    Might be a fun thread. I went to the DC today with the full package as I posted here.

    Newly installed:
    Intel A2U44X25NVMEDK (including 2x PCIe cables, 1x SAS cable, hot swap cage, new PCIe riser, add-in card for the 4x drive support.)
    4x Samsung SM1625 200GB SAS
    1x Intel P3700 400GB AIC
    1x Intel P3600 400GB AIC
    2x Samsung XS1715 800GB
    1x Intel P3700 800GB SFF
    1x Intel P3600 400GB SFF
    8x 16GB DDR4 RDIMMs= 128GB RAM for a total of 256GB

    Removed:
    2x Fusion-io ioDrive 353GB MLC

    I rebooted the server, saw NVMe scroll past, unhooked the KVM cart and went home. When I got home I decided to try running a few benchmarks and I only saw two NVMe devices that looked like:
    Code:
    Disk /dev/nvme1n1: 372.6 GiB, 400088457216 bytes, 781422768 sectors
    Units: sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    
    There should have been 4. I did take a few pics of the installation to share when I saw this:
    Intel NVMe SAS hot swap backplane installed-small.jpg

    See if you can find what is wrong and share your #epicfail server build.

    Either that or the SAS Mini-HD port is unplugged. But I bet it's the power as I have done that a few times myself. :D

    I think it will fit the 2U E5 chassis with the blank spot in the middle. Apparently, it can only be installed in that middle position for thermal reasons.

    Those are just "extra" drives. I kept 2 drives of each type I could in the lab for testing.
