I've checked what I could find on Qumulo. It is software that you run on top of regular servers, to form a storage cluster.

It seems to me you're only confirming my previous point, that you need to invest in complicated/expensive software to make the raw storage usable.

>>> Then you're going to have to handle "sharding" on top of the storage because there's no filesystem that can easily address 4 racks of disks. (Ceph/Lustre is another year long project for half a person).

There's no listed price on the website, you will need to call sales. Wouldn't be surprised if it started at 6 figures a year for a few servers.

It looks like it may not run on just any server, but may need certified server hardware from HP or Qumulo.
