摘要： A fault-tolerant storage system is provided. The storage system is composed of a controller having a plurality of processors and other units. When an error occurs in any one of the components in the controller, the storage system cuts off an I/O path of the controller, specifies the failed component in the cutoff status, and invalidates the failed component. After invalidating the failed component, the storage system determines whether it is operable only with the normal components, cancels (releases) the cutoff of the I/O path when it determines that it is operable, and resumes operation by rebooting.

摘要： The present invention provides means for effectively reducing the amount of data by means of de-duplication in a disk array apparatus having a data guarantee code. A control means for the disk array apparatus that adds a data guarantee code to each logical data block and checks the data guarantee code when reading data has a de-duplication performing function and control means for: generating LA substitution information for a function checking the data guarantee code or read data location address substitution information when performing the de-duplication and storing data; performing the de-duplication using the above-mentioned information when reading data; and thereby avoiding false diagnosis of the data guarantee code check.

摘要： A storage device in which the MR-IOV is applied to an internal network of a storage controller. Data path failover can be executed in the storage device. The internal network of the storage controller is configured to enable the access of a virtual function (VF) “VF 0:0, 1” of each endpoint device (ED0-ED2) from a root port RP0. Likewise, “VF 1:0, 1” of each endpoint device can be accessed from a root port RP1. In a first data path from the RP0 to ED0 in a normal state, “VF 0:0, 1” and “MVF 0, 0” are connected by VF mapping. When a failure occurs on the first data path, the MR-PCIM executes the VF migration, whereby in the second data path from the RP1 to ED0, “VF 1:0, 1” and “MVF 0, 0” are connected by VF mapping. As a result, failover to the second data path is realized.

摘要： A storage system is arranged to speed up the operation and easily duplicate data without the capacity of the cache memory being so large even if lots of host computers are connected with the storage system. This storage system includes channel adapters, disk drives, disk adapters, and network switches. Further, the front side cache memories connected with the channel adapters and the back side cache memories connected with the disk adapters are provided as two layered cache system. When a request for writing data is given to the storage system by the host computer, the data is written in both the front side cache memory and the back side cache memory. The write data is duplicated by placing the write data in one of the front side cache memories and one of the back side cache memories or two of the back side cache memories.
