Combined fibre channel and sas host bus adapter

Abstract

Apparatus, systems, and methods for coupling Fibre Channel (FC) storage devices and serial attached SCSI (SAS) storage device to a computer system through a single host bus adapter (HBA). The HBA includes a SAS storage controller four coupling to one or more SAS storage devices and an FC interface for coupling to one or more FC storage devices. The HBA also includes translation logic to translate information exchanged between the SAS storage controller and the FC storage device(s). Translation may include translation of addressing information between FC protocols and formats used by the SAS storage controller, may include use of a buffer to enable exchanges at different data rates, and may include use of a buffer to aggregate an inbound FC multiframe sequence into a single data buffer for use by the SAS storage controller.
