ExpressPCI UL4S

Single-channel Ultra320

SCSI Host Adapter

Featuring PCI-X Support and

Vpath

The UL4S single-channel Ultra320 host adapter is the perfect compliment to ATTO’s ExpressPCI family of high-performance SCSI host adapters for data-intensive environments. Boasting a datatransfer 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 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 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 includin g Vpath the ExpressPCI UL4S offers both the performance and feature set necessary for today’s data-intensive applications.
