Drive Configuration and Status
CS-Storm 500NX 1U server NVMe slots and LED definitions.
The CS-Storm 500NX 1U server supports sixteen 2.5-in disk drives. Eight hybrid connectors on the drive backplane (slots 8-15) support NVMe or SAS/SATA drives , and slots 0-7 support SAS or SATA drives.
The NVMe ports provide high-speed low-latency connections directly from the CPU to NVMe solid-state drives (SSDs).

Drive Carrier LEDs
Each SAS/SATA/NVMe drive is mounted in a drive carrier with two status LEDs on the front of the carrier. The drives are mounted in these drive carriers to simplify their installation and removal from the chassis. These carriers also help promote proper airflow through the drive bays.

Blue | Blinking/flashing | I/O activity | |
Off | Off | Idle SATA drive | |
Status/Failure LED | Red | Solid on | Failure of drive with RSTe support |
Red | Blinking slow ( 1 Hz) | Rebuild drive with RSTe support | |
Red | Blinking with two blinks and one stop at 1 Hz | Hot spare for drive with RSTe support | |
Red | On for five seconds, then off | Power on for drive with RSTe support | |
Red | Blinking fast ( 4 Hz) | Identify drive with RSTe support | |
Green | Solid on | Safe to remove NVMe drive | |
Amber | Blinking at 1 Hz | Attention state - do not remove NVMe drive |
