U3051B BusXpert Micro Series SAS/SATA Analyzers

Data Sheets

High Performance Hardware Platform

For today’s SAS and SATA developers and integrators, getting to the root of a problem can be especially difficult when there isn’t an obvious trigger condition. Troubleshooting is further complicated by ever-climbing storage capacities, data rates, and protocol complexity. Integrators and developers need faster and deeper analyzers to keep up. Traditionally, those needing to capture large amounts of traffic have been faced with limited trace buffers, long waits to view the data, slow searches, and slow saving. SerialTek has overcome the old limitations with the BusXpert Series of SAS/SATA Analyzers. The BusXpert uses advanced technologies such as the industry’s first PCI Express x4 uplink to the host (550 MB/s), up to 18 GB of buffer, Hardware Accelerated Gigabit Ethernet, pre-indexed and compressed trace data, multiple analysis processors, and instant display of the captured data. The BusXpert also features easy to use trigger­ing, pre/post-filtering, textual search and sequence search, and many different displays of the captured traffic. It’s available in a variety of configurations to fit specific needs for buffer size, port-count, protocols, and budget. The BusXpert breaks free of past analyzer limitations and lets users spend more time on development and debug efforts. SerialTek delivers on it’s promise of “Analysis Without the Limitations.”

Traffic Display

The BusXpert provides a variety of traffic displays, with some optimized for different protocol layers, some optimized for time relationships, some correlate directly with the SAS/SATA specification, and some provide just the user data. All of the views are exportable via CSV and XML. Additionally, some can be exported to HTML. Bookmarks make it easy to label and discuss specific events in the trace.

Searching for Data

Easily search for specific frames, primitives, addresses or other events with the Quick Search and Advanced Search functions enhanced with InstaSearch technology

Pre-Filtering

Filtering out specific primitives, frames, data, and addresses is a snap. Easily specify which patterns to filter out during a capture to maximize buffer space, resulting in more meaningful data.

Triggering

BusXpert’s triggering interface allows for quick definition of events with frame layouts matching the SAS2 and SATA specifications. Simple and complex triggers can be built with ease. BusXpert Micro’s advanced triggering includes:

  • Up to 3 sequencers
  • Up to 16 states per sequencer
  • Up to 32 counters and timers
  • Multi-level branching
  • User defined events
  • External Trigger In/Out

BusXpert MicroLite can trigger on single events only. Also featured is the ability to copy and paste frames and primitives from an open trace, saving additional time on defining events. Any of the events created can be saved off to the User Events folder for future use.

Line Status

The Status menu shows a visual repre­sentation of what is currently occurring on the bus and also a status of the capture. The Spd/OOB/Link/Frame/10b Err/Cmd/and Err Sts LEDs match the activity on the front of the BusXpert. Status lights such as Frame, Cmd, Link, and OOB are useful in determining what is happening on the bus at any given time, while the error lights such as 10b Err and Err Sts let the user know that signal errors and command errors are occurring.

Real-Time Statistics

Simultaneously measure individual read and write, and IOPs performance statistics while the analyzer is recording bus traffic. Compare performance across all of the links to see performance differences. Use live counters to keep track user-definable events such as frame error rate counting, and average IOPs.

Post-Capture Statistics

After capturing a trace, the BusXpert provides a variety of statistical measurements. View statistics such as command performance (latency, throughput, etc), link utilization (frame turn-around rate, etc), SMP and connection management, and many more. Click on data within each report to go to the event in the trace. All of the reports are exportable to HTML, XML, and XLS formats for external datamining and reports.

System Requirements

To get the best performance out of your BusXpert Analyzer, we recommend the following systems:

  • Minimum configuration: 1.5 GHz Celeron or AMD equivalent processor, 1 GB of Memory, Gigabit Ethernet and/or USB, Graphics capable of supporting 1024x768
  • Recommended Configuration: 2.8 GHz or greater processor, 3 GB or greater of 1.3 GHz FSB memory, PCIe x4 or ExpressCard slot, Graphics capable of supporting 1920x1200 or greater
