…however Virtualization is no Silver Bullet either!
TypicalVirtualizationMisunderstandings3
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

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

WRONG!Your VM management SW is focused
only on balancing the IT resources (CPU, Memory, Storage)
