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.
