Abstract: A process and system for virtually managing enclosures. A process determines whether a system includes an enclosure processor, a virtual enclosure processor, or both an enclosure processor and a virtual enclosure processor. The process receives a command by a virtual enclosure processor if it is determined that the system includes the virtual enclosure processor. The virtual enclosure processor manages a peripheral in an enclosure. Additionally, a process activates a virtual enclosure processor in a system including a real enclosure processor. The virtual enclosure processor receives a command. The virtual enclosure processor controls a peripheral.

Abstract: A method and apparatus for detecting soft errors in a storage subsystem is provided. Write data generated for a write operation in a first controller is concurrently generated in a second controller and written to a storage device by the first controller. Soft errors are detected by comparing the two sets of write data by comparing respective checksums or the write data read back from the storage device by the second controller.

Abstract: Apparatus and systems, as well as methods and articles, may operate to sequence write operations and journal a portion of write data in a dual-parity redundant array of inexpensive disks (RAID) sub-system such that one or more parity strips in a stripe are consistent with target stripe data during the write operations, such that the consistency of the parity strips is determinant following an unexpected RAID sub-system reset occurring during the write operations, and such that the parity strips and the target stripe data are recoverable following a disk drive failure and a power failure occurring during the write operations.

Abstract: A method and apparatus establish an address of a frame as being associated with a physical device or a virtual device. If the frame is associated with a virtual device, the address of the frame may be established as being associated with a local virtual device or a remote virtual device. Establishing the nature and location of the device may provide routing by a virtual bridge.

Abstract: A packet is received from a network at an out-of-band (OOB) network interface of an OOB platform switch of a computer system. A destination of the packet is identified. A next hop is determined along a path the packet may be routed to reach the destination. The packet is forwarded to the next hop via the OOB network interface by the OOB platform switch.

Abstract: In one embodiment, a standard block device command is received at a device controller. The standard block device command is addressed to a virtual block device associated with the device controller. The standard block device command is to invoke functionality from the device controller unrelated to the standard block device command. The functionality invoked by the standard block device command is performed by the device controller.

Abstract: The present disclosure includes systems and techniques relating to booting to a network storage target. In general, in one implementation, a bus-to-network device driver is loaded during a machine boot, where the bus-to-network device driver is capable of sending machine bus commands over a network, providing access to the network for a network device driver, and distinguishing between received responses to the machine bus commands and other network traffic corresponding to the network device driver. Loading of the bus-to-network device driver can occur in response to an operating system load of bus drivers. For example, the bus-to-network device driver can be an iSCSI driver, and the operating system load of bus drivers can be the operating system load of SCSI drivers.

Abstract: According to one embodiment, a system is disclosed. The system includes an initiator device to transmit input/output (I/O) write data and a target device, coupled to the initiator device, to receive the write data from the initiator device as a first segment of data and a second segment of data. The target device re-transmits a transfer ready frame to force the initiator device to retransmit the second segment in response to detecting an uncorrectable error in the second segment.

Abstract: Some embodiments include apparatus and method to allocate ports of host bus adapters in computer systems to multiple operating systems in the computer systems. Other embodiments are described and claimed.

Abstract: A distributed data storage system stores a single image file system across a plurality of physical storage volumes. The physical storage may be direct attached storage, or may be coupled through a storage area network (“SAN”). One or more clients communicate with a plurality of storage nodes through a network. A client of the distributed data storage system transmits a request over the network for a file identified in the file system. A load-balancing switch selects one of the storage nodes to process the request. The storage node accesses at least one of the physical volumes and transmits a response for the storage operation to the client.

Abstract: A method according to one embodiment may include discovering at least one ATA/ATAPI target device. The method of this embodiment may also include discovering a SAS address for at the least one ATA/ATAPI target device. The method of this embodiment may also include returning the SAS address for the at least one ATA/ATAPI target device in response to a device inquiry command. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

Abstract: A network storage system includes a virtual file system (“VFS”), to manage the files of the network storage system, and a storage center that stores the files. The VFS and the storage center are separated, such that a client accesses the VFS to conduct file system operations and the client accesses the storage center to upload/download files. The client accesses the network storage system through one or more storage ports. The storage center includes a plurality of distributed object storage managers (DOSMs) and a storage cluster that includes a plurality of intelligent storage nodes. The network storage system includes additional storage centers at geographically disparate locations. The network storage system uses a multi-cast protocol to maintain file information at the DOSMs regarding files stored in the intelligent storage nodes, including files stored in disparate storage centers.

Abstract: Provided are a techniques for mapping data blocks to storage blocks. A portion of data is received, and the portion of data is segmented into one or more data blocks. The one or more data blocks are mapped to one or more storage blocks of one or more storage devices, wherein the one or more data blocks are mapped to wrap around the storage devices after each of the storage devices has been utilized.

Abstract: Conference calls are handled using distributed processing. In one embodiment, the invention includes receiving sets of telephone audio signals from conference subnodes, the telephone audio signals corresponding to subscribers of the conference call, selecting an output set of telephone audio signals from all of the received telephone audio signals, and transmitting the output set to the conference subnodes. In another embodiment, the invention includes receiving a set of telephone audio signals, each signal being received from a subscriber node of a single conference call, selecting a subset of the set of signals, transmitting the selected subset of signals to a conference node, receiving a second set of telephone audio signals from the conference node, and transmitting the second set to the subscriber nodes.

Abstract: An apparatus and method are provided for predictive provisioning of functional packages based on offered traffic and a predictive model of the offered traffic. According to one embodiment of the invention, a managed agent provides predictions regarding an anticipated need for functional package provisioning based on traffic offered to the managed agent and a predictive model of offered traffic. A provisioning agent receives the predictions and in response to the predictions instructs the managed agent to provision a new functional package. According to another embodiment of the invention, the provisioning agent instructs a second managed agent to provision the media resource needed by the original managed agent. The traffic is then routed from the original man aged agent to the second managed agent.
