			VLANs are used across the storage network to facilitate the overlay of multiple logical networks on to a single physical infrastructure. For the most part, they are used to extend the Rocks MPI and Management networks across the street, while not interfering with the primary NFS network.

			Generally, the following tags are used:


			{\| border="1" cellspacing="0" cellpadding="5"
			! VLAN Tag \|\| Name \|\| Description

			\| 1 \|\| NIC Storage \|\| NFS Private network, as described above.<BR>Untagged on core switches.
