Not strictly Linux related, but I thought I'd ask some like-minded people :) What should the target temperature of a server room / datacentre be? I've been tasked with improving the climate control of the server room here, and I have no idea really what I should be speccing.
For US$43 you can have a copy of "Thermal Guidelines for Data Processing Environments" from ASHRAE (1791 Tullie Circle NE, Atlanta, GA 30329) at <http://www.ashrae.org>. Manufacturers often have machine room or datacentre planning guides - Sun's is at <http://docs.sun.com/source/805-5863-13> . They recommend 22degC +/- 1degC and 48%RH +/- 3% . They've got some good stuff on monitoring, too. In my (limited) experience, actual temperature isn't the only issue. Redundancy is good. We once had a single external heat exchanger fan ice up (it was cold outside). This caused a machine room zone hotspot so fast that after less than 10 minutes 9 mainframes went down like a row of dominoes. jd -- John Daragon argv[0] limited john@xxxxxxxxxx Lambs Lawn Cottage, Staple Fitzpaine, Taunton TA3 5SL, UK (house) 01460 234537 (office) 01460 234068 (mobile) 07836 576127 (fax) 01460 234069 -- The Mailing List for the Devon & Cornwall LUG Mail majordomo@xxxxxxxxxxxx with "unsubscribe list" in the message body to unsubscribe.
