Editor's Notes
- Note to Presenter: Present to customers and prospects to provide them with an overview of CLARiiON and advanced storage software that provides complementary functionality in VMware environments around resource flexibility, availability, and ease of use, to name a few. This presentation assumes that the audience is already familiar with key features of CLARiiON and VMware.
- Note to Presenter: The transformation of today’s data centers into “virtualized” data centers has now become the most important strategy for IT organizations, of all sizes, around the world. Two key factors are driving the epidemic adoption of virtualized data centers: The appeal of short-term CAPEX and OPEX (capital expenditure and operational expenditure) savings in today’s economy is clearly the leading factor. As companies get a taste of what virtualization can offer them in terms of flexibility, security, performance and simplified management, they begin to adopt it even faster and in more mission-critical environments. To adopt VMware virtualization quickly, and obtain all the benefits it has to offer, it needs to be run within an information infrastructure that has been designed for, and integrated with, VMware. This is exactly what EMC CLARiiON provides.
- Note to Presenter: View in Slide Show mode for animation. The key point to take away from these three reports is that for the past three years, EMC has finished far and away in first place in surveys conducted by three different analyst groups—IDC, Goldman Sachs, and Forrester Research—who asked respondents to identify their primary storage vendor for their virtualization environments. Although second, third, or fourth place vendors may have changed, the one common theme every year is that EMC finished first by a large margin. Note to Presenter : The actual report containing the middle chart is here (Exhibit 23): http://0301.netclime.net/1_5/138/2d8/298/CIO%20Survey%20-%20081102%20-%20GS.pdf
- Note to Presenter: To date, there are more than 300,000 CLARiiONs sold, which makes CLARiiON the most widely deployed midrange storage array in both virtual and physical environments. The cost and productivity savings of server virtualization are overwhelming. The bottom line is that the CLARiiON CX4 series provides a breakthrough architecture and industry-leading innovation in the areas of connectivity, scale, performance, storage administration, and energy efficiency. The CLARiiON CX4 series is designed to deliver high levels of scale, reliability, ease of use, and affordability—and all this is available in a range of choices to address many IT requirements. These requirements become essential in VMware environments, as they relate to how the storage software will ultimately function. Because the CLARiiON CX4 series is the only midrange storage platform that can successfully meet these requirements for VMware environments, more customers have chosen CLARiiON for VMware than any other networked storage array.
- Note to Presenter: “Virtual SMP “on the slide graphic is VMware Virtual Symmetric Multi-Processing. “VMFS” is VMware vStorage Virtual Machine File System. CLARiiON CX4 is optimized for VMware environments. CLARiiON’s full integration with VMware extends the value of virtualized server environments through… Shared storage: CLARiiON CX4 delivers the highest levels of reliability and availability required for VMware environments. With the expandable connectivity options of UltraFlex technology, Flash drive support, and twice the performance and scale, customers can take advantage of CLARiiON CX4 while leveraging VMware VMotion capabilities. Resource management: CLARiiON-integrated Navisphere Quality of Service Manager with VMware Distributed Resource Scheduler (DRS) provides end-to-end application service-level management from the virtual server to CLARiiON storage. Backup and recovery: CLARiiON CX4 and VMware Consolidated Backup (VCB) make backup-to-disk more affordable and energy efficient using drive Spin Down with low power SATA II drives in VMware environments. Replication: You can leverage VMware vCenter Site Recovery Manager using RecoverPoint or MirrorView/S software to simplify and automate disaster recovery setup, failover, failback, and testing, and ensure the proper execution and management of recovery plans.
- Now we’ll discuss shared storage.
- The CLARiiON CX4 is focused on making the entire installation, deployment, and storage management process easier. In virtualized server environments, this becomes paramount. Since users can deploy a new server in seconds, storage should be able to be deployed with the same efficiency as well. By combining Fibre Channel and iSCSI in the same storage array, deployment efficiency can easily be addressed. The CLARiiON CX4 can be deployed as a Fibre Channel SAN solution, as an iSCSI SAN solution, or a combination of the two. Fibre Channel is ideally suited for decision-support systems, backup-to-disk, and other streaming-media applications since these applications can leverage the extra bandwidth provided by Fibre Channel connections. Keep in mind that application performance is only one factor that will need to be weighed, along with the existing infrastructure, budget, and staff skill set. If you have not already deployed a Fibre Channel SAN, the CLARiiON CX4 series enables you to consolidate your application storage via iSCSI connectivity. This offers all the benefits of storage consolidation and allows you to leverage your existing IP network and hardware for SAN connectivity. At the same time, the Fibre Channel connectivity is there if or when you need it.
- EMC CLARiiON: выбор заказчиков для VMware Июль 2009 Even in virtualized environments, your application’s availability is only as good as the storage on which it ultimately resides. CLARiiON CX4 is built on the proven CLARiiON CX3 UltraScale series that has been tracking at Five 9s availability since its introduction in May 2006. This industry-leading availability is made possible through architecture, process, and software enhancements over the previous generation of CLARiiON systems.
- EMC CLARiiON: выбор заказчиков для VMware Июль 2009 Hyper-consolidation of virtual machines can lead to complex storage architectures. Mapping dozens of LUNs accessed by hundreds or thousands of VMs to channels is a laborious and complex job. Further, as virtual machines move around in the cluster, the I/O loads on the channel can change significantly. EMC’s industry-leading PowerPath/VE significantly reduces the effort required to set up the SAN environment. Let’s take a closer look at how PowerPath optimizes dynamic virtual environments. Note to Presenter: Click now in Slide Show mode for animation. Native multipathing products provide single channel failover only and require the Administrator to manually load-balance I/O-intensive VMs to maintain performance and avoid impact on other VMs in the environment. This requirement is in addition to the complexity of mapping active/standby channels for hundreds or thousands of virtual machines, let alone the use of VM mobility tools. With only one active and one standby channel per port, a failure in the active channel could quickly cause the standby to become overloaded with I/O when using a native pathing product. Note to Presenter: Click now in Slide Show mode for animation. In comparison, PowerPath/VE simplifies channel management in VMware and Microsoft Hyper-V virtual environments by leveraging all channels simultaneously for load balancing and failover. Additionally, PowerPath constantly adjusts I/O path usage and changes in I/O loads from virtual machines to optimize resource utilization. This results in predictable performance levels. Unlike the native product, PowerPath avoids overloaded channels as I/O load is automatically rebalanced across all other channels, minimizing impact and keeping applications online.
- EMC CLARiiON: выбор заказчиков для VMware Июль 2009 EMC is also incorporating an added level of automation to make it even easier for customers to manage their tiered storage environments. EMC calls this new capability FAST, which stands for Fully Automated Storage Tiering. This means full automation, with self-management that can automate the movement and placement of data based on changing needs. Here’s a typical tiered storage system with Flash, Fibre Channel, and SATA drives. Note to Presenter: Click now in Slide Show mode for animation. With FAST, you can use the latest disk technology in a way that automatically, and without your intervention, places, moves, and optimizes your data among these tiers of storage, all based on your changing needs. Flash drives are, in fact, revolutionizing the storage industry. FAST will enable many more customers to take advantage of Flash drives, thereby accelerating the transition to this advanced technology. FAST optimizes performance and cost through automation. It is a high-end capability that only EMC offers.
- Now let’s talk about CLARiiON capabilities that simplify resource management in a VMware environment.
- EMC CLARiiON: выбор заказчиков для VMware Июль 2009 Today, one of the major challenges facing users in virtual environments is a management complexity gap. Storage Administrators have access to detailed information on the array, but lack visibility into how the virtual server is configured and which virtual machines are consuming what for storage resources. VMware Administrators, on the other hand, can see the details of the virtual server environment and virtual machines, but lack visibility into the array. What’s needed here are more tools that automate management, discovery, and reporting and make it easy for both administrators to manage and report on who is using what, when, and where.
- EMC CLARiiON: выбор заказчиков для VMware Июль 2009 To help address this, EMC is introducing virtualization-aware Navisphere Manager for CLARiiON CX4 systems. Navisphere’s “virtualization-aware” capabilities deliver simple automation to enable end-to-end virtual-to-physical mapping of physical storage and servers, as well as ESX servers and the virtual machines that reside on them. Through new advanced Navisphere search capabilities, users can quickly identify a particular virtual machine and ensure that the appropriate amount of storage is allocated to it. In addition, a future version of this Navisphere functionality will deliver Microsoft Hyper-V management integration. The ability to automate management and discovery of virtual environments from the array is a unique capability for CLARiiON and demonstrates EMC’s commitment to helping users maximize the value of their storage infrastructure.
- So let’s look at the impact of virtualization-aware Navisphere Manager. Given the changing nature of a virtual environment, discovery and reporting can be a painstaking task. A medium-sized environment with 100 virtual machines on 10 ESX servers would require a user to step through 200 screens and record information manually to build a spreadsheet for reporting. This task takes hours to complete, and any change requires that the same steps be repeated to update the data. Note to Presenter: Click now in Slide Show mode for animation. With virtualization-aware Navisphere, the discovery and reporting process is automated, which allows users to export a complete report of their VMware environment with only two screens and no manual transfer of data. This process only take seconds, resulting in more productivity and significant time savings for the end user.
- In addition to virtualization-aware storage management tools such as Navisphere and Ionix ControlCenter, there are “plug-in” capabilities to make VMware vCenter Server EMC storage aware. In Q2 2009, EMC delivered the plug-in for VMware vCenter Server to provide integrated views of storage use, configurations, and checks for best practice settings for all EMC storage environment. Through vCenter Server, these Administrators are now be able to identify a specific LUN that is tied to a specific virtual machine. Be aware that this is a capability that most major storage vendors support today. Again, what is unique is that EMC provides users with a range of options to simplify management of a virtual environment, and that the capabilities being delivered through Navisphere are unique to EMC. Together with the Storage Viewer plug-in, this represents the first time that VMware and Storage Administrators are able to have complementary views into the storage and virtual server environments. Note to Presenter : White paper on slide can be found here on Powerlink: http://powerlink.emc.com/km/live1/en_US/Offering_Technical/White_Paper/h6155-using-emc-storage-view-for-virtual-infrastructure-wp.pdf
- EMC CLARiiON: выбор заказчиков для VMware Июль 2009 Service-level management, with the ability to tier your virtual machines, brings about another consideration when choosing storage solutions for virtualized environments. Not all virtual machines are created equal, and they have different service levels associated with their end users. CLARiiON has a powerful software application called the Navisphere Quality of Service Manager. This application is the only storage software capable of providing the granular LUN-by-LUN, service-level management that is required for virtualized environments. VMware’s quality-of-service functionality, VMware Distributed Resource Scheduler, monitors utilization across resource pools and intelligently allocates available resources among the virtual machines based on pre-defined rules that reflect business needs and changing priorities. When implemented together, Navisphere Quality of Service Manager and VMware Distributed Resource Scheduler will provide users with best-of-breed, end-to-end, policy-based application service-level management for their entire information infrastructure. The power of virtualization lies in the ability to provide solid service level agreement management.
- Let’s take a closer look at how Navisphere Quality of Service Manager and VMware DRS work in the same environment. Before Navisphere Quality of Service Manager, every application running on the virtual machine receives the same I/O treatment from an array-performance perspective. Note to Presenter: Click now in Slide Show mode for animation. With VMware DRS, as resources are needed from a higher priority application on the VMware ESX server, more of the virtual resource pool is provided to the virtual machine. With Navisphere Quality of Service Manager, the LUN associated with that same application can be combined in a policy that provides a performance goal, providing the right level of back-end array performance. By allocating more ESX server resources and array performance to support the highest priority application, an end-to-end service level is achieved.
- EMC CLARiiON: выбор заказчиков для VMware Июль 2009 Note to Presenter: View in Slide Show mode for animation. Due to the dynamic nature of VMware environments, resource flexibility is a major deployment requirement for any virtualized server environment. With CLARiiON CX4, you can provision your virtual infrastructure using CLARiiON Virtual Provisioning technology and grow your storage capacity on demand. CLARiiON Virtual Provisioning technology simplifies provisioning by allowing you to logically provision what you need for the future, but buy only what you need today. Deferring the capacity purchase saves you up-front cost, energy, floor space, and much more. VMware vStorage Virtual Machine File System (VMFS) has some useful characteristics that makes it thin friendly. VMFS does not write all of its metadata to disks on creation. VMFS formats and uses the reserved area for metadata as requirements arise.
- Note to Presenter: View in Slide Show mode for animation. With the CLARiiON CX4 series, users have the capability to mix a wider variety of drive types within a single frame. This functionality to mix SATA, low power SATA, Fibre Channel, and Flash drives in a single frame complements the economics found only with server virtualization. Virtual LUNs make possible the ability to tier virtual machines within the system—between drive types, online, and nondisruptively. The resource flexibility to move virtual machines within the array, based on the application performance requirements, is now possible. In the event that a virtual machine becomes less critical, Virtual LUNs can be used to migrate information. This type of migration may happen at different points of the business cycle. For example, at the end of a quarter, when additional virtual machine performance is needed for mission-critical data processing applications, the virtual machines can be migrated from ATA to Fibre Channel drives using Virtual LUN technology. Virtual LUNs can also be used when reconfiguring the system layout or adding additional capacity. This technology makes CLARiiON one of the most flexible midrange networked storage systems, allowing you to manage and change the system configuration as your VMware environment changes and grows.
- EMC CLARiiON: выбор заказчиков для VMware Июль 2009 Note to Presenter: View in Slide Show mode for animation. MetaLUNs are created when a single LUN is expanded via several methods—concatenation, striping, or both. When virtual machines require additional capacity, users easily provide additional capacity to their application with metaLUN technology through CLARiiON’s intuitive management interface: Navisphere Manager. The real-time LUN expansion also supports the creation of new virtual machines in real time. And with the new capacity immediately available to the VMware ESX server, no reboot is necessary, making this functionality imperceptible to the host application. Both raw device mapping and vStorage VMFS are supported with metaLUNs, and users can leverage this key technology to make efficient use of their storage resources in a VMware environment. EMC also offers users the best practices needed to implement metaLUNs in dynamic VMware deployments.
- Now let’s talk about backup and recovery.
- EMC CLARiiON: выбор заказчиков для VMware Июль 2009 Traditionally, servers have excess physical resources that could be used for backup processing ( i.e., servers that processed data during the day, and could be backed up at night without impacting production. With VMware, multiple virtual machines are put on servers so that processes run around the clock to reduce or eliminate the spare resources. Customers’ initial deployments of VMware will be able to manage backup in traditional ways. As they add more virtualized servers and get better at “packing in” their servers to gain maximum efficiency and cost savings, it will become difficult to execute backups successfully without impacting production workloads. Customers want to be able to manage their backups successfully before they are faced with data loss on a business-sensitive application because they chose to virtualize it. Because multiple VMs are loaded on a single physical server, the amount of data per physical server is much greater in the virtualized data center, therefore there is much more data to be backed up. Due to the nature of VMs, each containing a copy of the operating system ( i.e., Microsoft Windows), there is a high amount of redundant data in each VM. Avamar is a great solution for managing backups of VMware environments. A Windows VM will be in the range of 20 GB with about 90 percent redundant data. So an ESX server with 20 VMs would require 200 GB of space to perform a full backup, but Avamar would require only 40 GB of backup space. Since the backup process moves only 10 percent of the backup image and Avamar is using backup-to-disk technology, backups and restores will require significantly less time. Because of the backup resource issue, customers may choose to not fully populate their ESX servers with VMs so they have spare resources available for backup processing. With Avamar, customers can load their servers more heavily, which results in higher consolidation and successful execution of their backup strategy.
- EMC CLARiiON: выбор заказчиков для VMware Июль 2009 Note to Presenter: Qualification of specific application use cases for disk Spin Down is underway. You'll hear more about specific use cases and applications that EMC has qualified for deployment later in Q3 2009. CLARiiON’s built-in disk drive Spin Down on the CLARiiON CX4 is a capability that has existed on the EMC Disk Library since 2008. Spin Down allows the array to power down inactive disks and is managed via a “set-it-and-forget-it” policy. When in use, it will automatically stop the rotation of all drives within a RAID group that has been idle with zero I/O activity for 30 minutes. The drives remain powered up and online and will spin back up when a "first I/O" request is received. It takes approximately 15 to 16 seconds for the disks to spin up once I/O has started to a RAID group.
- EMC CLARiiON: выбор заказчиков для VMware Июль 2009 One common use case where Spin Down is applicable is in test and development environments. In fact, 80 percent of today’s VMware users have it deployed in their test and development environments. Consider an example where a Developer spends Friday performing tests using a CLARiiON for storage. The array is fully powered up and all drives are active as tests are run. At the end of the day, the Developer wants to run additional test runs before leaving. The test runs take three hours to complete, but there are another 59 hours until Monday morning when the Developer will return. With Spin Down, 30 minutes after the tests complete, the drives will power down, conserving power during the time when there is no activity on the array, saving 82 percent of the associated energy costs. It’s important to note that this test case is applicable to VMware environments that deploy raw device mapping, but not VMware vStorage VMFS.
- EMC Replication Manager is designed for ease of use through the following: Auto-discovery of applications, their associated storage, and the replication technology available; vStorage VMFS data stores, virtual machines, and their replication configuration during each replica cycle. Intelligence to place applications in the proper state for application-consistent replicas, such as VMware snapshots for vStorage VMFS data stores, online hot backup mode for Oracle, and VMware View for SQL Server. Instant recovery back to production application data for Microsoft Exchange, SQL Server, and Oracle running on virtual machines using VMDKs (virtual disks), physical RDM, or Microsoft iSCSI initiator-discovered disks. For vStorage VMFS containing virtual machines, create replicas for backup and instant restore through Replication Manager or perform a simple restore via VMware vCenter Server of a single virtual machine from a mounted replica created by Replication Manager. Additionally, you have flexible scheduling options to create recurring replication jobs or run one job ad hoc. You also have the ability to run pre- and post-processing scripts as well as begin a backup job, all within the Replication Manager replication job. You can mount replicas back to the production host to an alternate host. Additionally, Replication Manager will automatically expire old replicas based on the specified retention policies of each replication job. With the built-in automation, application intelligence, and flexibility of Replication Manager, protecting your VMware virtual infrastructure is a seamless alternative to scripting.
- Now let’s discuss replication with CLARiiON.
- EMC CLARiiON: выбор заказчиков для VMware Июль 2009 RecoverPoint is a product family for local and remote data protection, replication, and disaster recovery. It provides faster recovery and makes more cost-effective use of leased lines than array-based and application-based alternatives. The RecoverPoint family is comprised of two core products: RecoverPoint and RecoverPoint/SE. RecoverPoint CDP (continuous data protection) is local data protection; it provides local synchronous replication between LUNs that reside in one or more arrays at the same site. RecoverPoint CRR (continuous remote replication) is remote replication; it provides remote synchronous or asynchronous replication between two sites for LUNs that reside in one or more arrays. CRR dynamically switches between synchronous and asynchronous replication based on customer policy for performance and latency. Both RecoverPoint CDP and RecoverPoint CRR feature bi-directional replication and any-point-in-time recovery, which allows the target LUNs to be rolled back to a previous point in time and used for read/write operations without affecting the ongoing replication or data protection. Together, both CDP and CRR provide CLR (concurrent local and remote) protection of the same data volume. Additionally, CRR comes with integrated WAN bandwidth reduction that uses unique data reduction techniques and data compression algorithms to minimize and optimize network resource utilization by five to 10 times. The entry-point product is RecoverPoint/SE, which is designed for the homogenous CLARiiON market characterized by midsize enterprises. RecoverPoint/SE supports two RecoverPoint appliances in each site and has five models that support up to 32 TB of replicated data. RecoverPoint/SE is limited to replicating locally or remotely between Windows environments for CLARiiON arrays (including the AX4-5, CX4, CX3, and CX). In addition to Microsoft Windows, it can also support other qualified operating environments such as Linux, OpenVMS, Solaris, and VMware ESX server environments attached to a CLARiiON CX4 or CX3 array using the CLARiiON-based RecoverPoint splitter. RecoverPoint is the full-featured product and is best suited for high-end commercial through enterprise companies. It starts with two RecoverPoint appliances at each site and can grow to eight appliances per site. Capacity is licensed in 1 TB increments, and scales up to 150 TB per cluster. RecoverPoint offers advanced features such as support for intelligent fabric switches, replication across heterogeneous storage arrays, built-in bandwidth optimization, and data compression. RecoverPoint provides local protection using CDP technology, which captures every write and saves it in a history journal. It also provides CRR, using near-CDP technology that transfers significant writes, based on an application’s recovery point and recovery time objectives (RPOs/RTOs), to a remote site where they are saved in a history journal. The data recovery can be performed locally and/or remotely by rewinding the target volumes—think TiVo for storage—back to a selected point in time by using earlier versions of data saved in the journal. RecoverPoint/SE can be upgraded to RecoverPoint simply by purchasing an upgrade license and installing the new software license key. This enables you to upgrade to RecoverPoint without the loss of data protection or recovery capabilities.
- EMC CLARiiON: выбор заказчиков для VMware Июль 2009 Let’s take a closer look at RecoverPoint integration with vCenter Server. Using the RecoverPoint GUI, users can now easily view configuration and protection details on VMs, making it easy to identify unprotected VMs with LUNs and data stores. It also provides proactive notification and alerts if the state of a virtual machine changes from being protected to partially or fully unprotected. This capability is also unique to RecoverPoint, making it the only data protection solution that delivers integration with VMware vCenter Server to enable easier, automated VMware replication management. In addition, users now have a single interface to manage their replicated storage for virtualized and physical servers.
