Implementations are disclosed that provide protocols for connecting an intelligent service module within a storage area network (SAN). The protocols support physical connections between the intelligent service module and a director-level switch of the SAN. In some variations, the intelligent service module may comprise a director service module (DSM), a domain-sharing leaf switch service module (LSSM), or a non-domain-sharing LSSM. The protocols provide for establishing link parameters and negotiating responsibilities between the intelligent service module and the director-level switch. In one configuration, for example, ELP and ELP_ACCEPT frames may be used to establish the link parameters. In another configuration, ESC and ESC_ACCEPT frames may be used to negotiate responsibilities between the intelligent service module and the director-level switch. Other configurations also provide an ownership status of the intelligent service module that is used to determine whether the switch can initiate management of the intelligent service module.
