An ANSI standard bus design. SCSI host adapters are used to adapt an ISA, EISA, MCI, PCI, or VLB (VESA Local Bus) bus to a SCSI bus so that SCSI devices (such as disk drives, CD-ROMs, tape backups, and other devices) can be interfaced. A SCSI bus accommodates up to eight devices, however, the bus adapter is considered one device, thereby enabling seven usable devices to be interfaced to each SCSI adapter. SCSI devices are intelligent devices. SCSI disk drives have embedded controllers and interface to a SCSI bus adapter. A SCSI interface card is therefore a "bus adapter", not a "controller". |
