…however Virtualization is no Silver Bullet either!

Typical Virtualization Misunderstandings 3

Virtualization is only the concern of an IT group! WRONG! Your virtualization installation will – like any IT equipment you bring into your DC – impact the physical infrastructure of your DC #1:

Facility Responsible for critical power and cooling supplies IT Responsible for IT operations Critical Power & Cooling Servers/Storage Units/Networking Equipment Compute Power/Storage Space/Network Access Applications/Services/Virtualization Building/Security/Physical Space The challenge is still here!

Virtualization impact on PUE and true energy savings Source: Schneider Electric WP118: Virtualization and Cloud Computing: Optimized Power, Cooling, and Management Maximizes Benefits

WRONG! Each VM started is associated with a cost of energy as a minimum Virtual Machines are free! #2:

Virtualization Sprawl Starting new virtual machines is so easy, but… – Who controls if a VM are ever used? – Who verifies if power and cooling requirements are still met? A VM running idle does consume energy! Each kW in a DC costs £10-15k to build and £1000 per year to run

VM impact on idle power Server power consumption 50% Server Idle Number of VMs 12345

WRONG! Your VM management SW is focused only on balancing the IT resources (CPU, Memory, Storage) My VM management SW helps me optimize my energy usage #3:

Scenario 1: Initial State VM Server #1: 200 Wh Server #2: 200 Wh Server #3: 210 Wh Server #4: 200 Wh Server #5: 200 Wh Server #6: 190 Wh Total Consumption: 1200 Wh

Scenario 2: 1 st consolidation Saving 25% Saving 25% VM Server #1: 230 Wh Server #2: 230 Wh Server #3: 230 Wh Server #4: 200 Wh Server #5: 0 Wh (off – restart 5 min) Server #6: 0 Wh (off – restart 5 min) Total Consumption: 890 Wh

Scenario 2: 2 nd consolidation VM Server #1: 240 Wh Server #2: 240 Wh Server #3: 240 Wh Server #4: 140 Wh (idle – real time ready) Server #5: 0 Wh (off – restart 5 min) Server #6: 0 Wh (off – restart 5 min) Saving 28% Saving 28% Total Consumption: 860 Wh

Dilemma: The Virtualization Jigsaw CPU Memory Storage Energy Cost DC Capacities

Its time to take off the blindfold…!

...and bridge the gap between Facility & IT
