Hello Janne, so do you think we must move from 10Gbs to 40 or 100GBs to to make the most of nvme ? Thanks Ignazio Il giorno mer 20 mag 2020 alle ore 12:06 Janne Johansson < icepic.dz@gmail.com> ha scritto:

Hello All, We have 6 servers. Configuration for each server: 1 ssd for mon (only on three servers) 1 ssd 1.9 TB for db/wal 1 nvme 1.6 TB for db/wal 10 SAS hdd 3.6 TB for osd We decided to create a pool of 30 osd (5x6) with db/wal on ssd and a pool of 30 (5x6) osd with db/wal on nvme. So we create a vm on the pool with db.wal on ssd and a vm on the pool with db/wal on nvme. Fio performances are almost the same on both . What do you think about it ? I expect better performance on pool with db/wal on pci express nvme
Perhaps most of the time is lost talking over the network, making the small differences in how well ssd -vs- nvme perform not visible.
