    摘要: A RAID system performs host I/O processing during RAID formatting of a plurality of physical disk drives. The controller executes sequential format processing and one-point format processing. A RAID format writing size (SFS) for sequential format processing is set larger than a RAID format writing size (OFS) for one-point format processing. Delay of host I/O processing is reduced, so that the time required for RAID formatting can be shortened.

    摘要: A system creates a configuration definition table to be used for accessing a physical disk according to a host I/O request, to decrease a memory size of the configuration definition table even if common firmware is used for models with different scales. For this, a model correspondence table to show the definition of each model is provided in a configuration setup processing module, the maximum values of this model are recorded in a memory based on this content, and a memory area for each item is secured. And the actual content of the configuration definition is developed on the secured memory. Therefore even for a diversity of models, the memory size of the configuration definition table can be decreased to a size matching the model, with common firmware regardless the model.

    摘要: A RAID-group converting apparatus converts two RAID groups into one RAID group. The RAID-group converting apparatus includes: a data-reading unit that reads at least non-parity data from data including the non-parity data and parity data, for each stripe from a plurality of recording media belonging to the two RAID groups; a parity-generating unit that generates two parities using the data belonging to a same stripe read by the data-reading unit; and a parity-writing unit that writes the two parities generated by the parity-generating unit into a parity storage area belonging to the same stripe.

    摘要: When receiving a notification of an error detected by patrol processing of the device adaptor for a secondary disk apparatus, a first recovery processing unit reads out data corresponding to the error location from a normal primary disk apparatus and writes the data into the error disk apparatus to eliminate the error. If it is determined that the content of the error notification is abnormality of the block ID which is an identifier of the order of writing data, a second recovery processing unit retrieves a correct write address indicated by the identifier, compares data of the error disk apparatus with that of the normal disk apparatus, determines that a lost write exists in the case of mismatch, and eliminates the lost write by writing the data read out from the normal disk apparatus into the error disk apparatus.

    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.
