Creating a virtualized environment by using storage virtual machines (SVMs) and LIFs enables you to expand your SAN environment to all of the nodes in your cluster.
You can log in to any node in the SVM to administer all of the nodes in a cluster.
With MPIO and ALUA, you have access to your data through any active iSCSI or FC LIFs for the SVM.
If you use SLM and portsets, you can limit which LIFs an initiator can use to access LUNs.
