PCI and PCI-X Peripheral Devices SCSI Bus SCSI Device SCSI ID Single-Ended SCSI TolerANT Ultra SCSI Ultra2 SCSI Ultra160 SCSI Ultra320 SCSI VHDCI Peripheral Component Interconnect. A high performance local bus specification that allows connection of devices directly to computer memory. The PCI Local Bus allows transparent upgrades from 32-bit data path at 33 MHz to 64-bit data path at 33 MHz, and from 32-bit data path at 66 MHz to 64-bit data path at 66 MHz. A piece of hardware (such as a video monitor, disk drive, printer, or CD-ROM) used with a computer and under the computer's control. SCSI peripherals are controlled through a SCSI SRCU42X controller (host adapter). A storage adapter (host adapter) and one or more SCSI peripherals connected by cables in a linear configuration. The adapter may exist anywhere on the bus, allowing connection of both internal and external SCSI devices. A system may have more than one SCSI bus by using a multi-channel adapter or by using multiple adapters. Any device that conforms to the SCSI standard and is attached to the SCSI bus by a SCSI cable. This includes SCSI storage adapters (host adapters) and SCSI peripherals. A way to uniquely identify each SCSI device on the SCSI bus. Each SCSI bus has eight available SCSI IDs numbered 0 through 7 (or 0 through 15 for Wide SCSI). The storage adapter (host adapter) usually gets the highest ID (7 or 15) giving it priority to control the bus. A hardware specification for connecting SCSI devices. It references each SCSI signal to a common ground. This is the most common method (as opposed to differential SCSI, which uses a separate ground for each signal). A technology developed and used by Intel to improve data integrity, data transfer rates, and noise immunity through the use of active negation and input signal filtering. A standard for SCSI data transfers. It allows a transfer rate of up to 20 Mbytes/s over an 8-bit SCSI bus and up to 40 Mbytes/s over a 16-bit SCSI bus. A standard for SCSI data transfers. It allows a transfer rate of up to 40 Mbytes/s over an 8-bit SCSI bus, and up to 80 Mbytes/s over a 16-bit SCSI bus. A standard for SCSI data transfers. It allows a transfer rate of up to 160 Mbytes/s over a 16bit SCSI bus. A standard for SCSI data transfers. It allows a transfer rate of up to 320 Mbytes/s over a 16bit SCSI bus. Very High-Density Cable Interconnect. This cable is used to connect external connectors to your storage adapter. 29
