Market Perspective
Datacenters becoming
exponentially more dense
kW per Rack
Datacenter refresh driven
by power/cooling/space
Energy cost is consuming
more budget and is harder
to ignore
Cost to Power Server Will Soon
Exceed Purchase Price
The divide between IT and
facilities is narrowing
Environmental impact, govt
awareness and corporate
initiatives on the rise
3
Today’s Model is Broken
Poor forecasting + low
flexibility = excess capacity
Over-provisioned Capacity
Typical datacenter: 3 years
excess server capacity
Servers consume >50% of
average power when idle
Inefficient Datacenter Design
Datacenters are outdated
and hugely inefficient
Cooling servers often
requires 2x the power
consumed
4
Datacenter Spend is on the Rise

Customer Example: Large manufacturer with 50k+ employees
Mainly HP DL585s with 16GB physical RAM
Many production workloads across multiple Oses: Java, Citrix, SQL Server, …
~60 VMs (1GB RAM each) per ESX Server
~60GB of aggregate virtual memory allocated
