Access "Virtual SANs bring order to chaos"

Published: 16 Oct 2012

Cisco has embedded virtual storage area network (VSAN) technology in its new Multilayer Director and Fabric Switch (MDS) line. This new technology will let you construct fabrics as collections of ports--not collections of switches. You can also segregate not only just traffic, but fabric services, between the virtual SANs. Integrating VSANs into your fabric An MDS switch can act exactly like a non-VSAN switch by using a single VSAN and using only E ports and ISLs to communicate with other switches. This single VSAN and its fabric would communicate with all the non-VSAN switches in exactly the same way they do and participate fully in whatever topology exists. A VSAN switch could also have several VSANs and connect to multiple non-VSAN switches over multiple E ports and ISLs. It is possible that these non-VSAN switches could all have their own independent fabrics. In this case, the topology would look like a hub with spokes, where each spoke represented a unique fabric connection. It is conceivable that an MDS switch could be used to connect to several ... Access >>>
