The UL4S single-channel Ultra320 host adapter is 
the perfect compliment to ATTO’s ExpressPCI fam-
ily of high-performance SCSI host adapters for 
data-intensive environments. Boasting a data-
transfer rate of up to 320 MB/sec. and offering  
support for PCI-X busses, the UL4S is an ideal fit 
for Enterprise servers and high-end workstations 
running high-volume, mission-critical applications 
such as messaging and databases.  
 
ATTO’s exclusive Vpath

TM

 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.  In essence, 
with Vpath

TM

, the UL4S functions similar to a dual  

channel card by allowing data to be read through 
port 

one 

and 

written 

through 

port 

two                 

simultaneously, thus improving overall productivity. 
 
Installation of the ExpressPCI UL4S host adapter is 
a breeze. Thanks to factory-preset configurations, 
the UL4S is ready out-of-the-box for plug and play 
operation. The included Configuration  Utility      
featuring an easy-to-use GUI simplifies the effort 
associated with installation, management and 
monitoring of the host adapter. 
 
The ExpressPCI UL4S is the first choice for users 
working in environments with demanding server 
and professional workstation environments. By 

 

offering support for Ultra320 SCSI and PCI-X, in 
addition to ATTO-designed performance-enhancing 
technologies including Vpath the ExpressPCI UL4S 
offers both the performance and feature set
