    摘要: In a RAID storage system, a parity value is generated. The storage system includes a RAID adapter, a plurality of disk array processors managing corresponding sets of RAID storage drives, and a connecting fabric. The RAID adapter initiates a parity generation operation, parallel instructions are dispatched for the array processors to each generate a partial parity value from data blocks on drives on respective managed RAID storage drives, the partial parity value is received in the RAID adapter from each array processor, and the partial parity values are combined in the RAID adapter to generate a complete parity value. The parity value may be an actual parity block to be stored on a hard disk drive or may be a reconstructed data block in the event of a failed drive.

    摘要: An apparatus to detect a fiber channel miscabling event includes a module configured to identify a connection made between first and second unlike devices in a fiber channel topology. If an unlike connection identified to have been made the module enables an upstream port of the second device, leaving a downstream port of the second device disabled. A method to detect a fiber channel miscabling event includes detecting a fiber channel cable connection configuration, determining whether a connection is made between first and second unlike fiber channel units, and enabling an upstream port of the second fiber channel unit while keeping a downstream port of the second fiber channel unit disabled if an unlike connection is determined to have been made.

    摘要: In a fibre channel, arbitrated loop (FC-AL) network environment, an operating speed of devices within a switch domain within the network is optimized. The FC-AL switch domain is isolated from an attached storage controller, and a first signal is transmitted to each of a plurality of storage devices within the domain. The first signal comprises a request that each storage device transmit inquiry data to a control and management node (CMN) within the domain. In response to receipt of the inquiry data from each storage device, the speeds at which each storage device is operable are identified and an operational speed is then established for the domain. The established speed may be the fastest speed at which all devices can operate. Alternatively, one or more slower devices may be bypassed and the established speed may be the fastest speed at which all remaining devices can operate.

    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 storage system includes a RAID adapter, disk array switches, sub-processors, and hard disk drives (HDDs). A disk-related operation is initiated in the RAID adapter. The RAID adapter 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 the upstream enclosures. The adapter is then free to perform other functions. The processor commences the specified operation on one or more selected drives, either sequentially one at a time or sequentially more than one (or all) at a time. Upon completion of the operation, the results are transmitted by the processor and received by the adapter. Thus, by offloading the task to the distributed sub-processors, the burden on the RAID adapter is significantly reduced, system bandwidth usage is reduced, and access to other drives within the enclosure (as well as within other enclosures) may be maintained. Tasks which may be offloaded in such a manner include, but are not limited to, drive firmware updating, drive scrubbing and secure data erasure.

    摘要翻译: 存储系统包括RAID适配器,磁盘阵列交换机,子处理器和硬盘驱动器(HDD)。 磁盘相关操作在RAID适配器中启动。 RAID适配器将命令分配给机箱中的磁盘阵列处理器(或子处理器),以便处理器对一个或多个驱动器执行操作。 适配器可以通过磁盘阵列交换机将命令分派到单个机柜中的处理器,或通过上游机箱中的开关将命令分配到多个机箱中的处理器。 然后适配器可以自由执行其他功能。 处理器在一个或多个选定的驱动器上开始指定的操作,一次一个依次依次执行,或者一次连续执行多个(或全部)。 操作完成后,结果由处理器传送并由适配器接收。 因此,通过将任务卸载到分布式子处理器,RAID适配器的负担显着降低,减少了系统带宽使用,并且可以维护对外壳(以及其他机箱内)的其他驱动器的访问。 可以以这种方式卸载的任务包括但不限于驱动固件更新,驱动器擦除和安全数据擦除。
