Abstract
The controller performs in-line compression of plaintext data from a host and post-process compression of in-line compressed data stored in one or more storage drives. In the in-line compression, in-line compressed data is generated by executing a compression process including first dictionary compression on the plaintext data from the host, and the in-line compressed data is stored in the one or more storage drives. In the post-process compression, the plaintext data is generated by decompressing the in-line compressed data read from the one or more storage drives. In the post-process compression, post-process compressed data is generated by executing a compression process including second dictionary compression on the plaintext data using the processor, the second dictionary compression being more excellent in character string search capability than the first dictionary compression, and the post-process compressed data is stored in the one or more storage drives.
