Figure 3-4. Distributed SA Multiple Virtual Fabrics Configured Example
Virtual Fabrics with Overlapping Definitions
As defined, SIDs should never be shared between Virtual Fabrics. Unfortunately,
it is very easy to accidentally create such overlaps. Figure 3-5 shows an example
with overlapping definitions.
Figure 3-5. Virtual Fabrics with Overlapping Definitions
In Figure 3-5, the fabric administrator enabled the “PSM_MPI” Virtual Fabric
without modifying the “Default” Virtual Fabric. As a result, the Distributed SA sees
two different virtual fabrics that match its configuration file.
In Figure 3-6, the person administering the fabric has created two different Virtual
Fabrics without turning off the Default - and two of the new fabrics have
overlapping SID ranges.
