Abstract
The present invention relates to executing data compression based on the used capacities of real pools. The present storage subsystem stores a definition information regarding conditions of starting data compression and ending data compression defined via usage rates of a real pool as physical area, wherein if the usage rate of the real pool satisfies the condition for starting compression, the compression processing is started, and if the usage rate satisfies the condition for ending compression, the compression processing is ended.
