Hi Thomas,
thats a huge storage.
What I can say from my usecase - dont use Gluster directly if the files
are small. I dont know, if the file count matters, but if the files are
small (few KiB), Gluster takes ages to remove for example. Doing the
same in a VM with e.g. ext4 disk on the very same Gluster gives a big
speedup.
There are many options for a new Gluster volume, like Lindsay
mentioned.
And there are other options, like Ceph, OrangeFS.
How do you want to use the JBODs? I dont think you would use every
single drive as a brick... How are these connected to the servers?
Im only dealing with about 10TiB Gluster volumes, so by far not at your
planned level, but I really would like to see some results, if you go
for Gluster!
