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.

A data storage library includes a drive enclosure bay which can be adapted to work with multiple air-flow configuration requirements. This is accomplished by creating air-flow ports in the top and bottom of the drive enclosure bay, by forming drive tray slots and printed circuit board ports in associated drive trays, by creating frame ports and PCB notches in associated interface cards, and replacing traditional connectors with slimmer but longer connectors that provide additional standoff and improved air-flow.

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.

An electronics component support assembly and an electronics system assembly employing the component support assembly are provided. The component support assembly includes a rotatable base support and a component connector assembly. The rotatable base support is sized to reside within an electronics enclosure and to operatively support multiple electronics components thereon. The component connector assembly is associated with the rotatable base support, and at least some electronics components of the multiple electronics components couple thereto when operatively supported by the rotatable base support. Rotation of the rotatable base support facilitates access to the multiple electronics components, and the component connector assembly allows for rotation of the rotatable base support with the multiple electronics components operatively supported on the rotatable base support.

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.

A method is disclosed to assign network addresses in a storage array disposed in a data storage and retrieval system comprising (P) data storage devices disposed in (N) data storage device assemblies. The method configures the (N) data storage device assemblies to comprise a spare data storage device assembly and a first storage array comprising (N−1) active data storage device assemblies, wherein each data storage device configured in the first storage array is assigned a network address, and wherein one of the spare data storage device disposed in the spare data storage device assembly is assigned a network address. In the event the method detects a failed data storage device disposed in the first storage array, then the method forms a second storage array comprising the first storage array, except the failed data storage device, in combination with the (i)th spare data storage device.

A method is disclosed to reconfigure a storage array. The method supplies a data storage and retrieval system comprising (N) data storage device assemblies, wherein each of those (N) data storage device assemblies comprises (M) data storage devices, wherein (N) is greater than or equal to 2, and wherein (M) is greater than or equal to 2. The method configures those (N) data storage device assemblies to comprise a spare data storage device assembly and a first storage array comprising the remaining (N−1) data storage device assemblies. In the event Applicants' method detects a failed data storage device disposed in the first storage array, then the method forms a second storage array comprising the first storage array, except the failed data storage device, in combination with a data storage device disposed in the spare data storage device assembly.
