Abstract
A method for performing cache flushing operations in a data storage system can include maintaining a plurality of SSDs as a cache medium for a data storage medium, controlling a region of the SSDs in a write-back cache mode, and monitoring a status of the SSDs to detect a low-performance condition. In the write-back cache mode, data is mirrored across the SSDs. The method can also include performing normal purge operations on the data stored in the region under a condition that the low-performance condition is not detected, and performing aggressive purge operations on the data stored in the region in response to detecting the low-performance condition. The normal purge operations can include flushing the data stored in the region to the data storage medium. The aggressive purge operations can include sequentially mirroring the data stored in the region to one or more special territories of the data storage medium.
