What’s the idea?
 Our approach is:
 A search for the IT infrastructure best efficiency
 Based on Lean and 6-Sigma industry methods
 A balance between “Do more with less” and “Assurance of future
sustainability”
 An on-going process, not a one time project
And it will
Show you how to optimize utilization of your IT assets
 Identify IT assets you can reclaim
Proactively make you aware of future IT resources organic

Our 2-phase approach to improve efficiency
 Identify servers under-utilized - Waste
 See how your IT is being used – Median
 Establish operational utilization levels – Goals
Continuous
Improvement
Based
on
LEAN
 Aim at power reserve targets - Improvement
6-Sigma
 Assess new situation – measure improvement

Recommendation
for improvement
 Servers that can be reclaimed
 Servers for consolidation - virtualization
 Servers over-utilized

Phase 2: Tuning for best utilization
 Principles
 Servers don’t run at 100% capacity and should not.
 You want to increase resource utilization close to the target operational levels
 And leave just enough power reserve to prevent resource contention
