Disk drive interfaces have evolved from simple interfaces requiring complex controllers to attach to a computer into high level interfaces that present a consistent interface to a computer system regardless of the internal technology of the hard disk drive. The following table lists some common HDD interfaces in chronological order:
The most familiar Fibre Channel connectors are cable connectors, used for interconnects between initiators and targets (usually disk enclosures). There are also "device connectors" that can be found on Fibre Channel disk-drives and backplanes of enclosures. The device connectors include pins for power and for setting disk options.
A 'universal' cable would have four drive connectors, two for each size of FDD, although cables which have only two drive connectors are common. The cable is normally a ribbon cable. For IBM-compatible floppy controllers, a twist in the cable reverses the order of conductors 10 through 16 for the second connector.
COM port (DE-9 connector). COM (communication port) [ 1 ] [ 2 ] is the original, yet still common, name of the serial port interface on PC-compatible computers . It can refer not only to physical ports, but also to emulated ports, such as ports created by Bluetooth or USB adapters .
SCA-2 connector on Fujitsu MAP3735NC. As time went on, some manufacturers desired connectors even smaller than the SCSI-2 connector. One such in somewhat common use was the VHDCI (Very High Density Cable Interconnect) connector, also known as an "AMP HPCN68M", and sometimes as "SCSI-5". There are 68 pins on the connector in two rows; the pins ...
Rather than focusing on quarterly earnings beats or temporary market sentiment, my investment strategy centers on identifying companies that can compound value over many years or even decades. The ...
3. Plan your withdrawal strategy. Most retirement strategies plan for saving, not spending. So it’s not always easy to remember that there will come a time you have to spend the money you’ve ...
U.2 (pronounced 'u-dot-2' [1]), using the port SFF-8639, is a computer interface standard for connecting solid-state drives (SSDs) to a computer. It covers the physical connector, electrical characteristics, and communication protocols.
