摘要： Disclosed is storage system, that is, an array-type disk apparatus which is provided with an error monitor section which monitors the status of error occurrence in a disk drive and instructs initiation of mirroring between the disk drive and a spare disk drive when the number of errors occurred of the disk drive exceeds a specified value, and a mirror section which performs mirroring between the disk drive and spare disk drive. Storage system, that is, the array-type disk apparatus may be provided with an error monitor section which monitors the status of error occurrence in a disk drive and gives such an instruction as to set the status of the disk drive in a temporary blocked state, and a data restoring section which executes data restoration by reading data from the temporary blocked disk drive when reading from another disk drive constituting a disk array group is not possible during data restoration.

摘要： In a disk array system, data read out and data written anew are temporarily held as former data in a former data holding portion. When a write operation has occurred, a CPU searches the holding portion for write data, it generates update data from the new and former write data items, and it holds the generated update data in an update data holding portion. In addition, the CPU stores the storage address of redundant data associated with the held update data, as log data in a log data holding portion. Further, the CPU operates asynchronously with the write operation to read out the redundant data of the address of the holding portion, to calculate new redundant data from the read redundant data and the held update data, and to write the new redundant data into the address of the log data. On this occasion, a parity area and a data area are separated so as to heighten read/write processing speeds and a parity generation processing speed.
摘要翻译：在磁盘阵列系统中，数据读出和重新写入的数据被暂时保持为前一数据保存部分中的前一数据。当发生写入操作时，CPU在保持部分中搜索写入数据，它从新的和先前的写入数据项生成更新数据，并且将生成的更新数据保存在更新数据保存部分中。此外，CPU将与所保持的更新数据相关联的冗余数据的存储地址作为日志数据存储在日志数据保持部分中。此外，CPU与写入操作异步地读出保持部分的地址的冗余数据，从读取的冗余数据和保持的更新数据计算新的冗余数据，并将新的冗余数据写入地址的日志数据。在这种情况下，分离奇偶校验区域和数据区域，以便提高读/写处理速度和奇偶校验生成处理速度。

摘要： A storage system having a plurality of disk controllers for accepting computer access through a SAN, and a plurality of file servers for accepting computer access through a LAN. The disk controllers and file servers are connected through a connection unit to a plurality of disk drive units in a disk pool. A disk pool management unit manages the relationships between the disk controllers and file servers and the disk drive units used by the respective disk controllers and file servers, and sends information identifying the usable disk drive units to the respective disk controllers and file servers. The disk controllers and file servers use the disk drive units based on the received usable disk information.

摘要： A hybrid-type storage system having both SAN and NAS interfaces can be implemented by simple hardware capable of carrying out a SAN function independently of a NAS function and a NAS load. To be more specific, a controller of the storage system comprises a NAS controller for accepting an I/O command issued for a file unit and a SAN controller for accepting an I/O command issued for a block unit. The NAS controller converts an I/O command issued for a file unit into an I/O command issued for a block unit, and transfers the I/O command issued for a block unit to the SAN controller. The SAN controller makes an access to data stored in a disk apparatus in accordance with an I/O command received from the SAN or from the NAS controller as a command issued for a block unit. The NAS and SAN controllers are capable of operating independently of each other.

摘要： A storage system includes a disk controller and a disk device having original volumes for backup and a storage pool for backup data. It incorporates a differential management program which checks whether the original volumes for backup are updated or not; a pool management program which allocates a disk area to the storage pool for backup data; a performance management program which manages the performance of each volume; and a backup control program which performs total backup control. A backup method by which recovery within a user-specified recovery object time is possible is selected according to the restore performance calculated by the performance management program and the total size of changed blocks after backup acquisition as counted by the differential management program.
