Environmental Specifications

Language:

The Sun Flash Accelerator F80 PCIe Card operates and is stored in an environment defined by the following parameters:

Specification	Measurement
Temperature range	Operatiing temperature: 0 ˚C to 74˚C (measured at card temperature sensor) Operational environment: 5 ˚C to 55˚C (dry bulb) Storage and transit environment: –20 ˚C to 75 ˚C (dry bulb) Thermal sensor temperature cannot exceed 75 ˚C Maximum dry bulb temperature shall be derated by 3.3 ˚C per 1000 m above 500 m Four thermal sensors on the cards monitor each flash memory module
Relative humidity range	Operational environment: 8% to 80% noncondensing Storage and transit environment: 5% to 95% noncondensing Non-operating: -20˚C to 75˚C noncondensing
Altitude	Operational environment: Up to 9840 ft (3,000 m) Storage and transit environment: Up to 39,370 ft (12,000 m)
Airflow requirement	More than 200 LFPM (linear feet/minute)

The Sun Flash Accelerator F80 PCIe Card is designed to provide continuous full bandwidth performance with flash memory module 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 which causes internal temperatures of the flash memory modules to rise above this limit, the card responds as follows:

74 ˚C - Drive write throttling is engaged to reduce card power.
- Card status LED yellow.
- Temperature warning displays in ddcli -health output.
76 ˚C - Additional drive write throttling is engaged.
- Card status LED red.
- Critical temperature status displays in ddcli -health output.
  Caution - Sustained critical temperatures may cause data loss.
