Hello Novanet   No, the only validated controller that supports JBOD/Non-RAID mode is the H200. You can configure all of the HDDs as single drive RAID 0's, but I'm not sure if that will work with the ceph cluster.   They are 3Gb/s ports with a max theoretical speed of 300MB/s.   Yes, you can install two per channel for a maximum of 144GB.[URL] 16GB DIMM, 1333MHz, 2RX4, 8X, 240, Regulatory, Low Voltage Thanks
Hello, Trying to build Ceph cluster with 12x3.5 HDDs in non-raid config and 2x SSD is connected to on-board sata ports used as journal device.  I have two questions regarding my current c2100 servers.  1. Does LSI SAS 9211-8i works with C2100 3.5 backplane expander in non-raid mode? If yes, where is the jumper settings diagram. I can't find it in the hardware manual. 2. What's the speed of on-board sata ports? is it sata 3? Hardware manual does not have the sata port details.  Thanks, Novanet
