 What Is Storage Virtualization?
 Alternative Approaches
 Evaluating the Options
 Real-world Benefits
 Solve the Top Challenges
 Storage Virtualization Results
 Summary and Resources

5. 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. 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

8. 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

RECOMMENDATIONS
• Plan, plan, plan (SLAs and measurement).
• Size performance as well as capacity.
Basic
• Focus on training and best practices: to develop cross-
discipline resources (people/tools/technology).
• Choose scalable (performance / capacity) platforms–more
Progressing 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.
