摘要： A disk drive array including a controller which provides scatter/scatter (bi-directional scatter/gather) operations between noncontiguous host memory address locations and noncontiguous disk address locations. The host provides a single request to launch a scatter/scatter transfer. The single data request includes a pointer to a list of transfer counts and addresses, the length of the list, and the starting logical address on the disk transfer. Skipped blocks in a scatter/scatter request are specified by data address value of -1, and a no-operation (no-op) request is enqueued for each skipped block. Thus, during reads the controller extends the scattered read from the disk into a single large read of contiguous sectors and suppresses the unwanted data by inserting "no-operation" commands in place of the read commands during the transfer to the host.

摘要： A disk controller which fragments host requests into atomic requests or one cycle operations prior to execution. The disk controller is coupled to a disk array and receives requests from a host CPU. Host requests are fragmented down to atomic operations. This is highly advantageous for error handling because the controller is not required to determine which phase of an operation is being requested, since every operation is single phase. The present invention includes use of fence markers or execution-control markers to "fence" of mark a block of tasks and ensure that the atomic operations are executed in sequence, if necessary. These markers ensure that related sequences of atomic operations are kept together without, for example, possibly disruptive intervening writes.

摘要： Apparatus and method for implementing a local proactive hot plug request/acknowledge scheme is disclosed. In a preferred embodiment, each hot pluggable device installable on a computer bus, such as a SCSI bus, is provided with a physical user interface comprising a mechanical request initiator, such as a button or two-position switch, for allowing a user to generate a hot swap request to a controller associated with the bus prior to actual installation of the device on, or removal of the device from, the bus. Upon receipt of the request, the controller determines whether the requested action may be performed, provides a visual indication of its determination to the user via an LED on the user interface and, if installation or removal is determined to be prudent, performs the hot installation/removal in an orderly manner so as not to adversely affect ongoing system operations.

摘要： An improved read ahead strategy that improves the performance of a disk array subsystem. The disk controller keeps track of the last n reads to the array. If a new read request is received that is adjacent to any of the last n reads, the controller performs a look ahead read because a sequential read may be in progress. The parameter n is preferably set comparable to or greater than the number of maximum independent activites being performed by the computer system. Therefore, in a multithread system, the controller performs a readahead if any one thread is doing a sequential read.

摘要： A drag-reduction system incorporated within an inwardly stepped underside of a boat hull for reducing a degree of water pressure forces exerted upon the boat hull during travel of the boat upon a body of water. A plurality of spaced apart rollers are secured at a generally aft location of the boat hull associated with the inwardly stepped underside and extend in parallel spaced apart fashion and perpendicularly to a longitudinal water flow across the boat hull experienced during propulsion of the hull. An elongate and planar shaped belt of a water impervious material having an established width and defining a continuous extending and closed loop is mounted over the plurality of spaced apart rollers. A first linearly extending location of the continuous belt is recessed within the stepped underside of the hull and a second linearly extending location is in contact with the longitudinal water flow. The second linearly extending location of the belt is capable of being translated in a direction consistent with the longitudinal water flow across the boat hull. A single drive roller or pair of drive rollers associated with the plurality of spaced apart rollers is capable of driving the belt at a velocity equal to or greater than a velocity of the longitudinal water flow traveling along the boat hull.

摘要： A system for reducing the amount of power consumed by a battery operated computer device is disclosed. A microcontroller continuously monitors the activity of at least one I/O device and sets an activity state variable (ASV) associated with the I/O device accordingly. Upon each the expiration of a preselected time period, the microcontroller examines the state of the ASV to determine whether the I/O device was active during the expired time period. If so, the I/O device is caused to operate in a full power mode; otherwise, the I/O device is caused to operate in a reduced power consumption mode. In one embodiment, the I/O device is capable of operating in more than one reduced power consumption mode, in which case, responsive to a determination that the I/O device was not active during the expired time period, the I/O device is caused to operate in the next lowest power consumption mode. In an alternative embodiment, the frequency with which timer interrupts are generated is automatically adjusted after the expiration of each time period.
