Abstract
Accessing some storage-area networks (SANs) requires a client computer to include a special electronic component, known as a host bus adapter (HBA). However, the present inventor recognized that conventional host bus adapters add considerable expense to the cost of accessing the storage-area network. Accordingly, the present inventor devised a host bus adapter that is implemented in software and thus referred to as a 'virtual' host bus adapter. One exemplary embodiment of the virtual host bus adapter includes a hardware-emulation module that makes the virtual host bus adapter appear to operating system environments as a conventional host bust adapter with dedicated hardware.
