Experience with Fibre-to-Fibre RAID controller?

    Hello All,

    As mentioned before in this ng, I'm new and a little busy composing a small
    san environment. Currently I'm looking on eBay to find some hardware but
    can't find (or pay) an all-in-one solution that fits my needs.

    I would like to use a disk array with onboard raid controller (raid 50) and
    a fibre channel interface. Now I've found two separate devices: Dell
    Powervault DAE 630F with fibre-channel and Eonraid 2000r2 SAN fibre-channel
    raid controller.

    The Powervault does not have any raid controller onboard, the Eonraid is an
    external box equipped with six fibre-channel interfaces. Now I'm curious if
    this could be shaped in a working san. Of course I've read the data-sheets
    and therefore I'm almost sure this should work like a normal san (not that
    I'm a san expert). But I just want to check it with you guys, it does
    concern a lot of money for a single person and I don't want to buy expensive
    stuff that is useless to me.

    EonRaid 2000R2: http://www.infortrend.com/legacy_er2000.asp

    So, someone have any experience or opinions about this matter?

    Sincerely,
    Marcel

    It depends what you define as a SAN (or what you need a SAN for...).
    Usually this includes at least one Fibre Channel switch, since the SAN is used
    to allow a bunch of hosts to do IO to a bunch of storage over a fabric.

    Now with this Eonraid, it seems that you have 4 or 6 FC ports you can connect to
    either storage or hosts, and then you configure it to map luns on one or more
    WWNs to Raided disk volumes.

    It seems to me it lacks one of the key features of a SAN, which is
    extensibility. A configuration with a proper RAID box and a switch can grow both
    in number of hosts and number of raid boxes. Your config will be limited both in
    the number of hosts and the number of disks.

    I didn't expect to grow as it is for a small (home) network.. I'll just wait
    untill I've received a tutorial book that I've ordered last week. That
    should improve my knowledge of san before I start buying hardware. Although
    I did see some nice hardware with fair prices.
