    摘要: A system for synchronizing identify indicators in a computer storage subsystem includes a switch module electrically coupled to an initiator module. The switch module implements a queuing scheme, receives an identify command from the initiator module, executes the queuing scheme to synchronize the identify command, and broadcasts the identify command to a target device in the computer storage subsystem. A system for synchronizing identify indicators in a computer storage subsystem includes a switch module electrically coupled to a initiator module. The switch module receives an identify command issued by the initiator module, and invokes a distribution algorithm to serially distribute the identify command to a downstream target device in the computer storage subsystem. A method for synchronizing identify indicators in a computer storage subsystem is also disclosed.

    摘要: The present invention provides a method for allowing a multi-drive tray (MDT) to be interchanged with a battery backup unit (BBU) tray within a disk enclosure blade (DEB) of a blade server. The DEB is implemented comprising a plurality of controller cards and a plurality of MDTs. One of the MDT slots within the DEB is configured to be interchanged with a BBU tray. The BBU tray is designed to include multiple BBUs and is configured to have packaging, mounting, and air flow characteristics that are similar to an MDT. In one embodiment, a controller card queries each MDT slot within the DEB and determines if any of the queried MDT slots contain a BBU tray. If a queried MDT slot contains a BBU tray, the controller card manages the queried MDT slot as a BBU slot. Otherwise, the controller card manages the queried MDT slot as an MDT slot.

    摘要: A system migrates data between a source device and a target device in a storage system. A processor is operational within a local domain of the storage system. A redundant array of independent disks (RAID) controller electrically connected to the processor. The RAID controller divides a capacity of the source device into a plurality of sub-regions, locks the sub-regions from storage activity, establishes a mirroring relationship for write data updates between the source device and target device, and assigns the processor to copy data from the source device to the target device. A method of migrating data includes dividing a capacity of a source device into a plurality of sub-regions, locking the sub-regions from storage activity, establishing a mirroring relationship for write data updates between the source device and a target device, and assigning a local processor to copy data from the source device to the target device.

    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: A method to assign addresses to a plurality of data storage devices, by providing a switch and (N) data storage devices, where each of those (N) data storage devices is interconnected with said switch. The method further establishes (M) arbitrated loop physical addresses (“AL_PAs”), where (M) is less than (N), and assigns a different one of each of the (M) AL_PAs to a different one of the (N) data storage devices, such that the (N) data storage devices comprise (M) AL_PA-assigned data storage devices and (P) non-address-assigned data storage devices. The method then detects a failure of an (i)th AL_PA-assigned data storage device, and transfers the (i)th AL_PA from the failed address-assigned data storage device to a (j)th data storage device, where that (j)th data storage device comprises one of the (P) previously non-addressed data storage devices.

    摘要: A method provides for dynamic data logging in a storage subsystem. The method determines if a plurality of storage devices has been assigned as a plurality of hot spare devices in the storage subsystem. If the plurality of hot spare devices are assigned, the method determines from the plurality of hot spare devices whether a plurality of storage types with a maximum number of spare devices is present. If a plurality of storage types is present, the method selects a hot spare device from a storage type having the smallest capacity to assign as a logging device, otherwise, the method calculates a plurality of ratios of a first number of storage devices of a shared storage type to a second number of storage devices to which the first number of storage devices can act for as hot spare devices, selecting a storage device with the lowest ratio as the logging device.
