Also match the capacity of the AC to the future output of the stuff in the room.
It's no good have a piss willy AC unit that cools the single server you have in the room, only for you to upgrade all the equipment in 6 months time and it can't keep pace. Have in the past used AC 2 units, one set at a degree higher than the other - the primary keep the temp down, if it fails the temp rises and the other kicks in. However do swap these functions over on a weekly basis..... -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Reeve Sent: 07 July 2003 17:06 To: [EMAIL PROTECTED] Subject: Re: [IMail Forum] OT: Server room Environment Totally agree with all respondents...another worthwhile standard, if you can afford the space, is to mount your rack systems on shelves with a 1U space between each unit. We have put in some very large digital video installations and the 1U gap has transformed the cooling in the 47U rack cabinets...not to mention the ease of changing units mounted on shelves. In one installation, due to an existing badly designed underfloor air conditioning, we also installed mesh doors instead of steel or glass, this again made a huge difference. A common mistake on large installations is the use of single, large UPS and Air conditioning units. Try and get the installers to provide multiple units so that any one unit can fail without jeopardising the computer system. Hope this helps.
