In one example, a separator can be wrapped around the second layer of twisted pairs, and before the inner shield, to assist in meeting the SCSI electrical requirements. In another example where the separator is not used, it is preferred that each wire in the first layer and the second layer has a respective first layer insulation and a second layer insulation, and the second layer insulation is configured to be thicker than the first layer insulation.

摘要： Disclosed is a host adapter having automatic termination, and a method for implementing the automatic termination. The host adapter includes a first connector for connecting to at least one external peripheral device and a second connector for connecting to at least one internal peripheral device. The host adapter further includes a termination system circuit that is coupled between the first connector and the second connector. The termination system circuit is configured to produce bit data that is indicative of whether a peripheral device is coupled to one or both of the first connector and the second connector. Preferably, the termination system circuit communicates the bit data to a software termination engine upon boot-up to enable or disable a termination of the host adapter. Furthermore, the termination system circuit includes a termination control decoder and a tri-state buffer. The host adapter also includes a termination over-ride control that is configured to over-ride the automatic termination generated by the termination system circuit via a software control.

摘要： A hardware accelerated memory system in a hardware accelerated I/O data processing engine that gathers and maintains pointers to a set of widely distributed source and/or destination data locations. The locations of the source and/or destination data locations operated on by the I/O data processing engine can include a memory local to the command interpreter and a memory remote from but accessible to the command interpreter by way of an I/O bus. Each source and/or destination scatter/gather list contains pointers to actual data locations that are either in a memory local to the command interpreter or a memory remote from the command interpreter but accessible by way of an interconnecting I/O bus. Each data location entry in a scatter/gather list is also accompanied by a byte count indicative of the total number of bytes at a given data location.

摘要： A backup mechanism enables incremental backup operations for on-line files of a computer system having an archive bit attribute associated with each file. The mechanism comprises an archive bit change number (ABCN) attribute that is also associated with each file and that is manipulated by a file system of the computer to reflect a correct value of the archive bit when the file is modified during a current backup operation. The ABCN attribute is incremented each time the file is modified to ensure that the file is accurately copied to secondary backup storage during a subsequent incremental backup operation. The mechanism thus enables reliable on-line file modifications which, in turn, substantially increases the efficiency of the computer system.

摘要： A write synchronization system in a headerless format magnetic disk device. The system transmits encoded synchronization signals containing disk administration information such as servo burst information between a servo controller and other disk controller components such as a hard disk controller and a microprocessor or digital signal processor. The servo controller interprets the disk administration information read from the magnetic disk and sends an encoded signal to the other disk controller components for each servo burst encountered on when reading the disk. The disk administration information in the signals can be verified by comparing the contents of a present signal to the contents of at least one previous signal to determine if a servo burst from a sequence of servo bursts has been missed. A missing servo burst can also be identified by measuring the time interval between signals from the servo controller.

摘要： A circuit such as a host adapter includes a timer capable of detecting time-outs for multiple pending commands. The timer includes a single free-running counter, a first storage for start counts, a second storage for time-out values, a subtractor, and a comparator. The start counts are counts from the counter that are saved when issuing an associated command. The time-out values indicate the lengths of different types of time-out periods. To check whether a command timed out, a start count associated with the command is selected from the first storage, and the subtractor determines a difference between a current count in the counter and the selected start count. The difference is then compared to a time-out value that is selected from the second storage according to the type of time-out. The command timed out if the difference is greater than the selected time-out value. In one embodiment, the second storage includes count registers for time-out values, a multiplexer, and select register that provides a select signal to the multiplexer. The select register contains a value associated with the command, and the number of count registers matches the number of types of time-outs.
