Formally called buffer-to-buffer credit (BBC) spoofing, and also called buffer-to-buffer credits, this is a technology that effectively removes limitations on data throughput for long-distance transmissions in a Fibre Channel storage area network (SAN). Usually Fibre Channel protocolslimit the distance between the source and the destination network to within a few kilometers. Using buffer-to-buffer credits makes it possible to use off-site storage hundreds of kilometers away.
