Abstract

Hot-plug actions are enabled in an M-host, N-card system architecture. An arbiter receives status signals from the N hot-pluggable cards, and transfers the status signals to at least some of the M host devices. In response to the status signals indicating a hot-plug action, the arbiter receives at least one host command. The arbiter transfers the host command to one or more of the N hot-pluggable cards according to an arbiter algorithm.
