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

Means to an end
‒ Addresses unsustainable model/finances
‒ Technology implementation but business implication
Combined with server virtualization
‒ 1+1=>2
‒ Research-based best-practice recommendations follow

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.

SOLVE THE TOP 6
ENTERPRISE
STORAGE ISSUES
MEET THE CHALLENGES OF
RAPID DATA GROWTH
18. ISSUE #1
EXPONENTIAL 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.
19. SOLUTION #1
STORAGE VIRTUALIZATION SIMPLIFIES MIGRATION
Single management interface
Move data across all tiers
Move data in the background
Applications continue running
Reduce time by 80%
20. ISSUE #2
LOW UTILIZATION OF EXISTING ASSETS
Ever-growing storage systems
Utilization below 50%
Half capacity is unused
New systems continue to be purchased
21. SOLUTION #2
STORAGE VIRTUALIZATION INCREASES CAPACITY UTILIZATION
Thin provisioning eliminates waste.
Tier data according to value.
Automate data placement.
Consolidate storage systems.
Reclaim 20-40% capacity.
