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.
摘要翻译：具有SAN和NAS接口的混合型存储系统可以通过独立于NAS功能和NAS负载进行SAN功能的简单硬件实现。更具体地说，存储系统的控制器包括用于接受为文件单元发出的I / O命令的NAS控制器和用于接受为块单元发出的I / O命令的SAN控制器。 NAS控制器将为文件单元发出的I / O命令转换为为块单元发出的I / O命令，并将块单元发出的I / O命令传输到SAN控制器。 SAN控制器根据从SAN或从NAS控制器接收的I / O命令访问存储在磁盘设备中的数据，作为为块单元发出的命令。 NAS和SAN控制器能够独立运行。

摘要： A disk array includes a drive management unit, which is a program for identifying kinds of disk devices and managing different disk devices separately, and a drive management table for storing information to be utilized by the drive management unit. The disk array further includes a program for managing ac-cumulated time of disk devices. The program includes a drive lifetime setting portion for setting lifetimes of drives, a drive start/stop portion for intentionally starting/stopping ATA disk devices, and an operation time measurement portion for measuring accumulated operation time. Since it is necessary to be conscious of difference in reliability and performance among disk devices when forming a RAID, a drive kind notification unit, which is a program for notifying of the kind of a disk device when forming the RAID, is provided.

摘要： A disk array system has a disk storage group, an array controller reading/writing data of the group, a disk interface connecting unit having a plurality of ports for connection with the controller and the group, and a disk interface connection changing unit. In an array configuration information memory, information indicating a relation between the controller and the group is stored. An array configuration changing portion changes the array configuration information in response to a user's request. A connection changing interface informs the changing unit of a connection change based on the changed array configuration information. The changing unit sends instruction information on setting up the connection status among the ports to the connecting unit to establish the configuration indicated by the array configuration information. The connecting unit changes the port connection according to the instruction information sent from the changing unit.

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。
