Third-party QoS and data encryption FCIP products

Third-party vendors provide two classes of FCIP solutions that complement hardware: QoS devices
and IP data encryption devices. Detailed information about these products is available at the vendor
websites.

FCIP QoS products

You may need additional hardware to improve the QoS for an existing IP network. This hardware lets you use
the existing network with an FCIP gateway.

Fibre Channel over SONET

You can connect local SANs with a SONET to create an extended SAN.
An FC-SONET gateway resides at the end of an inter-site link. Each FC-SONET gateway encapsulates
Fibre Channel frames into SONET packets before transmitting the frames over the network. Upon
receiving the packets, another FC-SONET gateway extracts the original Fibre Channel frames from
the SONET packets and retransmits them to the destination Fibre Channel node.
The FC-SONET gateway also handles SONET-level error recovery.

FC-SONET IP link configurations

Using FC-SONET, you can configure the SANs through a single link, dual links, or shared ISL links.
FC-SONET dual-link configuration
A dual-link configuration is the benchmark for disaster protection
other link temporarily handles all data replication. For enhanced fault tolerance, you use two IP
providers, accessing the data center through two links.
