Analysis of the Advantages and Disadvantages of Wide-Temperature Server Rack Types

How big is a water cooled server rack?

In fact, there is a very wide variation of footprint for water-cooled server racks. Whereas the air-cooled rack power trends used the standard 19-in. rack footprint of 7.42 ft2 (0.72 m2) for all air-cooled power trends, the water-cooled racks varied in footprint from 6.78 to 48.20 ft2 (0.63 to 4.48 m2).

Are water cooled servers more popular than air cooled?

The geometry for the rack powers dis-played are for a 42 U, 19-in. (48.26 cm) standard rack with a depth of 43 in. (109.22 cm). Water-cooled servers are not nearly as prevalent as air-cooled servers. A method must be established that can best display some of the trends of water-cooled ITE.

Why is water cooled a good choice for a server?

Water has more than 3500 times the heat capacity of air. The ability of water to carry much larger amounts of heat per volume or mass offers tremendous advantages. Water-cooled servers have been around for more than a half a century. In the past, high-performance mainframes were often water-cooled and supplied as such by the ITE manufacturer.

What are the attributes of a water cooled server?

The attributes will be defined as follows: Flow rate—Volumetric fluid flow rate supported for safe, reliable opera-tion. When specifying a connector set, preferred installations promote maximum flow with minimal pressure loss. Typical ranges for water-cooled server applications may be 0.1 to 10 gpm (.38 to 31.85 L/m).
