Install Proxmox / CEPH / RAID controller

[boulate]

Hello !

I work for an association and we are migrating all our visualization systems to Proxmox and CEPH storage.

We have (relatively) old servers :
- 3 servers with HP P410i raid controller.
- 1 server with HP P400 raid controller.

I just wanted to know how you said to your controller to let CEPH (and proxmox) use each disk as a "single" disk.

I read people who said that put each disk in a separate "raid 0" (one raid0 for each disk) will let them act as a JBOD (passthrough) mode.

I just want to be sure that it will not be a problem for CEPH.

Do you know if this kind of configuration are possible with P400 and p410i raid controller ?

Thanks

It is said that you can turn the Raid Controller to HBA mode like this :

Haven't tried it myself but I'm planning to do this.
Using RAID0 is not recommended since it might decrease the performance.
