    摘要: A cache managing unit creates a list of elements corresponding to each data block arranged based on a priority of writing data blocks to a magnetic disk apparatus, and when a group of elements corresponding to data blocks to be written to the same magnetic disk apparatus exists, provides a link connecting elements at both ends of the group. A write control unit searches, upon selecting a data block for writing, elements belonging to the list in descending order of priority, and if a link is set at an element corresponding to a data block to be written to a magnetic disk that cannot perform a writing, follows the link to search a subsequent element.

    摘要: An interdevice communication monitoring unit 62-1 calculates a variable timeout time (T2−T) by subtracting an elapsed time T from a predetermined fixed timeout time T2 for monitoring an intermodule communication to monitor an elapsed time of an intermodule communication. The fixed timeout time T2 is a time shorter than a predetermined interface connection check time T1 for monitoring an interface connection with a channel. When the elapsed time T of the intermodule communication exceeds the variable timeout time (T2−T), the interdevice communication monitoring unit requests a channel to separate the interface connection, and then when an end response is obtained from a control module, requests the channel for an interface reconnection and then transmits an end response.

    摘要: A storage system prevents a time out error of the host I/O caused by a stagnation of command processing in the storage system for accessing a disk device according to the host I/O request and internal I/O request. In DTC, counters for managing the requests in-process for host I/Os (host read) and internal I/Os (pre-fetch, write back) individually are provided, and the number of processing requests to be issued to a virtual disk (RLU) is limited individually. By assigning priority to the host I/Os, the load balance of the host I/Os and internal I/Os can be controlled. For rebuild/copy back, a dedicated load control mechanism is disposed where the load adjustment between ordinary I/Os and rebuild/copy back is performed.

    摘要: In the present invention, for each set of blocks [#(0) to #(N-1)] storing update data, a history block [#(N)] storing an update state value, for example, a generation, time or check code, showing an update state is provided, constituting a set of management data as a check object. When writing update data on a disk, a new update state value is calculated for the same set of management data and stored in memory as update state confirmation value. The new update state value is also set as write data in the history block in the same set of management data, and the entire of the set of management data including update data and update state value are written onto a disk. The history block is read and disk write omissions are detected by comparing the update state value and the update state confirmation value stored in memory.
