Parts
- X10DSC+ Motherboard
- AOM-S3108M-H8L RAID/HBA
- AOC-MTG-I4S quad SFP+ NIC
- 8x32 GB RAM (256g)
- 24x Seagate ST16000NM002G Exos X16 16TB 12Gb/s SAS
- 375 GB Optane SSD for l2arc/ZIL SSDPEL1K375GA01
- 3 4tb m2 SSD for Special Devices
Disk Layout
ZFS zraid2
Zpool 3 - 6 disk raidz2 1 - 5 disk raidz2 Special - 3 m2 flash Zil - 16 GiB - optane l2arc - 333 GiB - optane Note optane is shared between Zil and l2arc
Space on this should be 15 disks of 16 tb, with redundancy or 240tb. This will leave one disk open as a hot spare.
The sata disks will be linux boot disks in a standard linux raid (maybe zfs mirror?)
SAS controller
The built in controller supports HBA mode per supermicro.

Doesn't work in JBOD mode, everything is proxied.
Updating Disks
Firmware
Current firmware on the disks is E004, but disks have E002 on them

Low Level Format
It's necessary to low level format these disks as we need to turn off Protection Type 2, test the sectors of the drive and make it a 4096 sector size.
# SeaChest_Format --protectionType 0 --formatUnit 4096 --confirm this-will-erase-data --poll -d /dev/sg2
NVME Config
This was the most dificult. The onboard NVME ports under the power supply will take a standard NVME cable, but do not supply any power. The M.2 to SFF-8612 adapters don't have a power connector, so I was able to add some 3.3v inputs on the filter cap. This was kinda hacky, but it works.
Optane
The optane SSD needs to be changed to 4k sectors, but the nvme command doesn't work. Intel has a intelmas program that does https://community.intel.com/t5/Intel-Optane-Solid-State-Drives/4K-format-on-Optane-SSD-P1600X/m-p/1477181

Phsyical layout
Mandatory config
The disks don't deal with the old NVME support on this box (it's listed as oculink .91, not 1.0) and there are some bugs in linux around this and power handling.
A config must be added to the kernel cmdline
vim /etc/kernel/cmdline
add this to it:
nvme_core.default_ps_max_latency_us=0 pcie_aspm=off
then
proxmox-boot-tool refresh
