I used BL460c G6 and 7 with proxmox 1.x.
DL360 G8 with Proxmox 2.x and 3.X, No real problems with theses machines.
Apart for non-free firmware for the embedded NIC (Broadcom).

Here you can have a problem. I don't know if Proxmox kernel supports 
theses Flex NICs.

No problems with Smart Array controllers.
You can install tools from HP to configure it (hpacucli).

See below.

All dual/multi pathing concerns is not handeled by Proxmox.
But, you can handle it with the operating system (Debian Wheezy), with 

I was using e mutipathed FC SAN storage on EVA.
The multiple block devices created by different paths (it will be the 
same with iSCSI) where unified in on device in /dev/mapper/...
You should managed /etc/multipath.conf on all your nodes (I used puppet 
for that).

Packages for Debian where available here : 
I don't see wheezy on which Proxmox is built.
One useful tool was hpasm, for power/fan management.

Hope it can help.
