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 disk array system in which the disk array control mode can be switched to a higher-performance mode easily by exchanging extension boards. An IF board is parallel-connected to disk devices through signal lines. Several types of extension boards each having a controller in accordance with the access control mode are prepared so that one of the extension boards is connected to the IF board through a connector formed as a set of one internal bus connector, a plurality of SCSI connectors and extension board type identification pins. As a result, it is not necessary for a user to alter the connection of disk drives and to switch control software on the host computer, so that the disk array control mode can be changed to a higher-performance mode easily only by exchanging the board.

摘要： In a computer system having a host system including a plurality of disk devices, a CPU, a main memory and a disk control circuit for controlling the disk devices, a host CPU executes a program unit to generate intermediate data for parity generation and holds it in a data holding unit to asynchronously conduct a data write process and a parity write process. A unit for generating parity and a unit for transferring data operate without the intervention of the CPU in accordance with a command issued by the program unit executed by the host CPU.

摘要： A computer system which includes a host machine having a memory and a CPU with an interrupt handling feature, an auxiliary memory unit for recording and reproducing data and an input/output unit for permitting data input and output between the host machine and the auxiliary memory unit. The CPU of the host machine generates a plurality of commands for designating access to the auxiliary unit, in response to at least one command, groups a plurality of the commands for designating access to the auxiliary memory unit, into at least one group and supplies the input/output unit with the commands independently of one another. The input/output unit executes access to the auxiliary memory unit as designated by each of the commands of one group supplied independently of one another by the CPU, and notifies the CPU by a single interruption that execution of the commands of the one group has been terminated when the accesses designated by all commands belonging to the one group have been terminated.

摘要： A clustered storage system includes a plurality of nodes and a management server that consolidates physical position information concerning data in each of the nodes. The management server includes a process to relate the information to the configuration of the clustered storage system and the configuration of each node and present such relations. Each node has a process to obtain the size and load of resources that are used in processing. The management server has a process to collect and tally such resource usage status from each node, and a process to relate the resource usage status, the data information and configuration information to each other and present the relations in a hierarchy. The clustered storage system has a process to move logical volumes among nodes in a manner transparent to the host computer. The management server has a process to support the selection of source data and destination physical position through information display, and a process to receive instruction for such move and to direct the clustered storage system of such move.

摘要： A storage system 1 including multiple slots for loading a block I/O interface controller, a file I/O interface controller, and any other kinds of interface controllers that are combined freely. The storage system 1 includes a management table that manages fail-over-enabled devices by grouping those devices in accordance with the interface type and the domain to which each device belongs; an information table that directs a fail-over procedure; and fail-over controlling means that takes over the processing of a failed interface controller belonging to a fail-over-enabled group. The fail-over system offers several modalities for monitoring failures, selecting takeover controllers and restoring functionality. Storage system 1 solves conventional problems by providing a system that can mount a plurality of file systems, and that resists multiple failures detected in a fail-over server.

摘要： An administrator is required to prepare in advance LU as a pool area when a user storage area is set to a storage. LU configuration is generally cumbersome and it is not easy for a general user to configure it. A pool manager 1 and a storage 1 setting utility in a management console 1 communicate with a program in a storage 1. The storage 1 sets a pool area having a designated capacity. In response to a volume forming request from the management console 1, the storage 1 sets a designated volume by setting the designated volume as a used capacity of the set pool area. When a volume is formed, a policy is designated to select a storage area having a corresponding attribute from the pool area.

摘要： A host computer is connected with a magnetic disk storage device by a SCSI bus. In the magnetic disk storage device, a plurality of partitions are set in a disk drive unit and have device identifiers (IDs) respectively allocated thereto as SCSI IDs=1, 2 and 3, which are supported by a disk controller. When the host computer has acquired the control, the SCSI bus through an arbitration and has selected, for example, the partition with the device identifier SCSI ID=1, the disk controller permits the host computer to access the partition in response to the selection. Since the partitions are different in attributes, properties etc., they seem to be magnetic disk storage device that are separate from one another when viewed from the host computer. Thus, the single magnetic disk storage device can be managed as a plurality of storage devices of different nature.
