Free sastracer driver

SASTracer analyzer is a Serial Attached SCSI test and debug platform that combines non-intrusive, recording with powerful decoding features that interpret and explain SAS protocol. Built on the CATC Protocol Analyzer System 10K Platform, the SASTracer is the first SAS analyzer to support 4-Wide links running at 1.5 or 3.0Gbps.

The SASTracer does more than just record traffic moving across 4-Wide links. It provides a time-synchronized view, both at the DWORD and the Frame level for all four links. Plus it logically groups all frames that are part of a common operation - even if they are spread across multiple physical pathways. This eliminates the need to decode SAS transactions manually and helps you find problems faster.
