A DS8800 customer would like to implement synchronous remote mirroring on an DS8800 using their existing
dark fibre infrastructure between the two data centers. The related Disk Magic
model shows a very high expected replication rate between the two DS8800 systems.
Which technical aspect needs most to be considered during implementation?

A.
as long as there are configured separated ports for replication, no risk of insufficient bandwidth exists

B.
the DS8000 Metro Mirror synchronization speed should be adjusted in the GUI to the highest possible value

C.
ensure sufficient bandwidth is available in the dark fibre links

D.
configure FICON links for replication because these are faster
