Troubleshooting Oracle F320 Flash Card 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 F320 Flash Card 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 F320 Flash Card responds as follows:
-
55° C - Operating temperature ambient.
-
0 to 55° C at 300 LFM minimum airflow
-
Ta is ambient temperature measured above the hottest point on the heatsink with the airflow condition of more than 2.5 CFM at 25° C of ambient temperature.
-
-
70° C - Operating temperature limit.
-
The card independently operates and provides continuous full bandwidth performance with temperatures up to 70° C.
-
-
78° C - Drive write throttling is engaged to reduce Oracle F320 Flash Card power.
-
SSD amber status indicator is lit, Service Action Required. See Status Indicators

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 Oracle Flash Accelerator F320 PCIe Card Operation in Oracle Flash Accelerator F320 PCIe Card and Oracle 3.2 TB NVMe SSD Product Notes.

-
85° 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.
