HP iLO Shared Network Port

HP iLO (Integrated Lights Out board for HP servers – remote control et la)

Starting at firmware version 1.60 (after 30 Jul 2008) and on supported hardware:
DL360 G4, ML350 G5, ML370 G4, and DL380 G4 and G5

There’s a feature called “iLO Shared Network Port”

Which means you don’t need to cable up a separate iLO network! You can even set the iLO to use a different VLAN tag. This will come in very handy if your Colo charges for extra Ethernet ports (most do)

But with everything computer related… there are potential issues,

Some things to watch out for:

  • Set the iLO NIC to Auto-Negotiate to avoid it falling off the network when the server is powered down. Ref: HP Advisory: Integrated Lights-Out 2 (iLO 2) – Shared Network Port Set at 1000Mb May Not Respond When Server is Powered Off
  • VMware ESX server + iLO pass through
    There’s some chat in this forum that ESX server doesn’t support pass through of the iLO. I wouldn’t think the OS even comes into play here. Surely iLO pass through is done at the hardware level and the OS isn’t even aware of it. And beside I’m using a HP DL380 G5 running ESX 4.1 with the iLO set to Shared Network Port and it’s working fine. *knock* *knock* on wood.

    AH! “Pass Through” is a Windows Service called iLO Pass-through Service which allows the iLO console to be connected to a console Terminal Services Session and I gather from the terminology it means that it uses RDP all the way back to the client. Where as iLO Shared Network Port is a hardware based Ethernet port sharing feature.
