That depends on what contracts you have. You could have multiple of these cages in different locations. Also, 1 PB is only 56 large enterprise HDDs. So you just put storage into the cage, too.
But my point wasn't about how precisely the hardware is managed. My point was that with a large cloud, a mid-sized company has effectively NO SUPPORT. So anything that gives you more control is an improvement.
- dekhn 5y ago"1 pb is only 56 large enterprise hdds". umm, what happens when one fails? With large cloud my startup had excellent support. We negotiated a contract. That's how it works.
- fxtentacle 5y agoTypically people use RAID or ZFS to prevent data loss when a few hdds fail.
- dekhn 5y agoOK, so basically you're in a completely different class of expectations about how systems perform under disk loss and heavy load then me. A drive array is very different from large-scale cloud storage.
- fxtentacle 5y agoHard to say. My impression is: - A large ZFS pool of SSDs is much faster than any cloud storage. - Cloud storage failed much more often than the SSDs in our pool. - "Noisy neighbor" is an issue on the cloud
- qorrect 5y agoThis cracked me up. Thanks fxtentacle :D.
- dekhn 5y agoof course, the reason that's wrong is that if one drive fails you don't have a 56pb storage system, you have something smaller because of redundancy. That redundancy, and the performance that scales due to it, place cloud services in an entirely different class from on prem servers.
