Abstract
A method and system are provided for determining maximum data throughput between a host adapter and one or more target devices coupled to the host adapter through a bus. A first set of device identifying data is obtained from a target device over the bus. Then, a maximum data throughput rate is negotiated between the host adapter and the target device over the bus. Next, a second set of device identifying data is obtained from the target device over the bus at the negotiated maximum data throughput rate. Read and write tests are performed to determine the maximum data throughput rate. When the first and second sets of device identifying data are identical, the host adapter and the target device are operated over the bus at the negotiated maximum data throughput rate.
