Hi.

Will be setting up proxmox (first time) soon for a homelab with TrueNASbeing one of the first VMs being created.

Was wondering what the ideal disk layout would be given the following drives:

  • 5x 1TB SSD (SATA)
  • 5x 8 TB HDD (SATA)
Does it make sense to keep all the SSDs for proxmox and if a VM needs faster storage just allocate it from there or should I make a fast (3x SSD) and slow storage pool in Truenas.

Typical homelab stuff(media, backups, remote access, etc)

thx!
 
with TrueNASbeing one of the first VMs being created.

I highly recommend to PCI-passthrough a controller to that VM. Everything else is... suboptimal.

On PVE the VMs should live on SSD. Use as many SSDs as you can connect and just create a single ZFS pool as a "striped mirror" (~Raid10), so either use two or four SSDs. As long as you dos this already during initial installation each SSD will be bootable.

While separating OS from VMs is still a good idea nowadays for several reasons, for a Homelab with a limited number of disks it is fine to have a single pool - in my opinion.

Make sure to use "Enterprise Class" SSDs.

I would still say in 100% of cases with Proxmox, to definitely separate OS+Data, as the PVE ISO will wipe the target disk(s) for boot/root - and from what I read on a regular basis, Most People don't have a decent backup regimen and they will get into trouble.
