HP DL380 Gen10 PVE advice for Raid Controller

[mosesjohann]

Hi there,

Im configuring my first HPE-Server and need your help. We would like to use the standard Controller P408i-a in RAID10 Mode or HBA-Mode(is it working correctly?) - has anybody expierence if its working fine? If not, what would be better?

Second, apart from HP-specific, I'm thinking of using a separate set of disks for proxmox. We usually installed it all on one Volume - no problems so far but feels not so good, what do you think?

Thanks for your answers!

PVE 6.3 uses the Ubuntu 20.04 kernel, so if the controller is compatible with Ubuntu 20.04, it should also be compatible with PVE.
If you plan on using ZFS or Ceph, please use an HBA instead of a RAID controller [0].

What do you mean by 'using a separate set of disks for proxmox'?

Thanks for answering, I mean if proxmox should be installed on a seperate disk instead of direct on the same zfs volume where the vms run.

that's actually a good question. On the DL360 I have to put the boot on the smartcard to be able to use the hba mode. Is there anyway to do it during the installation?

That is up to you, but if you can it wouldn't hurt to separate the two.
If you are thinking about using ZFS then you really should not use a RAID controller. Get an HBA instead.
