US 6,687,856 B2 · Method and apparatus for recreating fiber channel traffic

Abstract

A logic analyzer or a bus analyzer may be used to capture data from a source computer system to diagnose a problem arising in the source computer system. In many cases the problem can be traced to a particular hardware/software subsystem. Quite often, a customer of the manufacturer of the hardware/software subsystem maintains the source computer system. In the manufacturer's facilities is a reference system operated by a technician or engineer responsible to test and support the hardware/software subsystem. The source computer system and the reference system thus may involve different hardware and software configurations and possibly even different operating systems. The present invention provides a system and a method to allow data captured in a source computer system to be replayed in the remote reference system so as to recreate a captured event or analyze performance.

Dependent claims

A method of electronic system analysis comprising the steps of:

capturing data that adheres to a captured protocol layer level, said captured data being stored in a captured data file;
converting said a captured data file from said captured protocol layer level to a designated protocol layer level and storing said captured data that adheres to said designated protocol layer level as One template data structure in to a set of template data structures, wherein the captured data file includes data captured from a transmission through an interconnect between a source host computer and a source target device in a source computer system;
and
playing back at least a subset of the template data structures to reproduce an event, by using template data structures to reenact the transmission.
