  • Patent number: 7747792
    Abstract: In accordance with an embodiment of the present invention, an assistance mechanism tracks a plurality of time intervals between a plurality of input events. Each input event of said plurality of input events is generated by a user physically manipulating an input device at a client. Based on the plurality of time intervals, the assistance mechanism dynamically determines a threshold period. Then the assistance mechanism determines whether a subsequent input event has been generated within said threshold period. In response to determining that an input event has not been generated within said threshold period, the assistance mechanism may cause information to be displayed at the client.

  • Patent number: 7747799
    Abstract: Data transfer is performed to and from a host computer using a first block as the minimum unit. Data transfer is performed to and from a storage area using a second block as the minimum unit. A second block set of the storage area stores data obtained from performing data conversion processes that change the size of the data itself, with a first block set as the unit. Here a correspondence relationship is generated between the first block set and the second block set. In response to a read request from the host computer, a second block set, which corresponds to the first block set that includes the first block that is requested, is read, a reverse-conversion process is performed, and the data is sent to the host computer.

  • Patent number: 7743171
    Abstract: Described is a technique for initialization of a device in a data storage system. A status indicating completion of the initialization is returned after setting initialization indicators associated with tracks of the device. The indicators indicate that the tracks of the device are to be initialized. As subsequent I/O operations for the device are processed, the tracks associated with the subsequent I/O operations are initialized prior to performing the I/O operation if the initialization indicators associated with the tracks are set. A background initialization task scans the initialization indicators and initializes tracks in accordance with the initialization indicators. Once a track has been initialized, its associated initialization indicator is cleared.

  • Patent number: 7743178
    Abstract: A system for enabling SATA drives to be utilized in FC SANs is disclosed. To send data to a SATA drive over a FC SAN, a host sends SCSI commands encapsulated in FC frames over a standard FC link to a Fibre Channel Attached SATA Tunneling (FAST) RAID controller, where the SCSI commands are de-encapsulated from the FC frames and translated to SATA FISs. The SATA FISs are thereafter encapsulated into FC frames. The IOC that performs these functions is referred to as a FAST IOC. The SATA-encapsulated FC frames are sent to multiple disk drive enclosures over another standard FC link. The FC frames are de-encapsulated by FAST switches in disk drive enclosures to retrieve the SATA FISs, and the SATA FISs are sent to the SATA drives over a SATA connection.

The method may further include performing a logical operation between the contents of the interrupt status register and an interrupt mask of a plurality of interrupt masks, the plurality of interrupt masks stored in a second memory. The method may also include processing the plurality of data packets based on the logical operation and incrementing an interrupt mask address pointer stored in a third memory, thereby pointing to another interrupt mask of the plurality of interrupt masks. Of course, many alternatives, variations and modifications are possible without departing from this embodiment.

  • Patent number: 7739422
    Abstract: A method, system and computer program product for eliminating the latency in searching for contiguous memory space by an IO DMA request of a device driver. Three new application programming interfaces (APIs) are provided within the operating system (OS) code that allows the device driver(s) to (1) pre-request and pre-allocate the IO DMA address range from the OS during the IPL and maintain control of the address, (2) map a system (virtual/physical) address range to a specific pre-allocated IO DMA address range, and (3) free the pre-allocated IO DMA address space back to the kernel when the space is no longer required. Utilizing these APIs enables advanced IO DMA address mapping techniques maintained by the device drivers, and the assigned/allocated IO DMA address space is no longer fragmented, and the latency of completing the IO DMA mapping is substantially reduced/eliminated.

  • Patent number: 7739432
    Abstract: A multi-port switch and a method of command switching using such a switch. Multiple virtual targets provide multiple hosts with access to the physical target device attached to the target interface of the switch. The switch intelligently dispatches operations received by the virtual targets to the physical storage target device to provide shared access. In doing so, the communication between the switch and the physical target can fully comply with the SATA protocol without the physical target being aware that the operations have originated from multiple physical hosts, and without the multiple physical hosts being aware of the shared nature of the physical SATA target device.

  • Patent number: 7739428
    Abstract: For an electronic apparatus in which data is transferred between a plurality of processing devices and a memory, a technique is provided which prevents the data transfer from being restricted and allows the processing devices to operate efficiently. The order of priorities of data transfer operations through channels is changed on the basis of a relation between thresholds and the amounts of data remaining respectively in FIFO buffers. This prevents the FIFO buffers from becoming empty of data, or from being filled up with data, which allows the devices to operate efficiently.

  • Patent number: 7734842
    Abstract: A computer-implemented method, apparatus, and computer program product are disclosed for managing direct memory access (DMA) write page faults using a pool of substitute pages. A computer system platform resolves a DMA write page fault for a page that is dedicated to an Input/Output (I/O) adapter. The I/O adapter attempts to write DMA data to the page. A determination is made that the page is unavailable for writing. The DMA data is then written to data locations in a substitute page that was selected from the pool of substitute pages. A flag is then set in a flag location for each one of the data locations. The flag locations correspond to the data locations. When a flag is set, the flag indicates that DMA write data is present in the data location that corresponds to that flag's flag location.

  • Patent number: 7734830
    Abstract: An information storage device, by which only information outputted in a state desired by a user can be stored and disclosed with minimum time and trouble of the user, is provided. After FAX transmission, the FAX image is displayed and an inquiry concerning whether to store the FAX image or not is conducted. When the user performs an operation designating registration of the FAX image in a database (i.e. when a registration command button is pressed by the user), the FAX image is registered in the database. When the user performs an operation designating discard of the FAX image (i.e. when a discard command button is pressed by the user), the FAX image is discarded. Since the user can decide whether or not to register the FAX image in the database after checking the image to be registered, registration of undesired image in the database can be prevented.
