Abstract
A verification mechanism monitors incoming and outgoing traffic between a channel adapter and a switch fabric in an InfiniBandSM system in order to verify that the InfiniBandSM protocol is correctly followed by the channel adapter. The verification mechanism uses a simple hardware-independent interface to query the channel adapter hardware for specific values and completion queue, queue pair and work queue element attributes that are required for verification. The verification mechanism creates a plurality of verification components that monitor incoming and outgoing messages and verify that each of the channel adapter elements correctly follows the protocol. The verification mechanism is controlled by a verification application programming interface (API) that allows different test benches and tests to incorporate InfiniBandSM protocol verification in any test system for use with any hardware.
