A BUYER’S GUIDE TO STORAGE VIRTUALIZATION
AGENDA
What Is Storage Virtualization?
Alternative Approaches
Evaluating the Options
Real-world Benefits
Solve the Top Challenges
Storage Virtualization Results
Summary and Resources
STORAGE LANDSCAPE OVERVIEW
6
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
WHAT TO KNOW, WHAT TO LOOK FOR
7
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
VIRTUALIZATION MATURITY
8
Are you Building a Faster Horse or an Automobile?
WHAT IS STORAGE VIRTUALIZATION?
9
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

‘THE BIGGER TRUTH’ : ESG RECOMMENDATIONS
17
• Plan, plan, plan (SLAs and measurement).
• Size performance as well as capacity.
• Focus on training and best practices: to develop cross-discipline resources (people/tools/technology).
Basic
• Choose scalable (performance / capacity) platforms–more than “killer features”–to manage OPEX challenges.
• Focus on a) interoperability and b) integrating storage and VM replication.
Progressing
• Monitor and control and/or provision storage capacity growth.
• Experience does not always equal ease–plan for complex VM backup and recovery demands.

SOLVE THE TOP 6 ENTERPRISE STORAGE ISSUES MEET THE CHALLENGES OF RAPID DATA GROWTH
ISSUE #1
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.
EXPONENTIAL DATA GROWTH AND DISRUPTIVE STORAGE UPGRADES
SOLUTION #1
Single management interface
Move data across all tiers
Move data in the background
Applications continue running
Reduce time by 80%
STORAGE VIRTUALIZATION SIMPLIFIES MIGRATION
ISSUE #2
Ever-growing storage systems
Utilization below 50%
Half capacity is unused
New systems continue to be purchased
LOW UTILIZATION OF EXISTING ASSETS
SOLUTION #2
Thin provisioning eliminates waste.
Tier data according to value.
Automate data placement.
Consolidate storage systems.
Reclaim 20-40% capacity.
STORAGE VIRTUALIZATION INCREASES CAPACITY UTILIZATION
ISSUE #3
Multiple hosts, VMs, OS
Application and file data in petabytes
Multiple storage systems
Multiple management tools
Data center constraints
INCREASING MANAGEMENT COMPLEXITY AND FLAT BUDGETS
SOLUTION #3
Manage one virtual pool
One set of tools for all storage
30% more data per administrator
Speed up provisioning
STORAGE VIRTUALIZATION SIMPLIFIES MANAGEMENT
ISSUE #4
Cost of acquisition and support
License agreements
Increased floor space
Less budget for investment
INCREASING COSTS TO MANAGE STORAGE
Time
US$
SOLUTION #4
