Understanding VTL Zoning
Zoning is the crucial first step when integrating a storage system, such as the VTL
appliance, into a Fibre Channel storage area network (SAN). While specific zoning
recommendations must vary from SAN environment to SAN environment, this
chapter describes the basic requirements that all successful VTL deployments must
address.

Zoning for standard‐availability systems
The basic zoning requirement for VTL solutions that do not implement the high‐
availability feature is that each SAN zone contain only one initiator and one target,
as shown in the figure below.
You zone standard‐availability VTL systems the same way, regardless of the type of
zoning you use. In a soft‐zoned SAN, each target and initiator is defined by a logical
World Wide Port Name (WWPN), while in a hard‐zoned SAN, target and initiator
are defined by physical port numbers. But, in either case, you have one client
initiator and one VTL target per zone.
