    摘要: A method is disclosed to provide power to a plurality of data storage devices disposed in a data storage system. The data storage system comprises a system controller comprising a data storage device power-up algorithm and a plurality of data storage devices, where each of the plurality of data storage devices cannot automatically provide a device present signal. The method detects the presence of each of the plurality of data storage devices, and then provides power to each of the detected data storage devices using the data storage device power-up algorithm.

    摘要: A storage system in which a set of a data block and a redundancy block is stored has a plurality of control sections which respectively control a plurality of storages, a host connection unit which selects the control section controlling one of the storage in which a write data block which is a write-object block is to be stored, and a transfer unit which transfers the write data block to the control section. Each of the plurality of control sections includes a data block write section which writes the write data block transferred by a transfer unit to the storage in which the write data block is to be stored, a redundancy block update request section which requests the control section controlling the storage in which a redundancy block is to be stored to update the redundancy block, and a redundancy block update section which updates the redundancy block stored in the storage controlled by the control section when another of the control sections makes a request for updating the redundancy block.

    摘要: A serial SCSI (SAS) storage drive system includes a drive enclosure having a first interface card coupled to one storage controller over a single SAS path and a second interface card coupled to another storage controller over a different single SAS path. At least one disk drive within the enclosure is assigned to the first storage controller and interconnected to the storage controller through the first interface card. At least a second disk drive within the enclosure is assigned to the second storage controller and interconnected to the storage controller through the second interface card. The interface cards are selectively interconnected with each other through a crossover port. In the event of a failure in a storage controller or an interface card, the crossover port may be activated, thereby maintaining access to both sets of disk drives.

    摘要: A system provides communication between components of a computer data storage system using out-of-band (OOB) signaling. The system includes a plurality of data storage devices having a local controller for directing data flow to each of the plurality of data storage devices. A switch is coupled to the local controller to direct data to the set of the plurality of data storage devices. First and second initiators are coupled to the switch. The first initiator communicates the OOB signals through the switch alternatively to the local controller or to the second initiator.

    摘要: When data are transferred to a cache from disk drives, through a back end I/F unit, a redundant code verifier of a data path controller compares write-history information (a Destaging Counter (DC) value) embedded in a redundant code of the data with a DC value embedded in a redundant code of a corresponding parity, thereby verifying whether the data are imprecise. In addition, in a case where the data are updated, the redundant code verifier makes a similar verification when old data to be used for creating a parity are read. When the data are not imprecise, a redundant code generator of the data path controller adds to new data and the parity a redundant code into which a new DC value has been embedded. When the data are imprecise, a controller informs a host of an occurrence of a problem through a front end I/F unit.
