Can anyone recommend an expert Troubleshooting/Design firm that has extensive experience with Data Center specifici AC issues? We have a strange problem (probably with the airflow/vents/arrangements) which has machines in various locations dying due to heat, when the ambient temp isn't above 90. I've tried to find folks to deal with this and I get: a) Sales Rep's who want me to upgrade the entire system b) Folks who don't have Data Center experience but are willing to try c) Folks who claim to have experience but who either won't give ma references or who's reference don't say nice things about them I got a line on two places in California (we're in Michigan) as was desperate enough to call them but both seem to be out of business. Thanks in advance for any advice and/or recommendations. -- Andrew
my general approach has been to deploy relativly inexpensive temperature/humidity logging devices in places where we have "issues", and have our hvac folks rebalance some of our ac in that direction... in some cases moving hardware within racks, removing obstructions under our raised floors adding exhaust fan to racks has all helped with spot tempurature issuee... I can't really recomend a contracter, but I can recomend a temperature /humidity probe which might be a set in terms of establishing where the problem areass are... http://www.picotech.com/humidity.html connects to a serial port has linux and windows drivers requires no external power, costs $215. I either connect it to a convenient machine or hang it off a laptop and place it in the location I am concerned about. picotech also sells 8 channel thermocouple loggers which I haven't played with... regards joelja On Mon, 24 Sep 2001 ainman@umich.edu wrote:
