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： 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 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： A serial storage architecture (SSA) storage subsystem which includes an SSA initiator and a series of SSA targets which include disk drives housed in a storage pod and an intelligent backplane of the storage pod which houses the other SSA targets. The intelligent backplane includes a controller, a series of status registers, each indicating status of an operating parameter for the SSA target drives, and a series of control registers, each configured to transmit a respective command to selected ones of said SSA target drives. The controller polls each of the status registers and, based on the contents thereof, determines whether an event relating to the operating parameter has occurred. If so, the controller reports the event to the SSA initiator. The SSA initiator may also control the target drives using the control registers.
