What happens when one of the PSU's fails catastrophically, pushing a big electrical surge through the hard disks, frying half of them?
I didn't see anything in here that discusses that eventuality? And when you have that many servers, it IS going to happen at some point...

- papercrane 17y agoIt's addressed in the section "A Backblaze Storage Pod is a Building Block" From the article: When you run a datacenter with thousands of hard drives, CPUs, motherboards, and power supplies, you are going to have hardware failures it’s irrefutable. Backblaze Storage Pods are building blocks upon which a larger system can be organized that doesn’t allow for a single point of failure.

- papercrane 17y agoIn the next section they say they have implemented the machine level redundancy. As for geographic redundancy I think the idea is that you use them for that. As in you backup your data locally and then send it to them as a redundant copy.
