  5. 5. AGENDA What Is Storage Virtualization? Alternative Approaches Evaluating the Options Real-world Benefits Solve the Top Challenges Storage Virtualization Results Summary and Resources
  6. 6. STORAGE LANDSCAPE OVERVIEW Storage doesn‟t matter! ‒ IOPS, apps and ops are not the point. Storage “tail” wagging the IT “dog”? ‒ Last bastion of awkwardness is “Ponzi storage” Major challenges: Scale and flexibility ‒ Change inevitable Industry consolidation and dynamics ‒ The converged, integrated, stacked, automated promise Is storage an anchor on server virtualization? ‒ Storage through the ESG Maturity Model phases 6
  7. 7. WHAT TO KNOW, WHAT TO LOOK FOR The „Assumption Gap‟ Why you even need to know (i.e. how we got here) 99% of the time a non virtualized storage environment = a sub optimal storage environment ‒ Close to an IT „no brainer‟ Look for – ‒ Heterogeneity ‒ Commitment ‒ Proof 7
  8. 8. VIRTUALIZATION MATURITYAre you Building a Faster Horse or an Automobile? 8
  9. 9. WHAT IS STORAGE VIRTUALIZATION? Technology as hope! ‒ Operational fluidity and utilization efficiency ‒ The foundation to balance [absolutely] escalating storage demands with [relatively] constrained resources Disassociates physical hardware from system usage ‒ Part of overall virtualization (servers) ‒ Can address „Ponzi storage‟ ‒ Not new or voodoo Should be on your „to do‟ list ESG‟s Server Virtualization Maturity Model 9

Basic • Focus on training and best practices: to develop cross- discipline resources (people/tools/technology). • Choose scalable (performance / capacity) platforms–moreProgressing than “killer features”–to manage OPEX challenges. • Focus on a) interoperability and b) integrating storage and VM replication. • Monitor and control and/or provision storage capacity Advanced growth. • Experience does not always equal ease–plan for complex VM backup and recovery demands. 17
  18. 18. SOLVE THE TOP 6ENTERPRISESTORAGE ISSUESMEET THE CHALLENGES OFRAPID DATA GROWTH
  19. 19. ISSUE #1EXPONENTIAL DATA GROWTH AND DISRUPTIVE STORAGE UPGRADES Data is growing at over 50% per year. Data migration is disruptive. ‒ Several hours per server Tiering data by value can lead to isolated silos. Managing data becomes more complex.
  20. 20. SOLUTION #1STORAGE VIRTUALIZATION SIMPLIFIES MIGRATION Single management interface Move data across all tiers Move data in the background Applications continue running Reduce time by 80%
  21. 21. ISSUE #2LOW UTILIZATION OF EXISTING ASSETS Ever-growing storage systems Utilization below 50% Half capacity is unused New systems continue to be purchased
  22. 22. SOLUTION #2STORAGE VIRTUALIZATION INCREASES CAPACITY UTILIZATION Thin provisioning eliminates waste. Tier data according to value. Automate data placement. Consolidate storage systems. Reclaim 20-40% capacity.
  23. 23. ISSUE #3INCREASING MANAGEMENT COMPLEXITY AND FLAT BUDGETS Multiple hosts, VMs, OS Application and file data in petabytes Multiple storage systems Multiple management tools Data center constraints
  24. 24. SOLUTION #3STORAGE VIRTUALIZATION SIMPLIFIES MANAGEMENT Manage one virtual pool One set of tools for all storage 30% more data per administrator Speed up provisioning
  25. 25. ISSUE #4INCREASING COSTS TO MANAGE STORAGE Cost of acquisition and support License agreements Increased floor space Less budget for investment US$ Time
  26. 26. SOLUTION #4STORAGE VIRTUALIZATION REDUCES CAPEX AND TCO Eliminate redundant licenses Consolidate more data Reduce power and cooling Defer future purchases Reduce labor costs Extend life of assets
  27. 27. ISSUE #5ENSURING SERVICE DELIVERY TO BUSINESS Access, availability, reliability Service level agreements Competing applications on network Difficulty in metering and reporting Consistency in response time
  28. 28. SOLUTION #5STORAGE VIRTUALIZATION ENABLES METERED SERVICES Logical partitioning Dedicated to each business line Central administration Service level assurance
  29. 29. ISSUE #6ACHIEVING COST-EFFECTIVE DATA RESILIENCE Increased focus on compliance Downtime intolerable Achieving mix of protection and investment Costly duplication of effort Application, local, remote
  30. 30. SOLUTION #6STORAGE VIRTUALIZATION ALLOWS ANY-TO-ANY REPLICATION Local replication among tiers Distance replication Any storage to any storage Same services available to all Standardization to lower licensing costs
  31. 31. WRAP UPSOLVE THE TOP 6 STORAGE PROBLEMS1. Simplify migration – up to 80% less time2. Increase utilization – up to 50%3. Simplify management – 30% more storage per person4. Reduce cost – 100% ROI in one year5. Ensure service delivery – match performance to cost6. Create data resilience – any storage at any distance For all the storage virtualized!
