Thanks for answer!

It's very interesting!

What is hardware you use for your the test cluster?
[Somnath] Three 256 TB SanDisk's JBOF (IF100) and 2 heads in front of that , so, total of 6 node cluster. FYI, each IF100 can support max 512 TB. Heads are with 128GB  RAM and Xeon 2690 V3 dual socket on each of the server.

You use only SSD or SSD+NVE?

[Somnath] For now, it is all SSDs.

Journal is located on the same SSD or not?

[Somnath] Yes, journal is on the same SSD.

What a plugin you use?

[Somnath] Cauchy_good jerasure.

You catch some bugs or strange things?

[Somnath] So far all is well :-)

Sorry for so many questions, but it's very interesting!
