The ATTO ExpressPCI UL5D Low-Profile SCSI 
host adapter is the industry’s first true low-profile 
PCIe SCSI host adapter, and is the perfect 

 

 

 

 

 

complement to ATTO’s existing high-performance 
SCSI host adapter line. The UL5D LP offers users 
the same high-performance and feature set that 
ExpressPCI SCSI host adapters are renowned for, 
but due to the low-profile form factor of the UL5D 
LP, it is also ideal for integration into enclosures 
where space is at a premium, such as 1U/2U 
server chassis. The UL5D LP offers external dual-
stacked VHDCI SCSI connectors, allowing direct-
attached applications to realize data-transfer rates 
of up to 640 MB/sec. 
 
Additionally, the ExpressPCI UL5D LP offers 

 

 

 

 

 

support for the next generation of PCI bus 

 

 

 

 

 

 

technology with a 4-lane PCI Express (PCIe)
interconnect. By leveraging the high-performance 
of both PCI Express and Ultra320 SCSI, the UL5D 
LP is an ideal fit for data-intensive environments, 
including video-editing applications requiring 

 

 

 

support for multiple streams of 10-bit high-
definition video. The combination of high-
performance and a low-profile form factor provides 
an ideal solution for space constrained enterprise 
servers, as well as high-end workstations running 
high-volume, mission critical applications such as 
messaging and databases. 
 
ATTO  host  adapters  offer  ATTO’s  exclusive      
Advanced Data Streaming (ADS

TM

) technology, 

and the ExpressPCI UL5D LP is no exception. 
ADS manages latency and allows for fast and   
efficient data movement, reducing CPU utilization.  
 
With  features  including  Ultra320  SCSI,  PCI       
Express technology, the industry’s first true low-
profile form factor dual channel design, and ATTO-
exclusive 

technologies 

such 

as 

ADS, 

the           

ExpressPCI UL5D LP is perfect for providing high-
performance Ultra320 SCSI to space-constrained 
chassis and enclosures.

ExpressPCI UL5D Low-Profile 

• Maximize data throughput 

with dual channel connectivity 
aggregating performance 
across multiple SCSI ports 

• Leveraging the latest in SCSI 

storage connectivity, the 
UL5D low profile delivers up 
to 640 MB/sec. data through-
put, making it twice as fast as 
Ultra160 SCSI. 

 

• Maintain accessibility to mis-

sion-critical data by transpar-
ently redirecting data requests 
through alternate channels. 

• Alleviate data transfer bottle-

necks and move data more 
efficiently while managing 
latency with ATTO’s exclusive 
ADS™ technology. 

 
One Click Installation 

• Save time with factory preset 

configuration for plug and play 
operation. 

• Simplify installation, manage-

ment and monitoring with a 
multi-platform Configuration 
Utility featuring an intuitive 
GUI.
