ATTO SCSI HBAs
ATTO ExpressPCI UL4S
Single-channel Ultra320 SCSI Host Adapter
Featuring PCI-X Support and Vpath™ Technology
The UL4S single-channel Ultra320
adapter is the latest generation of
the ATTO ExpressPCI family of highperformance SCSI host adapters for
data-intensive environments. Data
transfer rates of up to 320 MB/sec., coupled
with ATTO Vpath™ Technology and support
for the advanced PCI-X bus, make the
UL4S the ideal single channel SCSI
connectivity solution for Enterprise servers
and high-end workstations running
high-volume, mission-critical applications
such as messaging and databases.
ATTO’s exclusive Vpath technology
offers users the flexibility of connecting
high-speed Ultra320 devices externally
and slower legacy devices internally,
or vice versa, without sacrificing the
performance of the high-speed device.
