Abstract
A method and system for emulating a hardware Internet Small Computer System Interface (iSCSI) Host Bus Adapter (HBA) without risking an interruption of communication between a computer and a remote secondary storage device is presented. During normal operations, a (hardware emulating) software iSCSI HBA drives a Network Interface Card (NIC) to afford communication between the computer and the remote secondary storage. If an operating system (OS) anomaly occurs in the computer, the NIC is normally disconnected by the OS. To maintain communication between the computer and the secondary storage device if such an event occurs, a failover network device is called up by the computer's System Management Memory (SMM) Basic Input Output System (BIOS), which allows uninterrupted communication to continue between the computer and remote secondary storage device.
