HP iLO bandwith usage

Posted on 2011-04-20

When I connect via Remote Desktop (using HP passthru service) to my HP ML370 G6 via the dedicated iLO connection I was under the impression that this doesn't use bandwidth on the primary NIC - but when I do a speed test ( or a file copy from another remote server via a shared folder) I see the network bandwidth usage going over the primary NIC. The iLO has a separate IP and I am not using the Shared Port feature. So why is this happening? I thought the whole point of iLO was so that I'm not taking up bandwidth that other apps need.

    HI, could you please tell us the model of your server.

    because usually, the ilo it'a dedicate ethernet port, without the posibility of using on a OS

    It's HP ML370 G6 and yes, it has a dedicated iLO port.

    Accepted Solution

    The bandwidth that you are using between your computer and the HP server places zero load on the server's NICs, because you are accessing it via the ILO.

    But when you ask the server to conduct a speedtest, the server will correctly use one of it's NICs for that task.

    The iLO is meant as a means of access for server management, providing you access to the server whether the server is powered up or not.  It isn't meant to provide network connectivity for the server.  The normal network connectivity for the server will always use the server's NICs - not the iLO.

    iLO is designed for Remote Access traffic, e.g. mouse and screen data goes over the iLO port and that's it!

    when you are remotely viewing the server, any normal network traffic will transverse the normal network ports. e.g. your speed test.

    Hmm, that's a shame. So iLO is good, but not as useful as I thought. Thanks.
