  • Storage apparatus
    Patent number: 8438403
    Abstract: Provided is a storage apparatus capable of encrypting data without affecting the business performance. This storage apparatus includes a cache memory, a first controller for controlling the writing of data in the cache memory pursuant to the write command, a second controller for controlling the writing of the data written in the cache into the storage devices, and an encryption engine for encrypting data pursuant to the write command. When the second controller reads the data from the cache memory and writes the data in said storage devices, the encryption engine encrypts the data, and the second controller writes the encrypted data in said storage devices.

  • Storage system, path management method and path management device
    Patent number: 8223652
    Abstract: Proposed are a storage system, a path management method and a path management device capable of ensuring the processing performance demanded by a user while seeking to improve the access performance from a host system to a storage apparatus. Path switching control for dynamically switching the path to be used by the host system according to the loaded condition of the respective paths between the host system and the storage apparatus is executed; and a path is selected as needed according to a policy containing path switching rules created by a user, and path switching control for excluding the selected path from the target and dynamically switching the path to be used by the host system is executed.
