5/12    My work is planning on ordering a raid box and we're considering
        going with fibre channel instead of scsi.  none of us have worked
        with fibre channel.  can anyone recommed for/against any brand of
        fibre channel?  the raid manufacturer is quoting us with a qlogic
        board.  we'll be running it on linux, but experience with any os
        is appreciated.
        \_ You will be able to get *lots* of bandwidth over the fibre
           channel solution, assuming you are going with 7+ drives.  The
           CSUA has a fibre channel raid array that hosts the office
           accounts and the debian mirror, plus some.  It is running
           software raid 5.  We only have a 1Gbit backplane, which I
           can easily saturate when doing linear disk access.  Qlogic is
           the defacto fibre channel controller card.  Make sure you have
           at least a QLA2200 card.  I wasted 6 months of lockups when
           doing testing with a QLA2000 card.  No driver issues
           since the change-over.  If you have any questions, let me know.
           -- njh
           \- helo how much $ did you spend for how much storage?
              i have some SATA numbers built fairly cheeply but an
              curious about the perf gain if we spend a little more $
              ok tnx. --psb
              \_ About $2000 for 1/2TB of 10K RPM 36GB drives in 2 chassis
                 with redundant power supplies.  This was for surplus,
                 unused netapp hardware w/1 year warranty, and 2 spare disks.
                 And no, I can't get such a good deal anymore.
        \_ Or you could get an external hardware raid box like the Arena from
           Maxtronic.  The low end boxes are IDE drives attached via FC or
           SCSI (your choice).  Rock solid.  Cheap enough with decent perf.
        \_ you didn't mention what os you're planning on using it with.  I
           can tell you now to avoid JNI cards like the plague.  We're still
           having issues (linux)

5/6     http://goo.gl/KiIMT (shortened link from http://HP.com)
        seems like I get these every 6 months or so from HP.  Do all drives
         have these kind of issues and I only see the ones from HP because
         they are diligent about reporting/fixing these issues?  Or do they
         suck?   (It's not actually their drives so...)  Also, do I really
         need to bring down my production infrastructure and fix all this

1/4     I want to test how my servers behave during a disk failure and
        a RAID reconstruction so I want to simulate a hardware failure.
        How can I do this in Linux without having to physically pull
        a drive? These disks are behind a RAID card and run Linux. -ausman
        \_ According to the Linux RAID wiki, you might be able to use mdadm
           to do this with something like the following:

9/13    Thanks to Jordan, our disk server is no longer virtualized. Our long
        nightmare of poor IO performance should hopefully be over. Prepare for
        another long nightmare of poor hardware reliability!

2/14    You sure soda isn't running windows in disguise?  It would explain the
        uptimes.
        \_ hardly, My winbox stays up longer.
        \_ Nobody cares about uptime anymore brother, that's what web2.0 has
           taught us.  Everything is "stateless".
           \_ You;d think gamers would care more about uptime.

7/22    Playing with dd if=/dev/random of=/dev/<disk> on linux and bsd:
        2 questions, on linux when <disk>==hda it always gives me this off
        by one report i.e. Records out == records in-1 and says there is an
        error. Has anyone else seen this?  Second, when trying to repeat this
        on bsd, <disk>==rwd0 now, to my surprise, using the install disk and

1/26    What's a good motherboard I can get that will fit in a 1U
        case, with sata connectors, gig-e ethernet, and lots of
        slots for RAM?  I also don't want to have to use expensive
        double buffered RAM.  Can you tell I havne't bought a PC in
        years?  thanks.
