Cooling requirements for a data center with blade servers

We are planning a data center and was wondering if anyone could help with the amount of cooling we will need. We will have 100 blade servers in the data center along with other equipment We will have a raised floor as well.

You haven’t given enough information for a complete answer.

The number of “blade servers” isn’t as important in the calculation as is the total power drawn by the servers.

One KW of power for 1 hour (KwH) to a server generates approximately 3420 BTU/Hour of heat. If each “blade server” consumes 1 Kw, that’s 100 Kw of heat, or 342,000 BTU/Hour. That’s about 30 tons of cooling, <i>if</i> there were no losses (which there always are).

But due to losses, to actually get 30 tons of cooling to the equipment’s air intakes, you’ll need more. How much more depends on the design of the data center, its layout, and a complex analysis of airflow (both above and under the floor). And some for the “additional equipment” you made reference to. ;-)

    is that 100 blade chassis or 100 blade servers which would suggest 10 chassis? newer? older? There are technologies now that reduce the power usage and (hopefully) heat output. i haven't found blades to be very efficient for p*sqft ... you need to pull in a consultant with some experience to see your entire environment view; basic math can only go so far as mentioned previously you will need to analyze the airflow and go through in more detail on your specific power requirements.
