    Hi Mohamed,

      thank you for your reply.

      I thougt, there is a SAS-Expander on the backplanes of the SC847,
      so all drives can be run. Am i wrong?

      
      thanks,

        Hi Markus,
        

        X10DRH-CT can support
          only 16 drive as default. If you want to connect more
          drive,there is a special SKU for more drive support from super
          micro or you need additional SAS controller. We are using 2630
          V3( 8 core - 2.4GHz) *2 for 30 drives on SM X10DRI-T. It is
          working perfectly on replication based cluster. If you are
          planning to use erasure coding, you have to think about higher
          spec.
        

          Does any one
              know about the exact processor requirement of 30 drives
              node for erasure coding? . I can't find suitable hardware
              recommendation for erasure coding.
          

          Cheers

          Hi,

            i have a backup-storage with ceph 0,93

            As every backup-system it is only been written and hopefully
            never read.

            
            The hardware is 3 Supermicro SC847-cases with 30 SATA-HDDS
            each (2- and 4-TB-WD-disks) = 250TB

            I have realized, that the motherboards and CPUs are totally
            undersized, so i want to install new boards.

            I'm thinking of the following:

            3 Supermicro X10DRH-CT or X10DRC-T4+ with 128GB memory each.

            What do you think about these boards? Will they fit into the
            SC847?

            They have SAS and 10G-Base-T onboard, so no extra controller
            seems to be necessary.

            What Xeon-v3 should i take, how many cores?

            Does anyone know if M.2-SSDs are supported in their
            pci-e-slots?

            
            Thank you very much,

              Markus
