摘要： A nonvolatile semiconductor storage system has multiple nonvolatile semiconductor storage media, a control circuit having a media interface group (one or more interface devices) coupled to the multiple nonvolatile semiconductor storage media, and multiple switches. The media interface group and the multiple switches are coupled via data buses, and each switch and each of two or more nonvolatile chips are coupled via a data bus. The switch is configured so as to switch a coupling between a data bus coupled to the media interface group and a data bus coupled to any of multiple nonvolatile chips that are coupled to this switch. The control circuit partitions write-target data into multiple data elements, switches a coupling by controlling the multiple switches, and distributively sends the multiple data elements to multiple nonvolatile chips.

摘要： A storage apparatus is provided with a plurality of nonvolatile semiconductor storage media and a storage controller that is a controller that is coupled to the plurality of semiconductor storage media. The storage controller identifies a first semiconductor storage unit that is at least one semiconductor storage media and a second semiconductor storage unit that is at least one semiconductor storage media and that is provided with a remaining length of life shorter than that of the first semiconductor storage unit based on the remaining life length information that has been acquired. The storage controller moreover identifies a first logical storage region for the first semiconductor storage unit and a second logical storage region that is provided with a write load higher than that of the first logical storage region for the second semiconductor storage unit based on the statistics information that indicates the statistics that is related to a write for every logical storage region. The storage controller reads data from the first logical storage region and the second logical storage region, and writes data that has been read from the first logical storage region to the second logical storage region and/or writes data that has been read from the second logical storage region to the first logical storage region.

摘要： One storage area is selected from two or more storage areas of a high load physical storage device, a physical storage device with a lower load than that of the physical storage device is selected, and it is judged whether the redundancy according to the RAID level corresponding to the logical volume decreases when the data elements stored in the selected storage area are transferred to the selected low load physical storage device. If the result of this judgment is that the redundancy does not decrease, the data elements stored in the selected storage area are transferred to a buffer area of the selected low load physical storage device and the logical address space of the logical volume that corresponds to the selected storage area is associated with the buffer area.
