[SOLVED] Single Disk Advice

[Raymond Burns]

I just purchased a http://www.ebay.com/itm/300889121182?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649
Supermicro 6026TT-BTRF SuperServer with four X8DTT-F nodes
The issue is that there is no Hardware Raid onboard, and I need single additional PCI-e slot for Network Interface Cards.
I have 24 - 250gb disk. Everything I do will be on an OmniOS/Napp-IT NAS.
Should I follow the instructions for Proxmox 3.0 Software RAID post Installation, Proxmox 3.0 Software RAID on Debian Wheezy, or Single Disk installation?
I will be purchasing support soon after this cluster is up and running.
I most definitely need four NIC per server, and 6 NIC on Server Node 1.

NIC Per Node (6 Node Cluster)
eth0 - VPS (Public IP Provisioning)
eth1 - Local LAN
eth2 and eth3 - LACP Storage Network
eth4 (Node1 only) - Public Firewall
eth5 (Node1 only) - Private/Local Firewall

If you are saying single disk, how will I protect myself from the inevitable disk failure that will occur? (HA will be enabled for all Provisioned VPS through IPMI port)

For my specific situation, I will install Proxmox on each of the 12 Disk. Then I will use a single disk for operations. This helps me to comply with Subscription Requirements, so I can still get support.
There was a certain file that I needed to have backed up in order to load Proxmox easily, and all VM's on NAS. What is it? How do I go about backing it up?
My plan is to have that backed up file dynamic, but have three available Proxmox installations ready at any time to get loaded and restored.
Any other suggestions for an easier recovery?
