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.

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.

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 disk drive library has individual disk drives that are each provided with a combination mechanical and electrical connector for interfacing with a library backplane. Each connector has two components. The first component is mounted to the drive and has an electrical contact with a metallic burnished core of highly conductive material that is surrounded by an annular magnet. The mating component is on the backplane and is similarly formed with the opposite pole of a second magnet. When the two components are brought into close proximity, the two contacts attract each other to mate the contact cores, and thus establish an electrical connection. This connection is augmented by a spring mechanism to provide a solid, reliable connection.

A self-healing coupler for a serially linked device that is serially coupled to other devices. The serially linked device has a communication input and a communication output. When a break occurs between a first serially linked device and other devices, as indicated by a lack of communication output from the first serially linked device, the self-healing coupler by-passes the break in the first serially linked device to maintain communication between the other devices. The invention is particularly suited to maintaining communication to serial Redundant Array of Inexpensive Disks (RAID) storage devices.

One embodiment of a picking tool for an automated library of disk drives has an electromagnet, a tapered hole, and a ventilation system. The ventilation system has a box fan with an impeller for moving air through ducting located within the picking tool. The ducting includes a vents located adjacent to one surface of the picking tool. The picking tool is designed to work in conjunction with a disk drive carrier having a front bezel equipped with a tapered guide pin that is complementary to the tapered hole, and vent ports. The guide pin provides alignment between the carrier and the picking tool. The automated disk drive library has a rack with drawers for containing the carriers. The picking tool is mounted to a robotic arm for selectively engaging and interfacing with the carriers. After the picking tool aligns with a desired carrier, the picking tool moves toward the carrier to insert the guide pin into the tapered hole. The disk drive is ventilated by activating the ventilation system to force air through the ducting and vents to cool the disk drive via the vent ports.

An AC power interruption detection system is provided which compares an AC signal with a phased AC reference signal to determine the presence or absence of an AC power signal. By comparing the AC power signal with a phased reference signal, power interruption detection occurs within a predetermined minimum time frame, for example, with  cycle. In exemplary embodiments, the detection system includes AC power signal frequency multiplying circuitry to improve speed and performance. In other exemplary embodiments, the detection system includes threshold detection circuitry to detect undervoltage (e. g. , brownout) and/or overvoltage (e. g. , spike) conditions of the AC power. In system-level embodiments, the interruption detection system is implemented in a switch array environment in which a switch controller controls a redundant switch array based on the detection signal generated by the power interruption detection system to couple a selected AC power line, from one or more redundant AC power lines available, to a load.
