CEPH disks on RAID 0 or not

[Spiros Pap]

HI all,

I am creating a ceph cluster that has SSD disks.
I would like to know if it is better create a RAID 0 for each disk (1 Vol for each disk) and then give this to Ceph or just give the native SAS disks.

The hardware is standard HPE DL380. I have this feeling that the Raid setups are more tested (the drivers) than the native sata/sas drivers (who runs a DL380 without RAID controller?).

Thanx,
Sp

Hi,

Ceph and also ZFS do not like Raid HW controller. So it is not recommended to use a Raid for the osd.

(who runs a DL380 without RAID controller?).

All peoples what use ceph and zfs.
