l For Fibre Channel networks:
– The two data centers can be directly
connected using bare fibers if their
distance is within 25 km. Ensure that the
storage and application layers each have
at least two pairs (four wires) of bare
fibers for heartbeat interconnection in the
cluster.
– If the data centers are greater than or
equal to 25 km apart, use dense
wavelength division multiplexing
(DWDM) devices to interconnect them.
l For IP networks:
– The two data centers can be directly
connected using bare fibers if their
distance is within 80 km. If core switches
are deployed, ensure that at least two
pairs (four wires) of bare fibers are
connected to the core switches for
HyperMetro mirroring at the storage
layer and heartbeat interconnection at the
application layer.
– If the data centers are greater than or
equal to 80 km apart, use DWDM
devices to interconnect them.
If IP networking is used for the application
layer, ensure that the Fiber Channel network
with at least two pairs (four wires) of optical
cables is set up for heartbeat interconnection in
the cluster.
