    Abstract: In a storage control apparatus provided therein with a battery-backed-up memory device being a combination of a cache memory of a storage device and a system memory on the side of a CPU, an ASIC (Application-Specific Integrated Circuit) having a virtual window function is provided to a system, and I/O from a front end and/or a back end is performed via a virtual window, thereby making an addition of data integrity code, and performing automatic dual write of data. With such a storage control apparatus provided therein with a battery-backed-up memory being a combination of a CS/DS (Code Storage/Data Storage) and a cache, implemented are protection of block data, and dual write into a Cache (user data, control data) so that the reliability can be kept at the time of data input/output control.

    Abstract: A storage system (100) using flash memories includes a storage controller (SC) and plural flash memory modules (Pxx) as storage media. Each flash memory module includes at least one flash memory chip (MEM) and a memory controller (MC) for leveling erase counts of blocks belonging to the flash memory chip. The storage controller combines the plural flash memory modules into a first logical group, translates a first address used for accessing the flash memory modules belonging to the first logical group to a second address used for handling the first address in the storage controller, and combines the plural first logical groups into a second logical group.

    Abstract: The present invention relates to 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 (EDO-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 EDO in a normal state, "VF 0:0, 1" and "MVP 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 EDO, "VF 1:0, 1" and "MVF 0, 0" are connected by VF mapping. As a result, failover to the second data path is realized.
