Limitations and restrictions of Virtual Fabrics

The maximum number of Logical Switches per chassis varies depending on the switch model.
the supported platforms and the maximum number of Logical Switches (including the default Logical
Switch) supported on each.

The following are restrictions on the default Logical Switch in the HP StorageWorks DC SAN Backbone
Director and HP StorageWorks DC04 SAN Director:
• Cannot use extended ISLs (XISLs)
• Cannot be a base switch
XISL use is not permitted in any of the following scenarios:
• The Logical Switch is FICON CUP enabled.
• The Logical Switch is operating in interoperability mode 2 or 3.
• The Logical Switch has ICL ports.
• The Logical Switch is an edge switch for an FC router.
The Logical Switch is using GbE ports (VE_Ports).
•
• The Logical Switch is the default Logical Switch in the HP StorageWorks DC SAN Backbone Director or
the HP StorageWorks DC04 SAN Director.
To allow or disallow XISL use for a Logical Switch, see
page 187.
Interaction with Virtual Fabrics
In interoperability modes 2 and 3, you cannot use XISL in the Logical Fabric. The
Logical Switches must be connected only with ISLs.
Licenses are required for all Logical Switches in a chassis.
Performance monitors are supported in a limited number of Logical Switches,
depending on the platform type. See Chapter 18,
performance monitoring" on page 405 for more information about performance
monitoring when Virtual Fabrics are enabled.
Port mirroring is not supported when Virtual Fabrics is enabled.
QoS VCs are maintained across the base fabric. See Chapter 16,
fabric behavior" on page 339 for more information about using the Adaptive
Networking features with Virtual Fabrics.
Traffic Isolation zones with failover disabled are not supported in Logical Fabrics.
See Chapter 16, "Optimizing fabric
information about using TI zones with Virtual Fabrics.
