Small and medium businesses often run out of homes or small offices. Often, the server room is a room in a small office. Servers, especially those under load, tend to run quite hot and require significant cooling. How do you determine your cooling needs for your server room? Here is are some tips from MovinCool.com:
Check with the vendor
Most brand name server vendors provide thermal loads for their server models. Those figures take an average server load into account, so adjust those figures if server utilization is above or below the mean from the vendor. Now you have a rough estimate of the amount of BTU your server(s) generate.
Size the room
Use an A/C system sizing calculator to evaluate the kind of air conditioning you need for a room with that cubic capacity. Average calculators can take people and other equipment into account when present their figures.
Take potential growth into account. Will you need another server shortly? Do you have plans to increase the number of people in the office? These are just some of the questions you need to ask yourself before locking down your cooling requirement.
Lastly, get backup options in place for your server room air conditioner. Note that running servers will not cool sufficiently with fans or normal cooling devices when the A/C breaks down. One good option is to get a portable air conditioner to augment cooling during hotter months and to provide backup cooling during downtimes.
