    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： A storage control apparatus concatenates a plurality of logical units to construct a large capacity logical unit, wherein logical units extending over a plurality of controllers can be concatenated. The channel adapter sends an I/O request to one controller which charges one logical unit constituting the concatenation logical unit, out of a plurality of controllers when an I/O request is sent from a host to the concatenation logical unit LU linking a plurality of logical units, executes I/O processing in the one controller, then sends the I/O request to another controller which charges another logical unit constituting the concatenation logical unit, and continues I/O processing in the another controller.

    摘要： In a data recording apparatus, a monitoring unit detects a VLU including an MRB that manages an area that has not been accessed for a specified time period based on a current time, a time management table, and a parameter table. From MRBs of the detected VLU, the monitoring unit selects a plurality of MRBs with an unaccessed time period equal to or more than the specified time period and equal to or less than a total time. The monitoring unit performs synchronization process for data in a primary storage managed by the selected MRBs at a time. During the synchronization process, a correction value is adjusted when there is a data conflict with another device.

    摘要： A data recording apparatus includes a determining unit that determines whether a storable area is present in the first storage device. The storable area is a combination of a plurality of empty areas having contiguous physical addresses with a total data volume larger than that of a volume of the data. When the determining unit determines that the storable area is present, a first storage unit stores the data in the storable area, and a second storage unit stores the data that has been stored by the first storage unit in the storable area as a lump into the second storage device.

    摘要： When an input/output request of a channel adapter causes a mishit on a cache and a staging amount by a device adapter reaches a predetermined amount, the cache is set into a hit status and the channel adapter is reactivated. By receiving a hit response, the reactivated channel adapter executes an input and an output for the cache and the staging of the channel adapter in parallel. A defective/alternating track management table which corresponds to track data stored in a cache memory and has each of addresses of a defective track and an alternating track and flag information showing a link state between both of the defective track and the alternating track is provided for an input/output controller. For a retrieving request in which the defective track address is designated, the defective/alternating track management table is retrieved and the corresponding alternating track address is obtained, thereby judging the presence or absence of a registration of a hash table.
