2011 INDIA PARTNER SUMMIT
Virtualization wave 2Ranganath Krishna, Solutions specialist, Hitachi Data Systems
New Wave-New Order
• Year 2009 number of VMs overtook the number of physical servers shipped
• 97% of customers run VMware in production (VMware 2009)survey 2009)
• 55% of VMware customers run more than 50VMs (survey 2009)(survey 2009)
• VM density increasing from 10 to 20
Agendag
• What’s in there for you?What s in there for you?• Be ready for Wave 2
– Customer expectations from server consolidation has changed
• Hitachi integration formula in VMware environment • Reference architecture and case study
What’s in there for you?y
• Trusted advisor to the customer– Beyond the mundane server consolidation.
• Unique solution in the market– There is no need to fight competition.
• Demonstrable ROI.• Big services drag.
THE 2ND WAVE OF SERVER VIRTUALIZATION ADOPTION IS COMING
The Diffusion of InnovationSounds complicated, but it is simple
- Technology is adopted in wavesTh i i d f d ti
60-70%
- The main period of adoption, and therefore revenue, is in Wave 2

THE HITACHI ADVANTAGE –THE CONTROLLER
Did You Know? Dual controller systems are susceptible to ESX host workload imbalances, which require administrators to spend time manually diagnosing and mitigating load imbalances.
AMS 2000 Industry DifferentiatorHitachi Dynamic Load Balancing Controller: Virtually eliminates controller bottlenecks found in traditional
asymmetric controller designs
