Single-Ended
SCSI 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).
SureLINK The domain validation method developed and used by LSI Logic.
SureLINK Domain Validation provides three levels of integrity checking:
Basic (level 1), Enhanced (level 2), and Margined (level 3).
Synchronous
Data Transfer One of the ways data is transferred over the SCSI bus. Transfers are
clocked with fixed frequency pulses. This is faster than asynchronous
data transfer. Synchronous data transfers are negotiated between the
SCSI host adapter and each SCSI device.
TolerANT A technology developed and used by LSI Logic to improve data integrity,
data transfer rates, and noise immunity, through the use of active
negation and input signal filtering.
Ultra SCSI 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. The STA supports using the term “Ultra SCSI” over the older
term “Fast-20”.
Ultra2 SCSI 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. The SCSI Trade Association (STA) supports using the term
“Ultra2 SCSI” over the term “Fast-40”.
Ultra160 SCSI A standard for SCSI data transfers. It allows a transfer rate of up to
160 Mbytes/s over a 16-bit SCSI bus.
