One of the biggest challenges related to blade servers in an existing data center is how to power and cool.  APC wrote a white paper (link below) that explains how to asses the options to best power and cool your blade environment. 

According to APC’s whitepaper, there are five basic approaches to cooling a blade server environment:

The white paper also goes into detail on how to select the type of cooling methods as well as some major considerations to review:

The whitepaper concludes with some cooling approaches that datacenters should not use:

• Reducing air temperature set-pion on the computer room A/C units to attempt to solve hot spots
• Replacing vented tiles in a raised floor with a tile that has less resistance
• Using fan trays installed in the top of racks
• Isolating racks away from rows in an open area on all sides
