Two links in Active/Passive across two switches is exactly how I do it. I also ensure that nothing but DRBD uses those interfaces. I also do the same for a dedicated cluster communication network. https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial#Network There are other benefits to switches; Bandwidth monitoring, cable diagnostics, etc. Now with all this said; I think I will try to squeeze some time to run some benchmarks with and without switches when I return to my lab. I'd much rather have numbers to back positions in debates like this. :) -- Digimer Papers and Projects: https://alteeve.com _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
