Figure 2 Cascaded fabric . 25090a Switch models All HP Fibre Channel switches are supported for use in a cascaded fabric topology. Cascaded fabric topologies typically use the SN6000 Fibre Channel Switch; the 8/20q Fibre Channel Switch (or the HP Simple SAN Connectivity Kit); or SAN, Fabric, or Edge switches, which support smaller incremental growth. NOTE: Over time, a cascaded fabric topology can result in increased hops between switches. H-series, B-series, and C-series fabrics must not exceed seven hops; M-series fabrics must not exceed three hops. For additional switch hop information, see: • "H-series switches and fabric rules" on page 83 • "B-series switches and fabric rules" on page 93 • "C-series Fibre Channel and FCoE switches and fabric rules" on page 135 • "M-series switches and fabric rules" on page 157 Benefits The benefits of a cascaded fabric include: • Ability to connect SANs in diverse geographic locations 38 SAN fabric topologies
