We are planning on testing our recent electrical resilience upgrade to the GN09 datacentre in the William Gates Building by running the datacentre from a mobile generator for a few minutes on Friday morning.
No disruption is expected; the UPS will power the datacentre for the very brief time that it takes our new automatic transfer switch to transfer the load to the generator supply. In the event of the generator failing, the UPS will pick up the load again whilst the load is transferred back to the mains electrical supply. We only anticipate disruption in the unlikely event of a UPS battery failure; however the UPS and its batteries have been serviced recently.
