I’ve seen often many users asking in forums how to properly configure a network in order to deploy a iSCSI storage, especially in really small environments.
So, I created this post in order to explain how I usually configure a system with an HP StorageWorks P2000 G3 iSCSI storage and a small cluster with 3 vSphere servers. If you are using a different storage, you would probably have to change some configuration, but the principles are always the same.
