摘要： An automatic enable and disable system and method for a computer interfaced device linkable to an external computer system. Communication occurs when a computer interfaced device has been latched to and inserted into or unlatched and about to be removed from the external computer system. A sensor is coupled to a controller of the computer interfaced device, and a sensor component is coupled to a cam mechanism or other such component of the computer interfaced device. The sensor component is engagable to and disengagable from the sensor. The sensor senses engaging and disengaging of the sensor component respectively thereto and therefrom as the cam mechanism or such component is latched and unlatched. Latching of the cam mechanism or such component and the computer interfaced device is communicated to the external computer system when the sensor component is engaged to the sensor. Unlatching of the cam mechanism or such component and the fact that the computer interfaced device is about to be removed from the external computer system is communicated to the external computer system when the sensor component is disengaged from the sensor. A non-maskable interrupt is used to couple the sensor to the controller which is in communications with the external computer system. The sensor component is a magnet, light passage blocker, or mechanical sensor component, and the sensor is a hall-effect sensor, an optical sensor, or a mechanical sensor.

摘要： A system and method for measuring data transmission activity through a port of a switch device interconnecting nodes of a storage area network, the port transmitting data as words of predetermined length, one data word indicating idle port activity. The method includes steps of: counting a number of transmitted words received from the port in a first counter device; and, for each word counted, comparing that word with a predetermined word indicating no (idle) port transmission activity. In response to the comparing, a number of matches are counted in a second counter device. In this manner, a ratio of a number of counted matches with a total amount of words counted indicates available bandwidth for transmitting additional data over that link. Preferably, this value is communicated to a processor device for controlling bandwidth over the link.

摘要： An improved system and method for extending interface communications for a SCSI. The system and method provides SCSI extenders that are able to extend SCSI communications over relatively long distances between at least two SCSI interfaces while also being fast and efficient in operation and inexpensive in implementation. The present system and method reduces latency, buffering, error recovery code, and other such additional hardware and software. SCSI signals are received from one SCSI interface, and the SCSI signals from the one SCSI interface are parallel loaded into a parallel register. The SCSI signals from the one SCSI interface are serialized into serial data, and the serial data from the parallel register is transmitted over an optical communication system. The transmitted serial data is converted back to the SCSI signals that were originally from the one SCSI interface. The SCSI signals that were originally from the one SCSI interface are received by and shifted into a data management and driver system, and the data management and driver system is used to manage and drive the SCSI signals from the one SCSI interface to another SCSI interface. The same system and methodology is applied to extend communications in both directions between the at least two SCSI interfaces. The data management and driver system arbitrates, selects, and drives SCSI signals from one SCSI interface to another SCSI interface. The data management and driver system includes a receive serial shift register and a driver logic device.

摘要： Provided are a method, system, and device for signaling a reconnection inhibitor over a bus to cause the reconnection inhibitor to access the bus to inhibit an Input/Output (I/O) controller from accessing the bus. An initiator transmits I/O requests on the bus to the I/O controller, wherein the I/O requests are queued in an I/O queue, wherein the I/O controller is inhibited by the reconnection inhibitor from draining the queue while the initiator transmits requests to the I/O controller.

摘要： A method and system including apparatus for detecting and blocking an invalid request to a target wherein fiber channels interconnect the data processing configuration. A request made from a hub such as a fabric switch to an internal fiber channel arbitrated loop is blocked by substituting IDLE characters for the frames of data included with the request. The substitution of IDLE signals can also occur within an internal fiber channel arbitrated loop system where access is blocked to a confidential data storage system. If the request is legitimate, the data frames are passed to the target and the requested data is transmitted back to the requester. If the request is refused as being an unauthorized request, the data frames are replaced with IDLE characters and no transfer of confidential data occurs.

摘要： A computer hard disk drive for a use in a redundant array of independent disk drives (RAID) is mounted in a drive carrier for insertion into a drawer in a storage subsystem. The drive carrier has a conventional drive connector on one end for interfacing with the host computer, and an aesthetic bezel on an opposite end. The disk drive has an external optical source and sensor extending from the drive circuit card. The optical source and sensor are located adjacent to the bezel. The bezel is provided with an small optical service interface hole that aligns with the optical source and sensor for accessing them therethrough. The interface hole allows a technician to monitor the drive via the optical source and sensor while the drive is in operation, or to service the drive without removing it from the subsystem drawer.

摘要： A multiplexing system and method for servicing serially linked targets or RAID devices. The multiplexing system couples service interfaces from various targets and devices. The multiplexing system provides a single service link to a single service unit interface. The single service link allows easy access/communications or remote access/communications to an individual target or disk drive within the RAID system. A service unit is directly or remotely coupled to the service unit interface. The multiplexing system has an outgoing multiplexer, an in-going multiplexer, and a multiplexer controller. The service unit communicates with the multiplexing system to select the desired target or disk drive to be serviced. The multiplexer controller detects incoming select target commands and compares incoming target address information with a presently defined multiplexer controller target address information. A switch command is activated or occurs when the incoming select target address information is different with the presently defined multiplexer controller target address information. The multiplexing system accordingly switches to a different target or disk drive to be looked at and serviced when a switch command has been activated or has occurred.

摘要： A serial differential link glitcher system and method which allow for verification of error recovery by an interfaced or linked architecture system. The system and method provide accurate, reliable, and more assured fault simulation, such as noisy interface and dirty link simulations, within an interfaced or linked architecture system for verification of such error recovery and verifies and checks data at a lower level between interfaced devices. The system and method verify disparity errors between interfaced devices and also perform verification of error recovery between electrically linked devices or optically linked devices. At least two devices are coupled together by communication lines. Normal mode allows for normal operation of and normal communication between the at least two devices, and glitch mode provides fault simulation and disparity errors and phase inversion between the at least two devices for testing error recovery of the system. Proper polarity of the communication lines is maintained between the at least two devices when the system is in normal operation mode. The polarity of the communication lines between the at least two devices is switched and inverted when the system is in glitch mode wherein phase inversion and disparity errors in the communication lines are created. The glitcher switch system comprises a switch and a control circuit. The switch allows switching between the communication mode, that is, between the normal operation mode and the glitch mode. The control circuit controls the switch in placing the system in the normal operation mode or the glitch mode.
