P3500: no support for NVMe sleep modes

[anomaly]

I have found out that P3500 drives don't seem to support sleep modes.... after suspending the kernel cries out about how the drive will refuse to reset. Tested with 6.x and 5.x (Linux, obviously).

Anyone else has any suggestions or knows of any way to fix it?

If you want effective sleep with SSD, need to switch to SATA with good ALPM implementation imho. That will save power. See Aggressive Link Power Management - Wikipedia

I have such a SATA SSD in my cheap Acer Swift 1 13" notebook and it sleeps really really well - because not NVMe.

NVMe sleep works fine with consumer or prosumer drives, at least in my experience. But the Intel P series don't tolerate sleep modes. The controller fails to come back after S3.

I checked and no new firmware is available... Guess I will add another drive to one of the cluster hosts ;P

Working just fine on my Intel P4600 and P4610. Over 1500 power cycles on the former from putting my workstation to sleep every night. Running Windows 10 though, so might be Linux specific?

I haven't installed Win11 on that particular system yet. I do have some P4xxx series to test, do you recommend them vs the P35xx series? ex. for a workstation role. I could relegate the P35xx to the server (it doesn't need the most recent or best, I just need the IOPS and latency).

Thank you for checking in!

I'm only running them because I got them for a good price, not the need for high endurance or write performance (averaged less than 1TB a month in writes). Honestly you should be fine with either for most workloads.

That's good to know! I yanked my p4610 3.2tb out because the heat\power didn't justify the cost savings, especially nowadays... but having it sleep worth a test!

I will go check which models I have, tomorrow probably. @T_Minus let us know if it worked.

I can confirm Linux 6.2.x won't support sleep modes for my 3520:
