Thread: Investigating use on HP Proliant DL380 R04

  1. #1

    Default Investigating use on HP Proliant DL380 R04


    I would like to run open-e iSCSI enterprise on two HP Proliant DL380R04 machines - one machine as active, second one as passive, with replication of 900GB of data. Data will be virtual machines accessed from 2 other Proliant servers running VMware Server.

    Specs for this machine are:

    Single Xeon 3.0Ghz
    SAS disk subsystem with smartarray controller (linux CCISS)
    1GB RAM

    A few questions I can't seem to answer:

    1) Is this machine supported as a whole?
    2) Is the hardware RAID supported? (I believe it is in the HW list)
    3) Can I monitor RAID status (good, degraded) in Open-E?
    4) Is the CPU sufficient for this use?
    5) Any advantage in adding RAM?
    6) *important* is the replication ready??

    Thanks for the feedback!

    ...and maybe a question that won't be answered...

    Is 1.7 replication based on DRBD?

    Your system specifications are adequate for the Xeon 3.0Ghz. Please download Demo-CD to further test the SAS Controller. Some of the SAS controllers that we support are below. A list will soon be listed on our web site - until then please wait for the list or test with Demo-CD. If over 10 or more hosts connected and the amount of activity - RAM is to cheap not to add another 1GB. HW RAID is supported and SW RAID as well (Please download the manual for a better understanding or download the Demo-CD). Monitoring is controlled by the controller for RAID status. Replication is currently not ready and no date has been set.

    Again Replication is currently not ready and no date has been set. To help others understand what DRBD is > DRBD is a block device which is designed to build high availability clusters. This is done by mirroring a whole block device via (a dedicated) network. You could see it as a network raid-1.

    A short discription of how this will work when the 1.70 version is released. This is all the information that I will provide, as a later date will have more info on the subject.

    Target Volume Replication:

    iSCSI Target Volume Replication replication is very similar to RAID 1. The
    first stage is rebuilding of the destination to be the copy of the source
    volume. Next stage (endless) is online modifying the destination volume to
    keep the mirror. The difference comparing to the RAID 1 is that, after any
    broken connection only the changed data will be 'rebuild' (again first stage
    takes place) on the destination.

    Note: the replication should be performed on separate NIC and the
    connection should be as fast as the main network connection, to prevent
    lowering data throughput. Once you create the Target Volume you have the
    choice to set it as
    Source or Destination to the mirrored server. Replication of volumes should
    be same size.

    Changing destination to source without loosing data is only possible when
    data is consistent.

    How to change source to destination:
    1. Stop replication task on source or turn off server
    2. Now it will be possible to change destination to source, when the data is
    All the best,

    Default HP servers

    I hope that you allready instaled open-e on HP 380.
    But, if you are still considering this opportunity I want to issue one warning.
    Some time ago I played with HP servers:
    ML 110 G2, ML150 G2 and ML350G4p.
    There I was surprised:
    ML 110 G2 worked ok.
    ML 150 G2 worked with random crashes - I think this can be fixed.
    ML 350 G4p It was impossible to install open-e iscsi target on this machine.
    It has BIOS which reports any IDE cntroller as SECONDARY.
    HP support refused t fix that. According my knowledge this is not fixed even today.
    I just want to warn you about such situation.

    This is very good information and I want to thank you for your time on this. This helps others and us. It is very expensive to test every system manufactured, unless we started to charge very high prices for our products.

    From all of the Open-E engineers we thank you!!
    All the best,
