An application is running in a data center as a set of virtual machines (VMs)...

Only the physical host can logically connect lo the SAN fabric, thus enhancing security

The number of FLOGIs is kept at a reasaonable level, and therefore cannot saturate the SAN fabric

Inter VSAN traffic can be switched by the HBA

Each VM initiator can be managed independently, since it will generate its own FLOGI, and have its own pWWN.
