I also have fans stuck at 100%. Where might I find this setting option? I also feel a bit an idiot...

Mine also arrived with virtualization disabled, be sure to go through all the bios options and fix: https://www.cisco.com/c/en/us/td/do..._41_appendix_010001.html#reference_mfv_f31_5z
Another drop of what looks like the same spec - Cisco UCS C240 M5 Server TWO Xeon Gold 6132 CPU 128GB DDR4 RAM CIMC Clear-NO HDD
I bought one of these UCS240M5SX's back in November and am just now getting around to setting it up. It was smooth sailing until I tried to add two brand-new Intel Optane 905p U.2 drives to the chassis. It doesn't seem to recognize them.
The system log states code F0776: "REAR_HDD1_PRSNT: An invalid drive population detected on Rear HDD slot 1 : Please replace the drive or check system configuration."
They don't show up in inventory or under Storage > Cisco 12G Modular SAS HBA > Physical Drives
I'm pretty sure front slots 1-2 as well as both rear slots are supposed to support NVMEs? Does anyone here have experience running U.2 drives in one of these? All the system firmware, etc. was updated to the latest release.
Thanks for any pointers!

Looks like it. Though I don't know if the cable itself is 100% identical. I don't see any explicit "PCI-E" label anywhere like in your picture.
If I insert the drives in front slots 1 or 2 (these are also supposed to support NVME), they don't show up either, although the bay lights up green and I don't see the "An invalid drive population" warning in the system log.
You have a SAS version of the backplane, PCIe connector is twice wider and connects directly to the nearest riser instead of the SAS controller
Ahh, that makes sense. For some reason I thought the SAS controller was able to handle NVME as well. Thank you very much for the insight!
After more research, it seems like I'd need a cable (UCSC-RNVME-240M5) and a different Riser 2 (UCSC-PCI-2B-240M5 or option 2C) to connect it to.
Will try to acquire those and run the Optanes on PCIE adapters directly connected to one of the existing risers for now.

Can you elaborate on this? I have two C220 M5Ls and one just randomly ramps to 13k rpm regardless of fan profile
That is what I mentioned here. The logic behind the fan control is unknown. Fans can sit still at 3.5k until the CPU temps reach 99°C than slowly increase RPM to 8k. But it also can ramp fans RPM instantly to 13k the moment when short spiky load is removed from the CPU. I didn't get the algo behind it and each new firmware revision doesn't fix it. Tried with various CPU's TPD and DIMMs amount to no avail.
But this behavior is not impacted by 'unknown' PCIe cards - I have WX 4100 GPU and Fusion IO PX600 installed. Even Samsung U.2 NVME marked as 'moderate fault' because of unknown firmware doesn't change the idle fan behavior. Servers of other vendors usually shift fans RPM to max after detecting anything 'foreign' in PCIe slots
What makes very little sense is mine is sitting idle, you can watch the CPU temp in the console slowly creep to 45. It then ramps to 13k and takes several minutes to ramp back down. The other server with a Gold 6132 doesn't do this.
This only PCI devices in this server is a Cisco X710-DA2.
Did either of you try this? I have a C240 on the way, and it has the SAS backplane.
Will buying UCSC-RNVME-240M5 & UCSC-PCI-2B-240M5 be enough to convert it to NVMe?
I’ve bought and installed the parts and it all looks good, but I don’t have a spare U.2 around at the moment to actually test this. The ones I planned on using are already in use in another server.
Ultimately the 240 was sadly too loud for my homelab situation. It’ll probably go to Colo soon. If I manage to find a U.2 for testing, I’ll post here.
FYI I got exactly the parts you mentioned and the swap was very straightforward.
