Dynamic Login Distribution performs auto-failover for the server logins if the corresponding uplink port becomes unavailable. Servers that were logged in to the failed port are reconnected to one of the remaining ports in the VC SAN fabric. This configuration offers increase performance and better availability. The server-to-uplink ratio is adjustable, up to 2:1 with the VC-FC 8Gb 24-port module (as few as two servers share one physical Fabric uplink) and up to 4:1 with the VC-FC 20-port and FlexFabric modules. Considerations The SAN switch ports connecting to the VC-FC modules must be configured to accept NPIV logins. Due to the use of NPIV, special features that are available in standard FC switches like ISL Trunking, QoS, extended distances, etc. are not supported with VC-FC and VC FlexFabric.
