As far as I know the 5300 contains nine Goldeneye 2 ASICs. Each ASIC provide 24 ports.
5 Frontend ASICs for FC connectivity and 4 ASICs for backend.
On each Frontend ASIC is connected with two 8Gbit links to each backend ASIC.
Frontend ASIC: 16 Fronend port + 2*4 Backend ports = 24 ports
5 Frontend ASICs * 16 Frontend Port = 80 Ports
The topology is like core edge design.
I hope this helps.
If you are happy with this information please mark the thread as correct or helpfull.

Goldeneye 2 ASIC provide 32 ports not 24 ports.
16 front-end ports + 16 ( 4×4 not 2×4 ) back-end ports = 32 Ports.
Internal link speed 32Gbps = 4x8Gbps which is clearly visible from the GE2 Architecture.Internal links between ASICs enables 1:1 subscription ratio.
On Brocade 300 , 5410 ( 12-port embedded ) and 5470 ( 20-port embedded ) switches simply the remaining ports unused.
