So, here you have the reason for your bad write performance with
Ceph. You have to carefully choose the journal SSDs, otherwise you
can be better even without SSDs... (yes, I made this very mistake too!)
What brand/model?
Yah I know :( Intel 530's initially, then Samsung 850 Pro. The 3700's
were out of our budget range for the size of our cluster.
Wasn't to happy with the direction Ceph is taking either, to me the
required hardware and complexity seems to be moving out of the range
of the small business setup and I'm not happy with the concept of them
moving it bare disk access (Bluestore).
Last Bluestore bare-HDD performance data seems quite good; but Bluestore
needs time to reach production-quality. I think the path is good and
with Proxmox Ceph Server management is very easy... ;)
What hardware requirements are out of the range of SBS?
