Abstract: Provided are techniques for the efficient distribution of peer zone databases in a FC Fabric. In an example, a switch instantiates a peer zone definition defining a peer zone in which two or more initiator host devices are each permitted to communicate with one or more target storage devices via the switched FC fabric and the two or more initiator host devices are prevented from communicating with each other. The switch stores the peer zone definition in a peer zone database at the FC switch, and distributes the peer zone definition to other FC switches of the switched FC fabric without performing a Fabric lock operation.

Abstract: Presented herein are priority route based techniques for mitigation of slow drain devices in a Fibre Channel (FC) fabric comprising a plurality of FC switches. In accordance with examples presented herein, a first FC switch in a FC fabric receives an indication that a first computing device attached to the FC fabric has entered a slow drain condition. The first FC switch is configured to prepare and install a priority route for packet flows directed to the first computing device.
