Bus Segments on the
Adaptec SCSI Card 29160N
The Adaptec SCSI Card 29160N features Adaptec SpeedFlex™ technol-
ogy. SpeedFlex technology ensures that you get the most performance
from your Ultra160 SCSI devices by electronically isolating the
Ultra160 SCSI segment from the Ultra SCSI segment on the SCSI bus.
With the SpeedFlex advantage, the Adaptec SCSI Card 29160N can
support Ultra160 SCSI devices at speeds up to 160 MBytes/sec while
simultaneously supporting Ultra (legacy) devices at speeds up to 40
MBytes/sec.
If you attach any Wide Ultra or Ultra SCSI devices to the
Ultra160-LVD connector, the data transfer rate for all devices can
run at various speeds. However, if you attach only Ultra160 and
LVD SCSI devices to the Ultra160-LVD connector, all devices will
operate at their maximum possible data transfer rate. That is,
Ultra2 devices will operate at a maximum of 80 MBytes/sec and
Ultra160 devices at a maximum of 160 MBytes/sec.
