If you know that your cooling is not covered by the UPS (and you *know* it, right? :), then your plan should be to start powering down servers immediately, starting with the least useful ones. That way, you can withstand a power outage that lasts only 15-30 minutes and not start frying your most expensive stuff; or keep on shutting down hardware and sustain a longer outage. Of course, the fine line is figuring out when to call an outage and start powering down. The same applies when your A/C fails and your sysadmins are not directly responsible for the A/C -- it generally takes a lot of time and physical room access to restart an A/C unit (they do not restart on their own), while it is usually easier to access servers remotely, so your sysadmin can shutdown stuff from home at 3am. -- olive _______________________________________________ Discuss mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
