A version of the SCSI command specification.
SCSI-2 shares the original SCSI’s asynchronous and synchronous modes and adds a “Fast SCSI” mode (Wide SCSI” (16 bit, Another major enhancement was the definition of command sets for different device classes. SCSI-1 was rather minimalistic in this respect which led to various incompatibilities especially for devices other than hard-disks. SCSI-2 addresses that problem. allowing scanners, hard disk drives, CD-ROM drives, tapes and many other devices to be connected.
Normal SCSI-2 equipment (not wide or differential) can be connected to a SCSI-1 bus and vice versa.
hardware An ongoing standardisation effort to extend the capabilities of SCSI-2. SCSI-3’s goals are more devices on a bus (up to 32); faster data transfer; greater distances between devices (longer cables); more device classes and command sets; structured documentation; and a structured protocol model. In SCSI-2, data transmission is parallel (8, 16 or 32 bit […]
- Scsi adaptor
hardware (Or “host adaptor”) A device that communicates between a computer and its SCSI peripherals. The SCSI adaptor is usually assigned SCSI ID 7. It is often a separate card that is connected to the computer’s bus (e.g. PCI, ISA, PCMCIA) though increasinly, SCSI adaptors are built in to the motherboard. Apart from being cheaper, […]
- Scsi controller
- Scsi id
hardware The unique address of a SCSI device. SCSI IDs range from 0 to 7 for 8-bit SCSI systems, 0 to 15 for 16-bit and 0 to 31 for 32-bit systems. The SCSI adaptor is usually assigned ID 7. A device’s SCSI ID is often set by switches on the device. (1999-09-01)
