    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: A method is disclosed to set the speed of a network. The method supplies a network interconnected with a system controller and a plurality of switch domains, where each of those plurality of switch domains comprises one or more information storage devices and a switch domain controller, and sets by each of the plurality of switch domains a signaling rate for that switch domain. The method queries in-band by the system controller each of the plurality of switch domains for that switch domain's signaling rate, and provides in-band by each of the plurality of switch domains the signaling rate for that switch domain. The method provides in-band by the system controller to each of the plurality of switch domains a first speed selection command specifying a first network speed, and resets by each of the plurality of switch domains the signaling rate for that switch domain to the first network speed.

    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.
