Troubleshooting Oracle 6.4 TB NVMe SSD v2 Cooling

Maintaining the proper internal operating temperature of the server is crucial to the health of the server. To prevent server shutdown and damage to components, address overtemperature and hardware-related issues as soon as they occur.

Use the status indicator LEDs to determine the status of the Oracle 6.4 TB NVMe SSD v2. The LEDs provide key status information to diagnose SSD issues. See Status Indicators.

The Oracle 6.4 TB NVMe SSD v2 is designed to provide continuous full bandwidth performance with temperatures up to 73°C. Qualified host platforms with required software updates operate with sufficient margin to the maximum temperature under worst case environments. Should the system maximum operating temperature be exceeded or a system fault occur that causes internal temperatures of the flash memory modules to rise above this limit, the SSD responds as follows:

  • 73°C – Drive write throttling is engaged to reduce SSD power.

    • SSD amber status indicator LED is lit, Service Action Required.

    • Temperature warning is displayed in utility output.

  • 78°C – Additional drive write throttling is engaged.

    • SSD amber status indicator LED is lit, Service Action Required.

    • Critical temperature status is displayed in utility output.


      Caution

      Caution  -  Sustained critical temperatures might cause data loss.


Refer to the server documentation for additional service information.
