Re: Looking for a problem to solve...
It might work for us here - Instead of buying expensive servers full of expensive SAS RAID controllers which you have to keep populating with expensive SAS disks, and even more expensive flash caches, you could buy a cheap ethernet enclosure - basically a glorified switch with integrated drive caddies - and run something like CEPH where you just keep adding more disks as required.
The magic only works if the kinetic enclosure + disks is cheaper than the dedicated SAN server machine of course.
I'd really like to see them build these things with POE RJ45 sockets on the back so they could just be slapped straight onto an existing switch - but that's probably not actually all that useful once you're outside of a testing environment because the cable management would get annoying :/
