The battery integration is quite interesting, although I'd bet they are using it for purposes other than "having to buy one big UPS."
One benefit I see to it is high availability, since the site UPS going out won't take down the servers, since they all have their own. Plus, I'd bet it makes the guys that work on the power buss sleep sounder at night, since its easier to work on without worrying about taking out the whole datacenter.
- jonah 18y agoSince they're running the PSUs near capacity. the batteries probably provide some additional headroom under heavy load spikes.
- nradov 18y agoYes, there have been a few publicized incidents at large hosting centers where the central UPS either failed or didn't kick in when it was supposed to. By putting the battery in the server it eliminates that single point of failure.
