Methods and an apparatus for RAID load balancing are provided. One exemplary
method includes establishing first and second counters where the first counter
is associated with a first drive and the second counter is associated with a second
drive. Next, a command is received form an operating system. Then, it is determined
if the received command is a read command. If the received command is a read command,
then the counters are examined to determine which of the counters is a lower value
counter or if the counters are of equal value. Next, a drive associated with the
lower value counter is selected or if the counters are of equal value a first drive
is selected. The lower value counter is then incremented. Then, the read command
is directed to the drive associated with the lower value counter or the first drive
if the counters are of equal value.
