We are opening a new facility in SF and are seriously considering the idea of by passing a large UPS (150-225KVA)altogether and relay on a generator 400-450KW with small UPSes on each rack. A UPS failure would be limited to a single rack, this way we could
We run a configuration similar to this, except we do failure per-row with one APC Symmetra supporting between 3 and 6 cabinets, depending on the projected load. In the past 2.5(?) years, we've had one controller failure that did not cause an outage. All the batteries are fine, though we have not run them to zero. It turned out to be a very clean install as far as conduit and cabling goes, we're very happy with it. -- nicholas harteau nrh () ikami com
