I poked around for the answer but could not find it.
What is the max port for a gig with 1 scp in it?
I've read with 2 scp modules in the switch for redundancy I can have a
max of 32 sas, 20 das or 24 sas and 8 das. Is this info still
correct?

The GIGAswitch/FDDI system has 14 slots, broken down as follows:
slots 1-4 two port slots
slots 5-6 four port slots
slot 7 unavailable - CLK module
slot 8 unavailable - CBS module
slots 9-12 four port slots
slots 13-14 two port slots
...so, there are six two port slots and six four port slots.
One of those slots must be occupied by an SCP - usually a two port
slot. Thus:
(6-1)*2 + 6*4 = 34 physical bridge ports available
This is the maximum number of SAS ports available.
The maximum number of DAS ports is obtained by putting all FGL-2s
in all the available (eleven) slots:
(12-1)*2 = 22 DAS ports available.
You may care to consult the "Logic Modules" section of the
GIGAswitch/FDDI System Manager's Guide for additional information.
