…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

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

WRONG!Your VM management SW is focused

only on balancing the IT resources (CPU, Memory, Storage)
