Troubleshooting NVMe Drive Cooling
Maintaining the proper internal operating temperature of the server is crucial to a the health of the server. To prevent server shutdown and damage to components, address over temperature and hardware-related issues as soon as they occur. Refer to the server documentation for additional service information.
The Oracle 3.2 TB NVMe SSD is designed to provide continuous full bandwidth performance with temperatures up to 70° C. Qualified host platforms with required software updates operate with sufficient margin to the maximum temperature under worst case environments.
 | Caution - Sustained critical temperatures might cause data loss. |
Should the system maximum operating temperature be exceeded or a system fault occur which causes internal temperatures of the flash memory modules to rise above this limit, the Oracle 3.2 TB NVMe SSD responds as follows:
-
70° C - Operating temperature limit.
-
The SSD independently operates and provides continuous full bandwidth performance with temperatures up to 70° C.
-
70° C is the Case maximum (based on hottest point on case surface). Tc is measured at the hottest point on the case with the airflow condition of more than 2.5 CFM at 25° C of ambient temperature.
-
-
76° C - Drive write throttling is engaged to reduce SSD power.
-
SSD amber status indicator is lit, Service Action Required.
-
First threshold for Dynamic Thermal Throttling (DTT). Critical temperature status displays in utility output: Critical warning 1 ‐ Temperature exceeded critical threshold.
Use the Oracle Hardware Management Pack CLI commands to determine the temperature and status of the Oracle 3.2 TB NVMe SSD. See Verify Oracle 3.2 TB NVMe SSD Operation in Oracle Flash Accelerator F320 PCIe Card and Oracle 3.2 TB NVMe SSD Product Notes.

-
83° C SSD I/O stop overtemp critical limit.
-
SSD component shuts down.
-
Critical temperature status displays in utility output: Critical warning 1 ‐ Temperature exceeded critical threshold.
