I am building a NVMe SSD NAS for XCP-ng (open source alternative of Citrix Xen), it will be connected to each host directly via fiber (no switch), I already use a similar setup but with SATA SSD. I have been reading about NVMe support and mixed reviews and responses. I am listing the spec of my buildout and would like to see if anyone have some advice to optimize this build.
  1. SuperServer 2028U-TN24R4T+
  2. SuperMicro X10DRU-i+
  3. 2 x Intel Xeon E5-2620 v3
  4. 384GB (24 x 16GB) 2RX4 PC4-2133P DDR4 MEMORY
  5. 24 x Intel DC P3600 SSD 800GB NVMe PCIe 3.0
This will be connected via fiber to each XCP-ng hosts serving as iSCSI target which will have all the VM's. I am wondering if out of the box install will be good enough or should consider adding ZFS ZIL and SLOG, and any other considerations...

@markmuehlbauer it went almost well, except only 16 drives are usable and rest start to throw errors, I was hoping with the new 11.3, that would be fixed but it did not.

How many PCIe lanes do your processor and MB support? (NVME devices need 2 or 4 lanes each).
