tenancy to segment their solutions and provide
unique management and operation for disparate groups. Through administrative
partitioning, an organization can configure a device to service multiple customers or
business units without those customers realizing that others are also using the
same physical solution. While this provides the appearance of separation between
tenants, the reality is that all of them share the same hardware resources. Therefore,
if any one customer misconfigures their portion of the system, or causes excessive
use of those resources, it can negatively affect other users. Multi-tenant solutions
provide advanced controls to reduce this possibility (such as processor, memory,
and bandwidth limits); however, the fact that it still remains possible makes these
solutions unfavorable in many cases.
Multi-tenancy has other limitations: a single hardware failure affects multiple
customers; customers must use the same versions of software, which limits
flexibility; and while individual customers only see their unique portion of the system
configuration, the overall configuration of the appliance includes all the
configurations, making it complex and difficult to manage. The result is that while
multi-tenancy achieves many of the goals of consolidation and can reduce CapEx, it
tends to increase OpEx over the long term.
Virtual Appliances
Virtual appliances are also used to address the requirements of data center
consolidation. A virtual appliance takes the software that once ran on dedicated,
purpose-built hardware and ports it into a virtual machine that typically runs on a
general-purpose hypervisor in the same manner that application server virtual
machines do. They can run on commodity hardware and be moved in the event of
failure or resource exhaustion. This provides some significant benefits not
addressed by multi-tenancy. First, each virtual instance is completely independent
from any other virtual instance on the same host—whether it's another virtual
appliance or an application instance. While the virtual appliance still shares the same
hardware with other virtual appliances, the separation is much more distinct and
controlled than in multi-tenancy. Second, if the underlying hardware fails or another
instance causes excessive resource utilization, the virtual appliance can be moved to
another hardware host fairly simply and with little interruption. This helps address
the issue of hardware failures affecting multiple customers and resource limitations
that multi-tenancy generally cannot.

another hardware host fairly simply and with little interruption. This helps address
the issue of hardware failures affecting multiple customers and resource limitations
that multi-tenancy generally cannot.
Unfortunately, when it comes to virtual appliances that do significant amounts of
heavy processing, many organizations are finding that they can't provide the same
level of service as their physical counterparts, especially in consolidated
environments where increased traffic accompanies the consolidation effort. The
dedicated hardware that many of these appliances were originally deployed on was
highly specialized and designed to boost performance beyond what general-
purpose systems are capable of. For example, when appliances had to process real-
time network traffic, the software was tuned for specific network interface hardware;
but in a virtualized deployment, it can only be tuned to the virtualized interface, as
the physical interface is never certain. In addition, processing real-time data
encrypted by SSL/TLS requires dedicated, special-purpose hardware to keep from
adding latency to the network, particularly as SSL keys change from 1024-bit to
2048-bit (requiring five to seven times the processing power). While it is certainly
possible to deploy SSL processing hardware on commodity servers, it must be
deployed on every machine that the virtual appliance might move to, which reduces
the CapEx savings of the consolidation effort.
Even without these concerns, running virtual appliances on the same hardware/
hypervisor as virtualized application instances can be dangerous as their need for
processor, network interface, and memory often starve other applications. This
results in virtual appliances often being deployed as the only virtual machine on an
individual, physical piece of hardware much like traditional non-virtualized versions,
but with the overhead of a hypervisor as well.
While both multi-tenancy and virtual appliances provide additional value over
traditional, single-use appliances, both have drawbacks that limit their overall
benefit. Multi-tenancy lacks complete isolation, fault tolerance, and ease of
migration; and virtual appliances lack the performance of dedicated, purpose-built

Virtual Clustered Multiprocessing
Clustered Multiprocessing (CMP) technology introduced by F5 in 2008 enabled the
consolidation of physical, purpose-built resources into a single virtual entity that
provides the most scalable Application Delivery Controller (ADC) to date. It's the only
solution that provides near 1:1 scaling of performance by simply adding or
upgrading resource blades.
Virtual Clustered Multiprocessing (vCMP) is the industry's first purpose-built
hypervisor—it allows the complete segmentation of those purpose-built, scalable
resources into independent, virtual ADCs.
True, Purpose-Built Hypervisor
All hardware isn't equal—organizations need purpose-built hardware for highly
reliable, high-performance solutions. The same can be said for hypervisors. Most
general-purpose hypervisors are designed to handle the broadest set of possible
physical hardware configurations and guest operating system requirements. This
flexibility is what makes them powerful enough to manage the complexities of
today's modern data center that runs the gamut of hardware and software
combinations.
ADCs, however, are not general-purpose computing platforms. While virtualized
ADCs running on general-purpose hypervisors and commodity hardware have
immense value for application-specific profiles and intelligence, they cannot provide
the scale, high availability, and performance required for core ADC traffic
management. These require purpose-built solutions.
The vCMP hypervisor is specifically designed for F5 hardware, which was designed
to meet application delivery requirements. vCMP was also built to host F5's
application delivery software, not to host general-purpose software. It is an
application delivery hypervisor uniquely tuned and purpose-built for that purpose
and none other. Unlike other vendors' solutions, which deploy general-purpose
hypervisors and attempt to tune them for best-effort performance as an ADC
hypervisor, vCMP is designed from the ground up to be an ADC hypervisor.
Deep Integration
The deep integration between hardware, hypervisor, and ADC software provides
immense benefits over other solutions, most notably in efficiency and reliability.
Because F5 has complete control over the underlying hardware and the overlaying
software, the vCMP hypervisor is more efficient in design and operation than

The deep integration between hardware, hypervisor, and ADC software provides
immense benefits over other solutions, most notably in efficiency and reliability.
Because F5 has complete control over the underlying hardware and the overlaying
software, the vCMP hypervisor is more efficient in design and operation than
general-purpose hypervisors. vCMP needs to implement support only for F5-specific
hardware, and it needs to support only the processes required by F5 software. The
result is a much more streamlined and efficient hypervisor design.
This more efficient hypervisor also improves reliability. Its streamlined nature makes
the vCMP hypervisor easier to maintain and easier to troubleshoot. In addition,
because F5 controls the entire stack, changes in supported hardware or software
that require modification of the hypervisor are also controlled entirely by F5, rather
than third-party developers or hardware manufacturers.
The result of this deep integration is a more stable and controlled platform that
simply performs.
The Payoff
The payoff of a purpose-built hypervisor that's deeply integrated with the underlying
hardware and guest software is the most powerful virtualized ADC solution available
today. With vCMP, organizations can independently operate virtual instances
without sacrificing interoperability with existing equipment, purpose-built hardware,
or orchestration solutions.
With vCMP, administrators can run multiple instances of TMOS, each isolated from
the others. Unlike some implementations, because vCMP is a true hypervisor, the
guest ADCs are completely isolated—so they can run entirely different versions of
ADC software. This means that test and development staff can create new virtual
ADC instances to test new versions of software without any effect on existing
deployments. Or, competing business units can choose if/when they upgrade their
virtual instances to meet their unique business requirements. All they have to do is
provision a new instance, apply their existing configuration, and then test the
upgrade process and results. Any problems can be addressed by simply removing
the instance and starting over. Alternatively, administrators can upgrade individual
instances in place without having to upgrade all instances.
Because each guest is its own complete ADC, individual business units or other
customers have complete control over their deployment, the ability to further
segment their deployment using administrative controls, and the ability to manage
independent logs and configurations. However, a failure or misstep cannot affect
any other virtual instance. Rebooting the instance, runaway processes, and flat-out
misconfigurations are isolated from all other instances.

independent logs and configurations. However, a failure or misstep cannot affect
any other virtual instance. Rebooting the instance, runaway processes, and flat-out
misconfigurations are isolated from all other instances.
When vCMP is deployed on a multi-blade VIPRION system, administrators
can configure the vCMP instances of ADCs in multiple ways. The instances
may exist on single blades, or they may span multiple blades. In addition,
since VIPRION chassis allow new blades to be added on the fly, vCMP
instances can be configured to automatically expand across the new blade
resources without interruption. The primary benefits of vCMP are:
Instances can run different versions
Network isolation
Resource isolation
Fault isolation
All exist within a single VIPRION chassis (with the benefits that provides),
and each instance is completely independent from the others. On-demand
scale with complete control over resource allocation is the best of both
worlds.
The deep integration of vCMP also enables it to work seamlessly with existing
functionality. For instance, CMP allows new compute resources to be added
incrementally and become instantly available to the ADC. When vCMP is in
operation, those new resources can be automatically allocated to existing virtual
instances without any interruption, reboot, or reconfiguration. On the other side of
the stack, when configuring vCMP guest allocation, the hypervisor can directly
assign IP addresses for management and VLAN tags along with the resource
allocation restrictions. Creating a new ADC instance can be done in a matter of

minutes, and a new administrator can log in and start their configuration. Other
vendors' virtual ADC solutions require reboot of virtual instances before new
resources are available, and each instance must be manually configured before
being ready for further configuration. vCMP allows virtual instances full access to
new network interfaces, VLANs, and even entirely new resource blades instantly and
without interruption.
Flexible allocation allows administrators to designate CPU resources (and blades on
chassis models) to guests upon creation. Dynamic scaling allows reallocation of
CPU resources, without disruption. This makes it possible to redistribute resources
to better align with the need for business agility in addressing growth and scale, as
well as support additional or new application delivery services that may require more
CPU resources. Administrators can size guests according to what's required for
each deployment—and modify when those requirements change.
Because the hypervisor is purpose-built, it can also be integrated into existing data
center orchestration solutions. This allows organizations to dynamically create and
provision new ADC instances as part of their existing orchestration solutions. Using
iControl, an F5 management control plane API, administrators can spin guests up
and down programmatically using a variety of cloud management platforms and
frameworks, as well as custom solutions. Programmatic control of ADC instances
enables elastic application network services and reduces operational overhead. This
integration is identical to, and utilizes the same methods as, integrating with
individual ADC devices (physical, virtual editions, or vCMP instances). In addition,
general-purpose hypervisors have very limited network options and can't support
the virtual MAC addresses required by VRRP (RFC 3768) and VLAN groups (proxy
ARP bridge). vCMP can act as any standard network device; it can act as a router, a
bridge, or a proxy ARP device as needed. This simply isn't possible with general-
purpose hypervisor use.
Conclusion
Today's consolidated data centers require flexibility and agility. CIOs and architects
are looking for solutions that provide the best return on investment despite rapidly
changing requirements and business needs. Yet traditional solutions for virtualizing
and consolidating hardware devices don't meet these requirements. Multi-tenancy
solutions fail to provide sufficient flexibility by not allowing isolation of instances, and
although they often reduce CapEx, they actually increase long-term OpEx. Virtual
