Hi, i did a lot of research and i am still wondering, where to install os (proxmox). We have ProLiant DL560 gen8 and gen9.
My options:
  1. micro SD card 32/64GB, not good because of lots of writings from proxmox
  2. usb 32/64GB
  3. 2x SAS disk 300/400GB, RAID1 through pci raid controller
  4. 2x SAS disk 300/400GB, through pci raid controller, but zraid1 in Proxmox
  5. 2x SSD disk 250/512GB, RAID1 through pci raid controller, probably not good because of lots of writings from proxmox
  6. 2x SSD disk 250/512GB, through pci raid controller, but zraid1 in Proxmox
  7. 2x NVME M2 disk 250GB, RAID1 through pci raid controller
  8. 2x NVME M2 disk 250GB, through pci raid controller, but zraid1 in Proxmox
  9. 2x NVME M2 disk 250GB, on pci, M2 NVME to PCIe Adapter 2x cards , but zraid1 in Proxmox

I would like to know pros/cons of this options, or if there are some other suggestions.
For vms we have SAN and fiber SW.
 
In one post, i found that: "PVE writes a lot (maybe amplified to 30GB per day on SSDs)"
Why would you go through PCI RAID controller? Isnt it better to use some disks (maybe ssds) and make array for "faster" vms?
