If you have a need to support multiple data centers, you may want to extend
your management network to those other data centers. (Remember that serial
lines have fairly limited distances, and it is easier to extend an ethernet
network than to extend serial lines.)
If you have additional fiber pairs between the data centers, you can do this
with media converters.
Adding capacity for parallel networks between data centers is an expensive
project. The commitments for your fiber may extend to your security needs,
telecom systems, and more.
Even if you have enough capacity today, your needs may change in the future.
Since you are extending a management network, you should try to think into
the future, and plan for a connection that will stand the test of time.
