  2. 2. server and storage virtualization. Indeed, reinforcing this commitment, IBM providesformal and flexible support policies for IBM products running on or with VMware servervirtualization products.Storage – The Single Most Important Factor in Server VirtualizationStorage is the most important element in successful server virtualization projects. As thenumber of applications per server increases, the consolidation of once well-behavedand predictable I/O patterns creates huge demands on storage systems. Even simplesequential I/O streams essentially become totally random streams and storageinfrastructure that is not up to the task becomes a crippling bottleneck.Nonetheless, with proper, well-planned underlying storage resources, servervirtualization can deliver even greater resource consolidation, administrative efficiency,and cost savings while not only transforming data centers, but also the businesses thatthose data centers fuel. And, attaining these transformative results depends onenterprise-class storage to deliver the performance, availability, and flexibility to keep upwith the dynamic and consolidated nature of virtualized server environments.Key Customer Challenges for Server VirtualizationWe have identified four of the biggest challenges that customers face when consideringadvanced server virtualization using VMware vSphere: Application Resiliency In today’s always-on world, tier-1 applications must always be up, well performing, able to respond to changing demand patterns and tolerate infrastructure changes and disruptions. Of course, highly-available applications require the typical high availability (HA) storage features including fault tolerance, no single point(s) of failure, and non- disruptive upgrades and data migration. But the industry is evolving towards solutions that go beyond typical HA practices. Recovery times must be minutes and not hours; recovery points must be exactly where an application ended processing (application consistent). Moreover, ideally an HA solution should not require extensive specialized care, specialized staffing or complex procedures. Ultimately the evolution leads to continuously available applications and storage systems that support application resiliency must provide true data resiliency. Explosive Data Growth According to Reuters, “In any two days mankind creates as much online information as it created in the previous 30,000 years. By 2021, that same amount of information will be generated in less than an hour”. Nobody denies it anymore – coping with explosive data growth is a requisite for survival and business advantage. Storage system scalability is one key requirement for coping with explosive data growth, but there are many dimensions to data growth including storage capacity, performance, manageability, cost, asset life-cycle management and overall storage efficiency. What’s more, this growth must usually be accommodated without and increase in headcount and frequently budget.©2012 The Tod Point Group Page 2
  3. 3. Asset Optimization After providing infrastructure that addresses these first two challenges, the name of the game becomes asset optimization. The first objective is to drive asset utilization up to the highest levels possible and, thus, provide the highest return on assets. Server and storage virtualization improves asset utilization often by thirty percentage points or more. Storage virtualization can also extend asset life by way of over-subscription. The life of older, existing storage assets can also be significantly extended by virtualizing them behind newer assets. Moreover, an asset that can scale will typically have a longer life. Also, a versatile asset can reduce asset sprawl by simultaneously supporting many workloads and access protocols Further optimization is possible by putting the right data in the right place at the right time at the right price. Recent advances is automated storage tiering help balance cost and performance. What’s more, assets have finite lives and when they need to be retired there must be a way to seamlessly transition from old to new assets. In addition, discovering and tracking assets and their utilization promotes asset optimization planning. Also, spotting trends, managing disk space, detecting over utilized assets, etc., promotes application resilience. Lastly, another way to optimize storage assets is to reduce the amount of data stored or wasted and thereby avoid acquiring additional assets. Data reduction techniques include intelligent backups, space-efficient snapshots, data de- duplication, compression, archiving and policy-based file management. Easy to Manage The list of tasks that a VMware or storage administrator must accomplish is daunting. Managing growth, solving performance issues, provisioning storage, ensuring data is protected and restored all take time. As storage infrastructures become increasingly complex, managing those infrastructures should not become more complex. Most customers want a single pane of glass, a simple, helpful and intuitive GUI and integration with vSphere vCenter.VMware vSphere Integration and CertificationAs noted earlier, storage is the most important element in successful servervirtualization projects. Indeed, as virtual machine density increases, asset utilizationskyrockets to the point where common storage coordination, initialization, ormanagement functions (such as backup) can overwhelm a server. So, VMware hasworked with its storage partners to develop a set of APIs, known as vStorage APIs, tohelp offload critical coordination and many of the most resource-intensive functions toits partners’ arrays.VMware vSphere certification ensures that a vendor’s product has passed extensivetesting using test suites provided by VMware. Certification matrices are published byVMware and include the Storwize V7000.©2012 The Tod Point Group Page 3
  4. 4. The IBM Storwize V7000 Unified Solution – Enterprise-class Storage Solutions forvSphere in the Midrange MarketSpecifically designed for the mid-sized datacenter, IBM’s Storwize V7000 comes with arich set of storage optimization features – including an IBM software stack.Derived from other IBM storage solutions including the IBM SAN Volume Controller(SVC) which has been virtualizing storage since the year 2003 and the IBM DS8000storage system, the Storwize V7000 leverages their proven functionality to provideenterprise-class functions for the mid-range market.The V7000 also comes tightly integrated with two key IBM Tivoli management products,IBM Tivoli Storage FlashCopy Manager (FCM) and IBM Tivoli Storage ProductivityCenter (TPC) for Disk Select. It also integrates tightly with VMware vSphere. AdditionalIBM Tivoli products such as Tivoli Storage Manger for Virtual Environments (TSM VE)or TPC-for Replication are also available.Robust Data ProtectionFCM uses the copy services capabilities of Storwize V7000, FlashCopy, to create point-in-time snapshot copies. These are application aware copies of production data. Thiscopy is then retained on disk as backup allowing for a fast restore operation (Flashback).FCM also allows mounting the copy on an auxiliary server (backup server) as a logicalcopy. This copy (instead of the original data on the production server) is madeaccessible for further processing. This processing includes creating a tape backup orperforming backup verification functions (for example, a database verify utility).FCM is also integrated with the VMware vStorage API for Data Protection. FCM usesthis API to initiate a vSphere software snapshot of virtual machines and determineswhich LUN(s) are associated with these virtual machines. FCM then invokes hardwarecopy services to create a persistent snapshot copy of the LUN(s) that are hosting thevirtual machine’s datastore and vSphere snapshot.The benefits of this feature for vSphere are numerous. Hardware snapshots are fastand efficient and require no resource consumption on the host. Moreover, to improvestorage efficiency, data can be moved to TSM for long term retention and disasterrecovery. Data can also be de-duplicated when sent to TSM. For the utmost in speedand efficiency, FCM can restore individual virtual machines, volumes and LUNs.In environments where FCM is used with TSM, automatic backups by TSM can bescheduled. The backup can start immediately after the point-in-time copy is created, orat another time when resources are available to complete the backup request. If abackup to TSM fails, FCM can restart the backup after the cause of the failure iscorrected. In this case, data already committed to TSM is not re-sent. FCM can also usethis point-in-time copy to create a clone database with or without changing the name ofthe cloned database.Automated Storage TieringThe V7000 also ships with IBM’s Easy Tier automated sub-LUN storage tiering function.This no-charge function can optimize the use of solid state disks (SSDs) and hard disk©2012 The Tod Point Group Page 4
  5. 5. drives (HDDs) by maximizing performance gains while minimizing costs. Relocating just5% of data to SSDs with Easy Tier can reduce response time 78%. Small chunks ofdata can automatically percolate up or down a tier depending on its heat index.Easy Tier manages the proper placement of data between SSDs and HDDs on acontinuous basis. Its continuous workload monitoring capability dynamically determineswhether or not data chunks should be on an SSD or an HDD, and, as necessary,automatically moves these chunks non-disruptively from one tier to the otherComprehensive Resource ManagementTPC is a robust storage resource management tool that provides topology visualization(SAN and disk), performance monitoring, capacity management, and comprehensivedisaster recovery assistance. TPC can provide near-real-time performance statistics oranalyze historical data. Combined with the Storwize V7000’s real-time reportingperformance troubleshooting is a wiz.Scale Up or Scale Out or BothIBM recently announced a clustering capability for Storwize V7000 that essentiallydoubles the capacity and performance. So, customers can scale up by adding disks to asingle node or scale out by adding another node.Truly Unified Block and File.Also recently announced was the addition of file serving in addition to block serving – allwith a single unified interface. The value proposition of unified storage (multi protocoland multi functionality) is the flexibility and ability to adapt to different usage scenariosthat enable a storage system to take on more personalities. What this means is that bybeing able to support multiple interfaces and protocols along with different types ofmedia and functionality, a storage system becomes multifunctional. A multifunctionstorage system may be configured for on-line primary storage with good availability andperformance and for lower-cost, high-capacity storage in addition to being used asbackup target. In other scenarios, a multifunction device may be configured to perform asingle function with the idea of later redeploying it to use a different personality or modeof functionality.In addition, most experts recommend a mix of file and block servers for VMwareenvironments. File storage is easier to manage, but has a little more overhead andlatency. Block storage is faster, but more complex. And, the Storwize V7000 Unifiedscales up for file serving as it employs additional processing and does not interfere withprocessing resources needed for block servingWhat’s more, for file workloads, customers can optionally use IBM’s Active CloudEngine, which lowers storage costs by moving files transparently to the mostappropriate tier of storage, helps control storage growth by moving older files to tapeand deleting unwanted or expired files, improves data protection by identifyingcandidates for backup or disaster recovery and creates a more powerful and scalablestorage environment. In the future, it will provide automated file management andenable ubiquitous access to files from across the globe, reduce network costs and helpimprove application performance by distributing files closer to users,©2012 The Tod Point Group Page 5
  6. 6. Meeting Customer Challenges and MoreTable 1 (below) illustrates how this system squarely addresses customers’ topchallenges. Almost every feature of Storwize V7000 addresses all these challenges.Additionally, Storwize V7000’s unique architecture is particularly suited to servervirtualization. When provisioning storage for VMs, data can be striped across a largenumber of disks. This is called wide-striping and it has a proven history of providinghigh-performance in these demanding server virtualization environments. Moreover, asingle, non-clustered Storwize V7000 has been independently tested in mixed workloadenvironments with vSphere and has been shown to be able to support E-mail, database,web serving and backup workloads simultaneously with excellent performance andthroughput. In addition, the use of solid-state disks (SSD’s) with automated tieringsoftware, IBM’s Easy Tier, more than tripled the mixed I/O capacity of the V7000 andimproved response time for these workloads by as much as 43%. The paper discussingthe testing can be found here. SSD’s can also be used effectively for vSphere’s swapfiles which significantly benefits all workloads.ConclusionThe combination of VMware software and IBM Storwize V7000 offers significantadvantages for customers consolidating servers and storage to reduce costs andoptimize IT assets. A virtualized storage infrastructure with VMware and StorwizeV7000 can significantly improve administrator productivity, reduce performancebottlenecks, increase storage utilization and reduce the storage footprint.With the addition of unified block and file serving, active file management and clustering,Storwize V7000 has become one of the most versatile, scalable and highest performingstorage solutions in the mid-range market.©2012 The Tod Point Group Page 6
