CN 4200 uses G6/F10A to
multiplex up to 4 STP

Can also mux STP w/
other data links (FICON,
ESCON, FC) for additional
wavelength efficiency

Challenges:
Solution:
Need to rate limit each port to ensure the WAN
router is not overrun
No rate limiting required
Bandwidth per storage array is limited (i.e. 25%
available if 4 storage arrays)
DBA dynamically adjusts bandwidth as needed
Need to complete a detailed assessment of the
IP network to ensure packet loss
Ciena ensure 0% packet loss therefore no
assessment required
GbE interfaces compress, require a
