Abstract

This disclosure proposes a "volatile write-back mode" implementation. In this instance, the RAID configuration maintains its original write-back/write-through configuration setting. In a separate part of the configuration is the volatile write-back mode setting which consists of a counter. At boot time, if this counter is non-zero, write-back mode is forced on the controller during that boot period. When the system is rebooted, the counter (if non-zero) is decremented. The counter is initially set by a command from the host.
