  • Patent number: 6993603
    Abstract: A model in which filter drivers are managed to receive callbacks for I/O requests in which the filter drivers have registered an interest. Per-volume instances of filter drivers register with a filter manager for pre-callbacks (for I/O to the file system) and post-callbacks (for I/O from the file system), and identify which I/O requests (e.g., create, read, write) they are registering to receive callbacks. The filter manager orders the instances for callbacks. When an I/O request is received, the filter manager converts the I/O request to callback data and calls the interested filters in the callback order, whereby the filter instances can process the I/O data. As the request returns from the file system, filters desiring post callbacks are called in the reverse order. Efficient context management for the filters and other functions, such as non-reentrant file I/O, are also provided by the model.

  • Patent number: 6985974
    Abstract: A network device receives data packets from a network adaptor. A low latency memory has a first read/write performance. A high latency memory has a second read/write performance that is slower than the first read/write performance of the low latency memory. An interface controller uses an address check circuit and values stored in registers to determine whether a read or write operation relates to header portions of the data packets. The interface controller stores header portions of the data packets in the low latency memory and data portions of the data packets in the high latency memory. The registers include base address, buffer pool size, maximum individual buffer size, and header size registers. Alternately the registers include base address, mask, maximum individual buffer size, and header size registers.

  • Patent number: 6954807
    Abstract: The address of a data packet to be transferred from a memory to a network interface card within a direct memory access (DMA) is checked. First of all, the address of a descriptor corresponding to the data packet is read from the memory, wherein the descriptor contains information of the address of the data packet. Then, whether the address of the descriptor complies with a certain rule is determined. If the address of the descriptor does not comply with the certain rule, an interrupt signal is asserted to a processor to perform a corresponding interrupt service in order to re-read the address of the descriptor.

  • Patent number: 6928494
    Abstract: A method and apparatus for communicating commands and/or data between two different time domains. In one embodiment, multiple memory commands are placed into one or more FIFOs in a manner that specifies the delays that must take place between execution of the different commands. Along with the commands, delay information is placed into the FIFOs, specifying the number of clock cycles, or other form of time delay, that must elapse between execution of a command and execution of a subsequent command. This delay information is used to delay the execution of the subsequent command for the specified time period, while minimizing or eliminating any excess delays. Cue information can also be placed into the FIFOs with the commands to specify which commands must wait for other commands before beginning execution. The delay and cue information is determined and created in the time domain that initiates the transfers. The delays and cueing are executed in the other time domain.

  • Patent number: 6912604
    Abstract: A host channel adapter configured for outputting packets according to InfiniBand™ protocol is implemented using partitioned link modules configured for performing selected link operations prior to outputting the packets. A pre-link module is configured for ordering work queue entries in an order based on determined service level and virtual lane priorities. The pre-link module outputs the ordered work queue entries to a transport service module configured for generating a transport layer header for the packets based on the respective work queue entries. Once the transport layer headers have been generated, a post-link module is configured for retrieval of the transport layer header and transport data and preparing the transmit data packets for transmission on the network by constructing the link layer fields. The post-link module outputs the transmit data packets based on the ordering and the flow control protocol for the appropriate virtual lanes.

  • Patent number: 6895455
    Abstract: A disk drive is disclosed that is responsive to standard disk-drive commands associated with disk-drive operations and to nonstandard disk-drive commands required for disk drive manufacture and quality testing. The disk drive includes a disk, a head actuated radially over the disk, and a disk control system. The disk control system responds to disk-drive commands and accesses data storage locations on the disk through the head. A serial ATA interface couples the disk control system to a host computer. The serial ATA interface is configured to transfer standard disk-drive commands from the host computer to the disk control system and is configured to not transfer nonstandard disk-drive commands from the host computer to the disk control system. The extracting means extracts a nonstandard disk-drive command that is embedded within a data block accessed using a standard disk-drive command and provides the extracted nonstandard disk-drive command to the disk control system.

  • Patent number: 6892255
    Abstract: A method of installing a program or renewing a file. A first program or file stored on a first memory area is copied to a second memory area. Position-information memory area is updated with position information indicating a location on the second memory area where the first program or file is copied or stored. Then, a second program or file is written into the first memory area, and the position-information memory area is updated again with position information indicating a location on the first memory area where the second program or file is written. With use of the above method, even though an unexpected error should occur during the course of installing the second program or file, the original program or file can be immediately recovered. An easy to use method of installing a program or renewing a file is provided, which reduces burden of time consuming operation by a user.

  • Patent number: 6889272
    Abstract: A system and method for transmitting parallel data from a source to a destination over a plurality of high speed serial lines operates reliably even in the presence of data skew. The high speed data transmission system includes a protocol generator, a de-skew circuit, and a plurality of high speed serial lines coupled between the protocol generator and the de-skew circuit. Respective serial representations of parallel data words are transmitted to the destination over a plurality of serial data lines, and a clock signal is transmitted to the destination over a clock line in parallel with the serial data lines. The clock signal has at least one data bit of each parallel data word encoded thereon. The de-skew circuit aligns regenerated parallel data words using the respective data bits encoded on the clock signal to eliminate skew among the data bits, and regenerates the parallel data from the aligned parallel data words.
