Storage Area Networking solutions use a number of
integrated infrastructure components to enable a
variety of storage applications. The solutions are
typically comprised of a number of disk storage arrays
and tape drives connected to a Fibre Channel (FC)
switch via FC links. The OPTera Metro 5200
Multiservice Platform enables service access delivery
providing the solution with flexibility and scalability.
Until recently, businesses transported most of their
data within Local Area Networks (LANs) at a single
location. Today this trend has reversed and more and
more traffic and protocol types are demanding
transport across public Metropolitan Area Networks
(MANs). Unfortunately, storage centric protocols such
as ESCON and FC are seldom handled by these
networks.
Nortel Networks Storage Area Networking solution
overcomes this problem, by transporting all of these
and other essential protocols in their native format to
interconnect an organisation’s critical storage devices.
The Storage Area Networking concept consists of
setting up a separate high-speed mesh network that
links servers and storage devices. Typically Fibre
