Dallas, Here is my problem. Over 2 years ago we had a plan and budget to add an additional UPS to our environment. We had an aging 18kva (which will be decommissioned within a month) and a 75kva that was approx 10 years old at the time. We added a 150kva with plans to put an additional 150kva unit in when it came time to replace the 75kva. A generator was in the budget large enough to cover 2 150kva units and the AC cooling to the DC. Near completion of the project the generator fell out of the plan (but IT was not notified). As a result I have no backup power to the 150 or CRAC units. We were told the we would NEVER experience a power outage with our cogen plant. Since that time we have had 5 power outages, 2 that resulted in complete drain of battery power to the 150kva unit and extensive recovery time and work by the IT staff. The generator falls under the facilities guidelines. I am fighting to have a generator installed but running into a brick wall since the director of facilities is the person responsible for the purchase of the generator and also the same person responsible for the design and running of the cogen plant. Any ideas?

Depending on the proximity of the cogen to your datacenter, the capacity of the cogen, and the campus and datacenter electrical distribution design, abandoning the diesel generators might be a viable option for you, assuming you are not trying to alleviate downtime from all offsite causes (i.e. losing both grid power and natural gas at the same time).

If you do, do you still have generators backing up your DC UPS units? ***************************************** Ray Bruder Manager, Computer Operations Duquesne University DUsmall 600 Forbes Ave CTS, Rockwell Hall Pittsburgh, PA 15282 (412)396-5775 bruder () duq edu *****************************************
