bus segment. Without SpeedFlex tech-
nology, any Fast or Ultra SCSI peripheral 
connected to an Ultra2 SCSI bus will
drop the maximum burst rates of all
peripherals on the bus to the Ultra
SCSI performance level.

Maximum Configuration Flexibility
The SCSI Card 2940U2W offers maxi-
mum configuration flexibility by
quadrupling the allowable length of the
SCSI bus to a maximum of 12 meters.
This feature is particularly useful when
configuring external storage and clus-
tered servers. In addition, the SCSI Card
2940U2W provides four connectors,
which can all be used simultaneously,
and four SCSI cables. The cables enclosed
with the kit include a terminated Ultra2
cable and an internal-to-external 50-pin
cable, which improve ease of installation
and enable a wide variety of system
configuration options.

Highest Quality, Maximum Compatibility
The latest in a long line of PCI-to-SCSI
cards from Adaptec

®

, the SCSI Card

2940U2W has been thoroughly tested
with over 350 systems and peripherals
to deliver the utmost in reliability and
compatibility. As the industry leading
manufacturer of SCSI cards, Adaptec
assures the widest possible compatibility,
now and in the future.

As the power of applications, processors,
and storage devices increase, high-end
computer users are seeking ways to
optimize their system performance. The
SCSI Card 2940U2W provides the
throughput speed, flexibility, and com-
patibility required to optimize today’s
workstations and PC servers. It provides
Ultra2 SCSI data transfer rates up to 80
MByte/sec and optimizes the perfor-
mance of all peripherals attached to the
card with SpeedFlex technology. By
providing 4 connectors and extended
cable lengths, the SCSI Card 2940U2W
also allows for maximum system con-
figuration flexibility.

Maximum Performance
The SCSI Card 2940U2W can burst
data up to 80 MByte/sec on the Ultra2
SCSI bus, which doubles the maximum
burst rate of Wide Ultra SCSI. This
Ultra2 SCSI transfer rate translates
into increased performance of data
intensive applications.

Assured Ultra2 Performance With
SpeedFlex Technology
The SCSI Card 2940U2W features
SpeedFlex technology which ensures
the most performance from Ultra2
peripherals by creating two electroni-
cally isolated SCSI bus segments on the
card—an Ultra2 segment and an Ultra
SCSI segment. These two segments
enable the SCSI Card 2940U2W to
simultaneously operate at both Ultra2
SCSI and Ultra SCSI speeds. With
SpeedFlex, the board can support
Ultra2 peripherals at speeds up to 80
MByte/sec on the Ultra2 SCSI bus seg-
ment, while simultaneously supporting
Fast and Ultra SCSI devices at speeds
up to 40 MByte/sec on the Ultra SCSI
