First installation - storage best practice for OS, VMs and Data in one server

Hi there-
this is my first Proxmox install, so maybe one of you could give me some guidance or point me to a good resource concerning storage organisation. I researched it but did not come to a full conclusion yet:

So I am about to get a decent server with at least 8x SAS/SATA in HBA mode (no hybrid/no hardware RAID) I want to run a few Windows VMs plus an FTP Server which will host a few TB of data. My setup could be the following:

- 2x small SSDs for Proxmox OS, ZFS in mirrored Vdevs
- 3x medium sized SSDs for the VMs and FTP storage, ZFS in RAIDZ1
- in a second step: new ZFS pool with SSDs or HDDs if the FTP server or other VMs filled up the space. This Volume should be useable by all VMs.
- also there will be a remote CIFS Volume/SMB share which I can use for backing up the Proxmox OS config and the VMs

What would you say from your experience - does it make sense to split it up like that? I read about separating Proxmox and the VMs. I just guess setting up another volume for storage only would not hurt ..
