Abstract
The present invention relates to a general purpose interface to a Fibre Channel array controller, more particularly to a gigabit interface converter (GBIC) or a gigabit link module (GLM) channel adapter, and to the use of a channel controller with associated general GBIC/GLM adapters to provide an ultra-high bandwidth bus. Specifically, the present invention provides an array controller. The array controller through programmable functionality causes a plurality of devices to appear as a single device. Moreover, the array controller provides a plurality of general purpose interfaces to allow connection of a plurality of heterogeneous devices. Thus, the present invention may allow an integrated storage system comprising disk drives, tape-units, CD-ROMs, optical drives, and/or the like. Alternatively, the array controller may be programmed to implement bus protocols. Thereby, the array controller may provide an ultra-high bandwidth bus by utilizing Fibre Channel connections and optical interfaces for connected devices.
