Fcip Overview; Using Fcip To Route Fibre Channel Packets - HP StorageWorks SR2122 User Manual

FCIP Overview

Fibre Channel over IP (FCIP) enables SR2122-2 Storage Routers to provide
connectivity between FC hosts and FC storage devices over an IP network.
To deploy FCIP, two SR2122-2 Storage Routers are required. Each system is
configured for FCIP and connected to a SAN (or to any FC host or FC device).
The peer systems are connected to each other through an IP network.

Figure 36: FCIP Overview
An FC host or FC device needs no additional hardware or software to access
storage devices via an SR2122-2 Storage Router deployed for FCIP.
To configure an SR2122-2 Storage Router deployed for FCIP you need a basic
understanding of the following concepts:

Using FCIP to Route Fibre Channel Packets

With FCIP, peer systems transport FC frames over an IP network. From the
perspective of the SANs the storage devices accessed through the peer systems
appear to be part of one unified SAN.
Once configured, FCIP instances on each system become active and establish
their connectivity via the IP network. The storage devices in one SAN access the
storage devices in the connected SAN using FC frames, which are encapsulated in
IP packets by the FCIP instance, and transmitted to the peer system. The peer
FCIP instance strips the IP packet data and passes only the FC frames over the FC
interfaces to the storage devices.
