Not without some engineering (ie baffles). I'll see where we are on getting that. -- Craig (from my mobile) Dan Olson <[email protected]> wrote: Now that I've started monitoring ipmi temperature sensors, I'm starting to see some systems that are reporting low temperature alarms. Most of the systems I've looked at alarm at 15 degrees C / 59F. The spec sheets for most of the servers, and the tape cartridges have the critical low operating temperature at 50F. I think we're currently very close to that at periods during the day, particularly in front of the tape library. I had a below 12 degree C alarm on tape library frame 2 at 3:11pm on the 8th.
From reading the ASHRE standard documents it looks like we're below spec for the low temp range for the 2004 (68F) and the 2008 (65F) version. Both of them have specific comments that tapes have more stringent class 1 temperature range requirements. It looks like we're at least 10 degrees F below the maximum inlet of 77F (2004) or 80F (2008) in the warmest cold aisles of the room.
It looks like we could use a 5 degree F bump on some of the cold aisle targets, does anyone know if it would be possible to get a higher setpoint in a few strategic areas? Mainly the cold aisle that runs in front of the tape library and in front of NMPDR. ---- Daniel Murphy-Olson Systems Administrator Mathematics & Computer Science Division Argonne National Laboratory 630-252-0055
