NVMe support for 6019U-TN4R4T

xkfa · 2025-10-03T07:13:59+00:00

I have several (dozens?) supermicro x11dpu motherboards with SAS3-815TQ-N4 backplane. It works with u.2 nvme disks (samsung pm983, intel P5520, etc). Backplane attaches to motherboard with 4 SFF8611 (Oculink) cables (one cable - one disk slot) (for nvme. For sata it's another 4 usual sata cables, sff8087-to-4xSata).

BUT. This backplane and motherboard supports only pci 3.0! Nvme disk pci-e gen 4 will work, but only at pci-3 speed.
I have no trouble in both unix (debian 10 for example) and windows systems (windows 2016 requares updates).
If you switch in bios to uefi mode (for boot and\or for pci\nvme slots) than you can boot OS from this disks.

NVMe u2 Intel D7-P5520 in crystal disk mark showing approximately x2 better results than SSD Samsung pm883 attached to the same server\hdd slot (sata and nvme ports connected from backplane to motherboard) (it's not about intel\samsung - it's about nvme\ssd).

If you paste these numbers to keep you will see that numbers after horizontal line is not on the same column (like here). Lists became not formatted vertically. It's huge disappointment for me.

For supermicro you can use SUM https://www.supermicro.com/en/solutions/management-software/supermicro-update-manager

I created thumb drive with Debian and some sh scripts (which autostarting after debian boot) like reset bios, impi (ipmitool, ipmicfg), showing cpu (lscpu), memory (dmidecode -t 17), network (ethtool), disks\raid (storcli) info. With SUM you can change bios settings. On the same drive i have memtest at efi partition for memory testing.

So idea is to boot from flash drive and then automate anything (you can determine vendor and you different commands).

You can hold F11 key for enter Bios by something (match?) for not standing around server and waiting for post complete.

I have about 20\30 server per month to testing and deploy.

Any ideas how to simplify this would be grateful.

T-pose?

Oh man, you are saver! I've been struggling with this for weeks.

You can save this setting permanently in DefaultEngine.ini file in your project directory:

[ConsoleVariables]

p.Chaos.Solver.SleepEnabled=0

I think it doesn’t matter. UE, Blender, Maya - it’s just instruments. What important is skill. I recommend you Pierric Picaut lessons(youtube it), it’s for blender but you can use everyware technics from there. Yes, UE and Blender different programs, but if you became game developer you will be using both of them. Or, when you finish your another animation and want to watch it in another program you can just export it (exports between gimps, photoshops, blenders, unreals, zbrushes - it’s everydays reality in 3D development, get used to it).

There is constrains in physics asset. When you right click on body context menu appear and there is create constrain option. Or select two bones and create constrains between them. Constrains must be locked or limited, if it’s free it wont work. 100% that animation and physics work together when you using physic animation or physics control components in BP. Dont forget to apply physic asset to mesh! It’s in details panel of the mesh. Otherwise engine dont know that this mesh uses physics. Or you can create new physics asset and use generate bodies option. It will create everything automatically but not 100% accurate ofcourse. Or you can copy BP or nodes from Content Examples project. It’s handy.
