The decision for integration is Server Rack of 800 mm width

a greater packaging density, Server Rack 3,96 sqm
server racks must assure a
maximum of space efficiency.
This enables a maximum
computer density per m2 floor
space to be achieved.

25. Cooling System
For UNIQLE, only two SP54_Q racks with an integrated cooling
system have to be in-stalled to obtain 100 U.
For a comparable rack 800 mm wide with side-cooling
arrangement, you already need a third rack and a third
cooling arrangement.
UNIQLE consequently guarantees a higher computer
performance per sqm floor space and therefore absolute
space efficiency.
The UNIQLE cooling system is designed for useful cooling
capacities of up to 21 kW and is therefore an absolute high-
density cooling system.
The cooling capacity of the system is continuously variable
and is regulated to the specific conditions at any time by the
integrated rack control.

26. Cooling System
This means that at any moment only that degree of cooling is
provided that is needed for maintaining the defined optimal space
condition.
In comparison with static cooling systems, significant
savings in energy can consequently be registered.
This is additionally supported by low pressure losses of ≤ 0,5
bar in the water system.
UNIQLE thus ensures energy efficiency of a high order.
The heat exchange takes place in the rack, making
comprehensive additional installations in the computer room
unnecessary.

29. Rack Control
The Rack Management System (RMS) as an intelligent network
agent monitors all the environmental influences on server racks.
All the environmental parameters recorded are logically linked in
a freely programmable filter system.
As a reaction to certain environmental states, alarm messages
are automatically generated and/or switch operations triggered.
The RMS offers all sensors for the most diverse environmental
influences and at the same time controls their internal power
supply.
In conjunction with the cooling system, the Rack Management

50. DC Power Testimonials
“Rackable has allowed us to increase our global hardware
capacity by more than 50% without increasing our electricity
costs.” – CIO of Webex to Forbes Magazine, June 2006
“DC Power keeps the units considerably cooler within the chassis
themselves and saves us somewhere between 10 and 20 percent
over the AC-powered alternative." – Lead Engineer at University
of Florida to CNET, March 2006
By purchasing a DC-powered solution, eWEEK Labs believes
organizations will increase server reliability while lowering
monthly power costs. – eWeek Labs, March 2006
“We saw the power savings right away when we put in the
Rackable Systems servers.” – President of Spectrum to eWeek,
March 2006
“Using DC powered [servers], we're saving money on energy,
while receiving 20% more compute power in the same footprint."
– VP Technology of Right Media to Tech Target, Jan 2006
