FCIP Network Structures

This section describes typical FCIP network structures. In all of these examples a
management station (not shown) manages the storage routers through an IP
network connected to the management interface and/or HA interface of each
storage router.

configuration. In this example an FC host or FC device connects to one or more
Fibre Channel interfaces of each peer SR2122-2 Storage Router deployed for
FCIP. Each SR2122-2 connects to the IP network through one of its Gigabit
Ethernet interfaces. Through the IP network each FCIP instance accesses its peer,
thereby connecting the SANs.

configuration. In this example configuration, an FC host or FC device connects to
one or more Fibre Channel interfaces of each peer SR2122-2 Storage Router
deployed for FCIP, and each SR2122-2 connects to two separate IP networks
through each of its Gigabit Ethernet interfaces. Through the IP network, each
FCIP instance accesses the peer storage router deployed for FCIP, connecting the
SANs. In this configuration, IP A and IP B are redundant paths, so that the loss of
connectivity via either path does not cause a loss of connectivity between the
SANs.

SR2122-2 Storage Routers provide full redundancy. In this configuration, loss of
an SR2122-2 or loss of connectivity through one of the IP networks can be
tolerated with no loss of connectivity between the SANs.
