Understanding the Operating Temperature Range for the ioDrive

The ioDrive is designed to operate in an system where the temperature ranges from 0 degrees C to 55 degrees C, with at least 300 LFM airflow*.  This ambient or environmental temperature range is provided in the ioDrive data sheets.  The end user can compare the ambient temperature reading as reported by fio-status with what is listed in the data sheets.  (The 1.2.6 fio-status utility reports "board temperature" in place of  "ambient temperature".)

The product data sheets are available at:
