Abstract: A storage controller has an operating system (OS) and power control firmware configured to manage use of battery power during a power outage event. The OS specifies to the power control firmware first and second sets of physical components that should be shed by power control firmware during a two-phase vault process. Upon a power failure, the power control firmware turns off power to the first set of physical components and notifies the OS of the power failure. The OS determines whether to abort or continue the vault process. If the OS aborts the vault process, the power control firmware restores power to the first set of physical components. If the OS continues the vault process, the power control firmware turns off power to the second set of physical components, the OS saves application state, and moves all data from volatile memory to persistent memory.

Abstract: A data storage system includes a first chassis that has a pair of storage processors, a pair of SAS expanders having a bidirectional front end port and a plurality of bidirectional backend ports, and an expansion port, a pair of SAS controller each one being coupled between a corresponding one of the pair of processors and a corresponding one of the pair of the expanders, and a first plurality of multiplexers. Each one of the multiplexers has a pair of bidirectional front end ports and a pair of bidirectional back end ports. A first one of the pair of bidirectional front end ports is connected to a corresponding backend port of a corresponding one of the pair of SAS expanders, a second one of the pair of bidirectional front end ports is connected to a corresponding backend port of a corresponding one of the pair of SAS expanders. The first chassis also has a plurality of disk drives, each one being coupled to at least one backend port of a corresponding one of the first plurality of multiplexers.

Abstract: Data storage equipment includes a first storage processor comprising a processing circuit and a collection of packaged integrated circuit devices which has a first set of ports and a second set of ports; a second storage processor; and an interconnect coupled between the first and second storage processors. The processing circuit of the first storage processor is adapted to execute as follows. The collection of packaged integrated circuit devices of the first storage processor is configured to provide (i) communications to a set of storage devices through the first set of ports of the collection of packaged integrated circuit devices and (ii) other communications to the second storage processor through the second set of ports of the collection of packaged integrated circuit devices. Communications is passed between the first storage processor and the set of storage devices through the first set of ports of the collection of packaged integrated circuit devices.

Abstract: An improved data storage system has a set of storage devices, a first storage processor and a second storage processor for storing data into and retrieving data from the set of storage devices. The first storage processor includes a processing circuit and a packaged IC device which has a first set of ports and a second set of ports. The processing circuit is adapted to configure the packaged IC device to provide (i) communications to the set of storage devices through the first set of ports and (ii) other communications to the second storage processor through the second set of ports. The processing circuit is further adapted to pass communications between the first storage processor and the set of storage devices through the first set of ports; and pass communications between the first storage processor and the second storage processor through the second set of ports.

Abstract: A portable display unit includes a serial port to connect to a device such as a vacuum network controller, cryopump, turbomolecular pump, gauges or compressor. In particular, the display unit can be plugged and unplugged to devices of different types. The portable display unit includes a display and control keys for programming, controlling and monitoring the functions of a device. The device accessible to the display unit includes a display interface having software code and files to interface with the display unit. Accordingly, the portable display unit can be used with any device having software code to interface with the display unit. The software code generates, refreshes and communicates menus to the portable display unit to provide graphical interface of the device's functions. The portable display unit further includes inner and outer hand grips so that the display unit can be held by hands of different sizes.

Abstract: A system and method is disclosed in which service dispatch data records are generated and sorted for display. Service dispatch records are generated from data in a product database and a service provider database. A dispatch generation tool generates the service dispatches, and a service dispatch management module sorts and displays the service dispatch data records.

Abstract: A data storage system has a first storage processor, a second storage processor, and a communications subsystem. The communications subsystem has (i) an interfacing portion interconnected between the first storage processor and the second storage processor, (ii) a clock circuit coupled to the interfacing portion, and (iii) a controller coupled to the interfacing portion and the clock circuit. The controller is configured to enable operation of the interfacing portion to provide communications between the first and second storage processors, sense a failure within the clock circuit, and reset the interfacing portion in response to the sensed failure to enable one of the first and second storage processors to continue operation. Such resetting of the interfacing portion prevents the remaining storage processor from locking up, thus freeing that storage processor so that it is capable of continuing to operate even after the failure.

Abstract: Described is a midplane-less data storage enclosure having a control board module with an electrical connector and a bulkhead assembly with a plurality of spaced-apart disk-drive guides coupled to a bulkhead. The disk-drive guides and bulkhead together define a plurality of disk-drive slots. The bulkhead has connected thereto a plurality of first electrical connectors and a second electrical connector in electrical communication with each of the first electrical connectors. Each slot slidably receives a storage disk drive such that the storage disk drive electrically connects to one of the first electrical connectors. The second electrical connector is electrically connected to the connector of the control board module so that each storage disk drive connected to one of the first electrical connectors is in electrical communication with the control board module.
