How often should a data center load test its back-up generators?
I used to work at a company with a huge diesel backup generator. A major storm came through and we lost power for almost two days. Fortunately we had the backup generator….except that it wouldn’t stay running when we needed it. How often should a data center load test its backup generators to ensure reliability and make sure the same thing doesn’t happen to them?
Quarterly testing should generally be sufficient. It should be actual load testing though, and not just a quick start up, shut down, mark it done test. It takes money and time to perform load testing, and some places cut corners.
