    Hello,

    We have been running Open-E v6 FULL on our PowerEdge 2950 for a few years now, and it works just fine. I seem to remember that there is a single spare SATA socket on the motherboard, so...

    Thanks!

    OK, I shall give it a go!

    I am in talks with the SAN vendor (Open-E) to get them to enable read-only mounting of LUNS for this purpose.

    Thanks again,

  3. Different subnets

    Hi there,

    If I were you, I would seriously consider moving each MPIO path to a different subnet, since VMARE and OPEN-E will not know which adapter to send the traffic out on, since they all share...

    One other thing

    I don't believe you should enable write back cache if you are intending to use iSCSI failover, as the pop-up dialog suggests.

    Cautious

    Thanks for your reply.

    While I appreciate this is possible I am VERY concerned that the Windows XP box we have running Veeam might, in an extreme case, write to the VMFS ISCSI LUN in some way...

    Invest in a UPS

    Hi there,

    As the message suggests when you go to enable Write Back mode, I would suggest you invest in a decent UPS to power your SAN. This will ensure Open-E has time to gracefully flush its...

    If you place a single gigabit card in both the primary and secondary, then with a fast enough disk array at each end, you will easily saturate the gigabit ethernet connection.

    Curious

    Hi there,

    Perhaps I have mis-read your question, but I don't believe Open-E yet supports software RAID10? Unless this has changed in the latest release?

    Do you actually mean that your primary...

    things to watch out for

    If you have any form of write cache enabled, then beware that what you may measure is the rate at which you can write to DSS's cache rather than to the disks. Once that cache fills up, you then start...

    Controller?

    HI there,

    What controller are you using? Is it a hardware RAID controller? How are the disks configured if it is a RAID array?

    Cheers

    Vlan?

    I'n my simple mind, it would stand to reason that the DSS must have the same number of connections (network cards) as the servers have I.e. four cards in the DSS with IP's 10.0.1.10 10.0.2.10...

    Resolution?

    Hi there,

    Did you ever resolve this problem?

    Is this not an issue if you boot off a USB-DOM instead of the PERC?

    Dell PERC5 or 6 support
