Apparatus, systems, methods, and articles may operate to restrict an order of processing of frames associated with a task context stored in at least one context cache memory location. The order of processing may be restricted by selectively locking the context for exclusive use by a selected lane in a multi-lane serial-attached small computer system interface (SAS) hardware protocol engine while the selected lane processes a selected one of the frames.
