7. The Expert in Scale-Out Datacenters
Successful Deployments of 100K’s of Servers in
single instance
Over 1 Million servers sold to date
“Scale-Out” requires new thinking:
– Build-To-Order model… NOT “one-size-fit-all”.
– Optimize Packaging: Server, Cabinet, container
– Lowest power
– Innovative cooling

10. Cloud Trends

11. Where is the Cloud Going?
Greenpeace: Cloud Computing is growing
fast
It’s going Everywhere
Trends of cloud-computing:
– Growing usage
– Growing datacenters
– Growing electric demand
– On the bright side – growing awareness to
environment
We can help!... The question is “How?”
Company Confidential 11

12. How can we help reduce the impact?
Electricity is used to Power Up the datacenter
– Servers, Storage
– Backup Power equipment
– Cooling the infrastructure
We can help by optimize and lowering (or
eliminating) energy consumption in these aspects
– Use more efficient compute and storage
– Eliminate traditional power backup infrastructure
– Use free air cooling, free water cooling
Company Confidential 12

13. Why is Server Power so important?
“The cost of operating a server for 3 years is
higher then the cost of buying the server”
A typical server: $2,000, 250 Watts
Cost of power: $0.20 / KW-hour
Cost of 3-year electric use: ~$1,314
If PUE = 2.0… power+cooling: ~ $2,628
If PUE = 1.1… power+cooling: ~ $1,445
Company Confidential 13

14. Innovation: short servers
Reduces chassis length by 50%
Air needs to move less distance
– Less fans save power
– Slower fans save power
– Higher inlet air temperature save cooling save
power

16. Rackable Eco-Logical™ Chassis Design
15.5” / 40cm Long
5 fans x 4.5w =
22.5 Watts
Company Confidential 16

17. Chassis Design
If we can save 100w per server with smarter fan
and chassis design
1000 servers = ~ 100 kW difference
Company Confidential 17

18. How Else Can We Reduce Power Draw?
Use low power parts in the server
Eliminate unnecessary components
Use very efficient power supplies
Match Power Supply to server load
Cabinet-level power consolidation, monitoring,
capping
Optional DC-Power
