I have a 12 drive backplane which can host both SATA and SAS drives.
8 of the slots are occupied with 4TB spinning Hitachi drives. Those drives blink the activity LED's when being accessed.
2 of the slot are occupied with 512GB Intel SSD5 (SSDSC2KW512G8X1) drives. No matter how hard you utilize those two SSD drives no LED activity shows.
The backplane is connected to a 16 port 12Gbps Adaptec/Microsemi controller.
The PC manufacturer (SuperMicro) has suggested it is the SSD drive that is not sending the correct activity pulses to the backplane.
Is this something that can be addressed via software/settings for the drive itself?
Thanks for posting in our community.
The Intel® SSD 545s Series has no LED of its own. In this case, lights are reported by the adapter/controller. Not all drives use the same pin configuration, it is possible the adapter is not using the right ones for these SATA SSDs.
We recommend updating the firmware/BIOS on system, controller and https://www.intel.com/content/www/us/en/support/articles/000017245/memory-and-storage.html drives.
Please let us know if there's anything else we can do for you.
