Nexsus load balancing mechanism for FcoE Mappings

Posted on by Admin

On the Nexus 5000, the default load balancing mechanism on the LACP port-channel is source-destination. If we leave it in this state, all the FCoE traffic will take the same link in the port channel when the Nexus 5000 is forwarding frames to the upstream device. To enable the Nexus 5000 to load balance using exchange IDs, we configure it for ‘source-dest-port’ load balancing. Nexus5000(config)# port-channel load-balance ethernet ? destination-ip    Destination IP address destination-mac   Destination…

Posted on by Admin

Original Link# http://www.stephenwagner.com/?p=765 Earlier today I was doing some work in my demonstration vSphere environment, when I had to modify some settings of one of my VMs that are setup as the latest version (which means you can only edit the settings inside of the vSphere Web Client). To my surprise, when logging in, immediately I received an error: “ManagedObjectReference: type = Datastore, value = datastore-XXXX, serverGuid = XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX refers to a managed object that…
