Hi,

My datacenter will need to install Debian for me before I can install proxmox.
what instructions should I give them in regards to filesystems / partitioning.
The host will have a pair of 1tb SSD and will need to use software raid.

ie one big zfs raid1 pool?
 
Debian does not come with ZFS and therefore cannot be installed on a ZFS mirror. If you want a supported RAID1 setup then I think you need (instruct them) to install Debian on BTRFS (which is still a Technology Preview) with an ESP-partition on each drive (for proxmox-boot-tool).

EDIT: Alternatively, let them install Debian on one drive in any way they like and afterwards you manually create an ESP and bootable rpool on the other. Copy everything and change the configuration wherever needed (but I don't think there is a guide for this), boot from it and wipe the first drive to add it as a mirror.
