RE: Effects of heat on Servers

["Paul Gale" <groups@xxxxxxx>]

1200 BTU is VERY low for this kind of kit (did you mean 12,000 BTU???).
Probably best to do the calcs in kW though - I recently had a 4kW air con
unit installed in my office as the window is South facing and I have
probably the same amount of heat generating kit in there.



If you like, I can get the calculation data from my Father (who designs
industrial AirCon systems) and let you know?

Paul.

Subject: [ukha_d] Effects of heat on Servers



This one is slightly OT, sorry.

A little while back we moved to some new offices. Our servers are now
located in a small room (6'x4'). In that room we've got 2 racks. Pretty
much populated with:

5 Servers

1 Voice Mail PC

8u of IP Phone Switch

2 x HP Procurve Switches#

A couple of large UPS's

Routers etc etc etc.



We've got a 1200 BTU aircon unit vented to the outside but its still
getting pretty warm in there. A certain member of our office is arguing
the cost of additional aircon as 'it will soon be winter'. I feel
CERTAIN that this heat is not good for the servers but I need to back it
up with hard facts. JUST TO PROVE A POINT ( I don't bare grudges
honest!) Can anyone confirm the effects of heat on servers? Even better
is their any web sources of info on the subject? Are there any
calculations for BTU's required per piece of equipment?



Many thanks in advance.



Rob
