Ultra2 SCSI
Data transfers 40 megabytes per second, first
defined in SPI-2, below defines how it is used in the different generations of the SCSI
standards.
SCSI SPI-2 (SCSI Parallel Interface)
8 bit SCSI asynchronous commands with Synchronous
data transfer rates up to 40 megabytes per second. LVD (Low Voltage Differential) and
Differential (HVD – High Voltage differential) bus transceivers based on EIA 485
allowed in SCSI SPI-2.
Note: Currently all the implementations have been
LVD SCSI, wide. The HVD transceivers are not available for Fast-40 speeds.
