Abstract
A method and system for transferring data between a host and a Serial Attached Small Computer Interface ('SAS') device using a storage controller is provided. The storage controller includes, a World Wide Name ('WWN') module that includes a table having plural entries, wherein each row includes a WWN address, an initiator tag value field, an input/output counter value that tracks plural commands for a connection. A WWN index value represents the address of a row having plural entries. The method includes, comparing frame elements of incoming frames, including a unique WWN address with the WWN module entries; and if there is a match, updating a counter value for a connection between the storage controller and a device sending frames. The counter value is increased when a command frame is received and decreased when a command is executed and a response is sent to the device.
