> If you talk to Dell/HP/other, they can advise you and sell you large storage appliances. Problem is, the larger appliances will only host 1 or 2 PB. That's nowhere near enough.

This is just incorrect.

If you talk to HPE, they should be quite happy to sell you the my employer's software (Qumulo) alongside their hardware. 10+ PB is definitely supported. (The HPE part is not required)

If you talk to Dell EMC, they will quite happily sell you their competing product, which is also quite capable of scaling beyond 1-2PB.

Most (all?) enterprise vendors will go well beyond 1-2PB.

Four years ago, one of the all flash vendors routinely advertised “well under a dollar a gigabyte”. Their prices have dropped dramatically since then, but the out of date numbers translate to “well under a million per PB”. That’s at the high end of performance with posix (nfs) or crash coherent (block) semantics. (Some also do S3, if that’s preferable for some reason)

With a 5 year depreciation cycle, those old machines were at << $16K / month per PB. Today’s all flash systems fit multiple PB per rack, and need less than one full time admin.

Hope that helps.

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.

Always fun stumbling across another Qumulon on here :)
