Virtual Connect fabrics 146
• You can attach up to four HP 3PAR storage systems directly to the VC FlexFabric module using a single
VC SAN fabric. This limitation is due to the number of FC-capable uplink ports available on the
FlexFabric module.
Mixed FabricAttach and DirectAttach VC SAN fabrics
Mixing FabricAttach and DirectAttach VC SAN fabrics is fully supported in the same Virtual Connect domain.
This scenario can be useful if you need to attach additional storage systems that are not supported today with
the DirectAttach fabrics.
