ExpressPCI UL4D

Host Adapter

Dual-channel Ultra320

SCSI Host Adapter

With PCI-X Support

The UL4D dual-channel Ultra320 host adapter is

the perfect complement to ATTO’s ExpressPCI

family of high-performance SCSI host adapters for

data-intensive environments. Boasting data-

transfer rates of up to 640 MB/sec. and offering

support for advanced PCI-X busses, the UL4D is

an ideal fit for Enterprise servers and high-end

workstations running high-volume, mission-critical

applications such as messaging and databases.

ATTO host adapters offer ATTO’s exclusive

Advanced Data Streaming (ADSTM) technology,

and the ExpressPCI UL4D is no exception. By

effectively managing latency and allowing for fast

and efficient data movement, utilization of the CPU

is reduced, freeing it up to perform other mission

critical tasks.

Installation of the ExpressPCI UL4D host adapter is

a fast and easy. Thanks to ATTO’s factory-preset

configurations, the UL4D 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 UL4D 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 ADS, the ExpressPCI UL4D

offers both the performance and feature set neces-

sary for today’s data-intensive applications.

Technical Highlights
