    Need to upgrade from Dell MD1200 JBOD. What's the best out there?

    in Storage Devices and Controllers

    Posted

    I currently have a 4U chassis holding an AMD motherboard and accessories.  From there, I have 2 SFP cables going to a DELL MD1200 rack unit.  It's been flawless for several years but now the fans are at full speed and I can't stand the noise.  I don't care to troubleshoot what's wrong either.  Who makes the BEST JBOD rack case for atleast 12 drives?  My current setup is a 6GB throughput system.  Does UNRAID support faster controllers now?  

    Unraid 6.9 crashes every few days and now docker service does not start.

    Probably because you filled it. Why have you given 55G to docker.img? Have you had problems filling it? 20G is usually much more than enough and making it larger won't fix anything, it will only make it take longer to fill.

     

    The usual reason for filling docker.img is an application writing to a path that isn't mapped.

    How do I find out which application it is?

    I think that you should focus on hardware. Unraid is a very stable operating system. If you are crashing every few days then there is (more than likely) something wrong with your hardware. I'd start with memtest86+ for a few days. This is never an easy problem to solve. If that passes, then try running with very few HDD (or, if possible, no HDD) for a few days and see if you are stable. There's usually something.

    See attached diagnostics.

    This particular setup was running on a Dell rack server.  It gave me the same issues there.  I decided to use a AMD Ryzen based system with ASUS board.  No luck 

    Changing Cases and question on SAS cables

    in Hardware

    Posted

    I currently have a CHENBRO rack case with 12 drive slots.  The system has a supermicro dual CPU board with LSI controller.  I believe there is a single SAS cable going to the rear of the drive backplane to connect all 12 drives.  

     

    Question 1.  I thought a single SAS connector can hookup to only 4 drives.  In my case, I can operate all 12 drives (atleast 8 so far installed)

     

    I would like to switch to a dell r430 that I happen to have with a 20 core processor.  Since the dell is a 1u unit, I would like an external drive storage unit.  

     

    Question 2.  Which is the quietest and highest quality hotswappable drive cabinet?  

     

    The dell also have a mini perc controller that has been flashed with IT firmware to see the 8 2.5" drive slots on the case itself so that is not a problem.  


    Question 3. Can I add another LSI controller with external port to manage the external drive storage unit?
