Abstract
A method for improving performance of a host bus adapter in a data storage system is disclosed. In one embodiment, such a method uses, as an interface to a memory controller contained within a host bus adapter, multiple two-way ports configured to operate in parallel. The method uses, within each two-way port, a read FIFO buffer for transferring read data across the two-way port and a write FIFO buffer for transferring write data across the two-way port. The method also uses the read FIFO buffer and the write FIFO buffer within each two-way port to provide speed-matching for different clock speeds that operate on opposite sides of the two-way port. A corresponding system and computer program product are also disclosed.
