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.

does the cage work with any intel 2u server or does it have any specific one?

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.
