H-series switches
Table 4 lists the H-series switch and port maximums for specific topologies.
For large fabrics, the number of user ports is determined by use of SN6000 Fibre Channel Switches
and making maximum use of their dedicated 10Gb/20Gb stacking port ISLs, which leaves more of
the 8 Gb ports available for device connections.
