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 PS SSD are under SAS controller NVMe pcie Samsung PM1725B Best Regards Ignazio _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
