Fabric profile

Fabric virtual fabrics subprofile
The fabric virtual fabrics subprofile models the partitioning of a physical fabric into one or more
logical fabrics. The physical fabric consists of one or more switches that can be partitioned. The
switch in the physical fabric that can be partitioned is called the partitioning system. The resulting
virtual fabric will consist of one or more switches formed from the partitioning systems. The
resulting virtual switch in the virtual fabric is called the partitioned system. The virtual fabric
topology, along with its virtual switches, is modeled as per the Fabric profile. The underlying
physical fabric topology, along with its partitioning systems, is modeled by the fabric virtual fabrics
subprofile. By using the Fabric profile with the fabric virtual fabrics subprofile, a logically separated
physical fabric can be discovered.
Fabric virtual fabrics form a single physical fabric. This scenario encompasses the following cases:
•
All virtual fabrics are discovered with dedicated ISLs between the base switches.
-
Brocade_SAN.Name is the principal WWN of the base fabric where all virtual fabrics have
been discovered.
-
In the absence of a dedicated ISL between the base switches, no actual logical fabrics
exist except for those that have a dedicated ISL. The virtual fabrics are disjointed.
•
All virtual fabrics are discovered with no dedicated ISLs between the base switches but
dedicated ISLs between logical switches.
•
Only some virtual fabrics are discovered exclusive of base fabric.
Registration
Each virtual fabric represented by an instance of Brocade_Fabric, is associated to an instance of
Brocade_RegisteredProfile(Fabric). By SMI definition, all virtual fabrics that are physically
interconnected belong to the same SAN. The Brocade_SAN instance containing the virtual fabrics
associates itself to an instance of Brocade_RegisteredSubprofile (FabricVirtualFabrics) only if the
base switch is discovered. Refer to
“Registration”
on page 18.
Data model
Figure 14
models the required classes. The classes relevant in the Fabric profile are also included:
•
Each physical switch is represented by an instance of Brocade_PhysicalComputerSystem.
•
Each physical port is represented by an instance of Brocade_PCSNetworkPort.
•
Each virtual fabric is represented by an instance of Brocade_Fabric.
•
Each virtual switch is represented by an instance of Brocade_Switch.
•
Each port within a virtual switch is represented by an instance of Brocade_SwitchFCPort.
•
All virtual fabrics associate to a single Brocade_SAN instance.
•
All virtual switches carved out from a single switch associate to a single
Brocade_PhysicalComputerSystem instance.
•
All Brocade_PhysicalComputerSystem instances associate to a single Brocade_SAN instance.
