Bus Doctor™ RX-252 Analyzer Begins Shipping

New Bus Doctor Family Member provides Testing Platform for Wide Port Serial Attached SCSI (SAS) and PCI Express

Storage World Conference, Long Beach, CA. (June 30, 2004) -- Data Transit Corporation, the leading supplier of modular bus protocol analyzers, today announces that it has begun shipping the RX-252 Analyzer, the newest member of the Bus Doctor™ Analyzer family. The new Analyzer is a groundbreaking product with performance and capabilities that redefine the high-end of the bus analyzer market. Designed specifically for high speed, multi-lane, multiple protocol serial buses, it provides the analysis and test tool engineers need to design and manufacture products for PCI Express* x16 architecture and Wide Port Serial Attached SCSI (SAS).

The new Analyzer supports 252 memory channels permitting it to keep up with the greater data throughput of bus types like Wide Port SAS; the possibility of lost or dropped packets is completely eliminated. An onboard processor speeds up trace analysis functions such as filtering and histogram creation. Up to 9.2 Gigabytes of physical buffer memory reside on the BUFF version of the RX-252 providing one of the deepest memory buffers available on any analyzer.

"Today, PCI Express technology is being adopted as a general purpose I/O by the industry," said Tony Pierce, PCI-SIG chairman. "PCI-SIG appreciates Data Transit's contribution to accelerate that adoption by providing manufacturers with analysis tools based on PCI Express technology."

The RX-252 may be combined or stacked with other RX-252s Analyzers or with the 36/108 channel RX Analyzers. Stacking multiple analyzers or multi-analysis is a unique feature of Data Transit's analyzer products. Stacked RX Analyzers share a common reference clock. In addition, there is support for cross-sequence triggering. This functionality allows triggers to span across multiple Bus Doctor RX Analyzers. The RX-252 is equipped with 5 hardware triggers; 3 trigger inputs and 2 trigger outputs.

The signature Bus Doctor Software environment, with its familiar Command, State and Histogram listings, has been significantly enhanced to support multi-lane data found in Wide Port SAS and PCI Express architecture. A new Tree Listing provides for viewing a high-level summary of a multi-packet sequence using the familiar tree-view which allows for expanding or collapsing the detail in command sequences. It retains the ease of use that has long been a hallmark of Bus Doctor Software.

The RX-252 is completely portable. Pods are designed to dock and lock with the analyzer to form a single instrument. A handle on the back side of the Analyzer permits for easy transport.

"Storage, motherboard and graphics developers and manufacturers working with PCI Express and SAS technologies are the customers that will benefit most from the Bus Doctor RX-252 Analyzer" said Dale Smith, Founder, President and CTO of Data Transit. "We are pleased to be able to expand our modular philosophy with such a highly functional product for multi-lane buses."

Data Transit showcases the Bus Doctor RX-252 Analyzer at the Hands On Storage Clinic at the Storage World Conference at the Convention Center in Long Beach, California from June 29th to July 1st.

Since the RX-252 was announced earlier this year, interest in the product has been high and Data Transit has taken in unprecedented numbers of orders. To purchase a Bus Doctor Analyzer or to arraign for a demonstration, please contact Data Transit or one of its worldwide distribution partners.
