Abstract
An Inifiniband (IB) network that incorporates a Fibre Channel (FC) network is disclosed. The IB and FC networks are coupled by a gateway that maps the FC network to a virtual IB network. In generating the virtual IB network, the gateway may provide a virtual IB target for each node port in the FC network, and may further provide a minimum number of virtual IB switches necessary to support the virtual IB targets. The gateway assigns a globally unique identifier (GUID) to each of the virtual IB targets, and may further associate local identifiers (LID) with the virtual IB targets. The gateway preferably emulates subnet management agents (SMA) and general service agents (GSA) of the virtual IB targets when management IB packets are received, and the gateway preferably converts non-management IB packets directed to the virtual IB targets into FC frames directed to the corresponding target FC devices.
