AL DíA: Hot in the Server Kitchen

Ok, lest you think this blog entry is about cooking, heat in the kitchen affecting wait staff, let me set you straight. In school districts, relying on storage closets as homes for expensive district-wide equipment (e.g. routers, switches, domain servers, virtualized machines on storage area networks (SANs)) isn't uncommon. These rooms can grow quite hot. This blog entry shares one approach to gauging heat.

Also common is how often the heat mounts in these rooms that were never designed to house heat generating equipment. In an old school district I became acquainted with, they kept the small windowless room setup with a standing fan, the kind you buy at Walmart, to pump air into the heated room housing over $500,000 in equipment. When I first saw it, I had to laugh and ask one assistant superintendent, "Why do you have this much equipment stored in a room with inadequate air conditioning and fire sprinklers in the ceiling?" The cost for fire suppression, a new building ($1M), would give any assistant superintendent of finance pause. The alternative, however, would have been much worse.

While that process was put in place (it took me 3 years of talk, careful plans and budget), I found myself looking around for a quick way to gauge temperatures in far flung WAN/LAN rooms.

This topic is the subject of one of my blog entries at TCEA TechNotes, Heat Sensitive: Server Room Temperature Gauges.
