What is the current bast practise when it comes to ISCSI and layer 3? We’re building a SAN between the buildings in our campus to allow replication between some SANs.
My thought process is to have a vlan and subnet in each facility and distribute the routes via OSPF. We have Nexus 9k and Nexus 5k switches to do this on. Each facility will have a SAN and server(s) in the same subnet that access the SAN, and the SAN with replicate to a SAN in a different building/subnet. The subnets will belong to VRFs on the switches so we can trunk LAN and SAN to the servers (mainly ESX).
Does anybody have any experience with this sort of setup for ISCSI. I really don’t want to stretch layer 2 between buildings.
