2.1 Application Overview
The primary purpose of the OptiStar EdgeSwitch is to enable seamless interconnection of remote Fibre Channel
storage area networks (SAN) over IP-based metropolitan (MAN) and wide area (WAN) networks. Key
applications include off-site data backup, disaster recovery, data replication/mirroring and storage hosting. The
OptiStar EdgeSwitch employs the Fibre Channel over IP (FCIP) protocol to encapsulate Fibre Channel storage
traffic into IP for transmission across regional networks or long distance backbones.
Through FCIP, the OptiStar EdgeSwitch allows customers to leverage the best of both worlds: Fibre Channel
for block-level storage networking, and IP for MAN/WAN internetworking. This solution provides an easy and
cost-effective way to extend SAN applications over global distances, providing the storage networking
performance and data protection that today’s businesses demand.
Shown below is a simple, generic architecture for an OptiStar EdgeSwitch FCIP application that interconnects
two remote SANs over an IP MAN/WAN. Each OptiStar EdgeSwitch connects to the IP WAN via a WAN
module port, which could be Gigabit Ethernet, OC-48c/STM-16c or OC-12c/STM-4c Packet over
SONET/SDH. The SAN at each site connects to a Fibre Channel switch port on the OptiStar EdgeSwitch FCIP
Network Module.
