Hi,
define a raid-volume less than 2TB (e.g. 200-500GB) and install pve on this volume. After installation add the remaining storage as lvm-storage. That's it.

The DL380G5 runs out of the box. You should install the hp tools. You can download them as deb packages.
I setup RAID6 on this server as seen below.
>>Drive Write Cache: Disabled
Says write cache is disabled. Since I have battery shouldn't it be enabled? One of the servers I want to move to this box is currently on software RAID1 with two drives and I want to improve I/O. Will this be a step up?

I think this are two different things:
1. Memory build inside hard disk itself
2. Memory on the raid controller with BBU
so if you do enable DWC, BBU won't know for it and in case of power failure/etc you are risking for data loss.

If not the raidcontroller is very ugly, then of course yes. You got an much better readperformance (you can read from all disks at the same time) and for the write-performance the controller-cache is needed. If you also need a huge write-performnce go for raid-10.
Raid1 is only for redundancy, not for speed.
