Our dealer currently has a killer deal on HP LeftHand P4000 starter kits and we're considering purchasing one or two of them; however each chassis only has 2x 1GbE ethernet. This seems a bit light on to me. HP don't seem to offer anything but 10GbE upgrades.

Is it possible to install a 4-Port PCI-e NIC into these chassis and have it work with the software?

It may work with the software, but due to the way bonding works with LeftHand units, you're not going to see more than 1-Gigabit per LUN anyway. What do you think you need in terms of storage networking? If you care about per-LUN throughput, 10GbE is the right solution.

Since you'll be doing iSCSI MPIO, it's not as though you'd get a bigger bonded link by adding more interfaces. LeftHand scales by adding nodes.

Basically I know that the unit can pump out way more than the 1Gbps limit, and I was hoping to find a way to tap into additional bandwidth in the unit should we saturate the links it comes with. I guess I'm used to Dell hardware that has more network ports than you can poke a stick at. –  Mark Henderson Sep 25 '12 at 5:29
    
10GbE ;) Make the jump! –  ewwhite Sep 25 '12 at 5:34
    
Heh. We have some 10Gb equallogic gear, this budget doesn't quite extend that far though. –  Mark Henderson Sep 25 '12 at 12:23
