Proxmox on T330 With Perc H330

[Michael S Ortega]

Hello guys, i have a server Dell poweredge T330 with perc H330 Raid controller, playing around with this controller i see its capable of running on HBA mode, id like to use proxmox on it with freenas, i know freenas recommended setup is passing through the whole controller, but want to ask if is good to use the controller on hba mode and present the disk to proxmox just as jbod. what do you guys thinnk, any recommendation will be highly appreciated.

setup (poweredge T330, 24GB RAM, PERC H330)
2ssd enterprise 600gb mirror for proxmox and vms
5x4tb nas drive for nas (freenas) with raidz2

Thanks in advanced. cheers

Hi,

generally, this controller does not have any cache that is good for this use case.
But passthrough single disks to FreeNAS will make problems because then you have the kernel cache between the disks and the FreeNAS.

I would recommend you attach the 2 SSD direct to the motherboard and passthrough the controller to FreeNas.

how would you approach this using the raid controller bios so we dont have to use freenas?

The T330 got 2 SATA port on the Mainboard.

yes it does, but i debating between using zfs or use the raid controller and create volumes to show to proxmox for storage and vms, and create LXC fileserver turnkey.

Alternatively, you can use ZFS on Proxmox if this controller has a real HBA mode.
install a Debian CT where you install OMV.

why that way? can i just install OMV on a vm using their iso file? what is the advantage of doing it through the CT?

Reducing the overhead and increase the disk speed.
Installing OMV in a VM is also possible and much easier to setup.

do i need to passthrough the whole controller with OMV?

Im actually looking for similar advices. I want a NAS for storing VMs and Shared storage (smb/nfs/afp)

i think of 2 scenarios :
- 1 . managing ZFS pools with proxmox and letting promox manage storage for VM and then creating a VM for OMV with a ""virtual disk" and managing shared files from OMV
- 2 . passthrought disks or sata controllers to the VM and letting OMV handling the disks entirely including VM Data disks

i think the issue with 1 is that ZFS will be invisible for OMV so basically i need to format the virtual disk to another file system and thats probably not recommanded .

But that give me direct access to VM data disks without the overhead of file sharing , am i right ?
