    摘要: The advanced management module services in a data processing system are configured to determine the system load and provide an input to the early power off warning detection logic that evaluates the power system state to detect a condition when power resources are insufficient to maintain the write caching storage system power within defined acceptable limits. The early power off warning detection logic generates a notification based on the system load and the available power supply resources to maintain maximum availability and reliability characteristics.

    摘要: A method of providing a power failure warning in a storage system includes partitioning early power off warning (EPOW) control logic of a storage enclosure to be symmetric with a power distribution network power domain. A power failure warning system for a storage system having a plurality of storage enclosures includes a power system control module coupled to a power supply for control and management of input power to the storage system. An output stage of the power supply is dedicated to a first virtual storage enclosure within one of the plurality of storage enclosures.

    摘要: A storage system includes a RAID adapter, disk array switches, sub-processors, and hard disk drives. A disk-related operation is initiated in the RAID adapter which dispatches a command to a disk array processor (or sub-processor) in an enclosure for the processor to perform the operation on one or more drives. The adapter may dispatch the command to a processor in a single enclosure through a disk array switch or to processors in multiple enclosures through switches in upstream enclosures. The adapter is then free to perform other functions. The processor commences the specified operation on one or more selected drives. Upon completion of the operation, the results are transmitted by the processor and received by the adapter. Offloading the task to the distributed sub-processors reduces the burden on the RAID adapter, reduces system bandwidth usage, and enables access to other drives to be maintained.

    摘要: Data storage systems and methods and computer program product for managing data storage systems are provided. The system includes at least first and second storage enclosures, each having a plurality of hard disks configured as first and second arrays of disks and an intra-enclosure path between the first and second arrays. The intra-enclosure path is disabled during normal operation of the storage system. Inter-enclosure paths respectively link the first arrays in the first and second storage enclosures and the second arrays in the first and second storage enclosures and are enabled during normal operation of the storage system. The system also includes a controller having a first path to the first array in the first enclosure and a second path to the second array in the first enclosure whereby, during normal operation of the system, the first arrays in the first and second enclosures are configured as a first storage loop and the second arrays in the first and second enclosures are configured as a second storage loop. The controller is configured to detect a failure in the first array of the first enclosure and to enable the intra-enclosure path between the first and second arrays in the second enclosure whereby the second storage loop is reconfigured to include the first array in the second enclosure.

    摘要: A configuration of an array of storage devices compliant with a fiber-channel arbitrated loop (FC-AL) specification includes first and second controllers having integrated first and second SCSI enclosure services (SES) processing devices acting as leader processors. Third and fourth controllers are coupled to the first and second controllers and act as subordinate processors. The third and fourth controllers have integrated third and fourth SCSI enclosure services (SES) processing devices. Each of the SES processing devices synchronizes and merges data to create a single control image for the entire configuration, presenting a single SES instance to a storage device interconnect network and to host controller software.

    摘要: A storage system includes a RAID adapter, disk array switches, sub-processors, and hard disk drives (HDDs). The system permits the isolation of a suspected faulty HDD to allow diagnostics to be performed without impacting operation of the rest of the system. Upon detection of a possible fault in a target HDD, a private zone is established including the target HDD and one of the sub-processors, thereby isolating the target HDD. The sub-processor performs diagnostic operations, then transmits its results to the adapter. A faulty HDD can then be fully isolated and the private zone is disassembled, allowing the sub-processor to rejoin the network.

    摘要: A method, system and computer-usable medium are disclosed for providing management of serial attached small computer system interface (SAS) storage devices. A host computer comprises a storage controller connected to a SAS port expander comprising a plurality of ports that are logically assigned to target storage devices. The device ports of all storage devices physically attached to the SAS port expander are bypassed to remove their logical SAS expander port assignments. The storage controller unbypasses the device ports, allowing it to recognize the presence of all physically attached storage devices. The recognized storage devices are inventoried and storage devices that are not logically assigned a SAS expander port are designated as being spare storage devices. SAS expander ports are logically assigned to the non-spare storage devices and SAS storage operations are performed.

    摘要: A high density storage enclosure houses first and second pluralities of hard disk drives (HDDs). The enclosure may be partitioned into a plurality of virtual enclosures, the first plurality of HDDs being associated with a first virtual enclosure and the second plurality of HDDs being associated with a second virtual enclosure. Configuration of the storage enclosure is performed by an SES processor in the storage enclosure accessing configuration parameters received from an external configuration unit coupled to the storage enclosure. The virtual enclosures may be configured as two (or more) independent virtual enclosures on two (or more) independent fabrics or may be configured in a trunked manner. Power supplies and cooling blowers in the storage enclosure may also be partitioned and assigned to be managed by SES processors in the virtual enclosures.
