SerialTek architected the BusXpert to solve problems familiar to many SAS and SATA developers and integrators:
How to capture massive amounts of data and display it quickly.
How to be sure the data captured is accurate.
Once the data is captured, how to quickly search for areas of interest.
BusXpert's software was designed from the ground up to fully utilize the fast pipes and large buffers. Existing methods of dealing with the upload and display of trace data were not efficient enough and lead to some key innovations found only in the BusXpert software: Pre-indexing, Trace-processing, Trace-formatting, and Compression.
Pre-indexing enables fast displaying of, searching for, and hiding of the captured bus activity. Trace-processing works with pre-indexing to allow for quicker display of transactions, lowers the time needed for searching and allows saved traces to perform just as fast as traces stored on the BusXpert. Trace formatting enables efficient use of the host system’s disk space, allowing more traces to be saved without the extra data found in other trace formats. Compression is used to cut down on the space needed for repetitive SAS and SATA link layer traffic and also utilize the pipe connection to the host system more effectively.
BusXpert provides a variety of traffic displays for analysis of the bus at different protocol layers, each optimized with the innovations mentioned above.
