scared shitless by posts about RAID controllers and OES2 / 11

Can anyone recommend a decent RAID controller for SAS

(1) That runs out of the box
(2) That does NOT stop working on Kernal updates
[ at least in your experience upto now... who knows in the future]
[ I probably won't do updates once installed in production life
for fear of breaking it ... unless a mega security fix is required ]
(3) I only need RAID 1 support

Server will support 20-25 users fairly active users with CAD files

I have LSI megaraid 8208ELP and Teckram Fastrak 4650 - neither of these seem
to work
I've downloaded latest drivers and installed

Someone suggeted Adaptec 6504 or HP Smart Array 462828-B21 - both work on
REDHAT not tried on SLES

    Brian, you need one which is supported in the linux kernel itself not
    with a separate driver as you have surmised. I was in the same position
    myself a couple or years ago.
    Unfortunately it is unlikely to get that cheaply because those are not
    real RAID cards the low end card I used is the HP Smart Array E200i
    (includes BBWC) although whether that is still available seems debatable.

    Although the P212 you refer to seems the basic unit from HP now.

    The thing about the proper HP Smart Array controllers, (not counting the
    B110i) is the drivers "cciss"
  • Thanks for your detailed response.

    Not getting anywhere fast I did order a P212 today

    I did have HP E200 - but couldn't find the cables ! - so went for a P212...
    here's hoping !

    I'll take a look a the links you gave.

    Thanks again.

    Then you need a RAID card that is a full hardware RAID card and not one of the fairly recent class of WinRAID
    cards that are really only for Windows 'servers' and only for the matching version of Windows (don't expect to
    be able to use those for next generation of Windows). This whole inexpensive class is like the WinModems of
    the 1990s that only worked for specific ranges of Windows and nothing else.
    Most if not all of the respectable RAID controllers have them, so you can't just go by brand name, but have to
    look closely to see if the hardware vendors explicitly support SuSE/SLES for the particular model you are
    looking at. I even do that for Windows server installs just so that I don't have to worry about it when it
    comes time to upgrade the server down the road.
    The old saying "you get what you paid for" does apply here. If you go cheap........

  • As an addendum, Dell's Linux support pages seem quite comprehensive with
    some interesting information about LSI which is their primary manufacturer.

    However to me it is not quite clear enough so I would only risk my job
    on it with some thorough testing.
