IP Services Overview
The Cisco MDS 9000 NX-OS software provides features such as FCIP, SAN Extension Tuner, iSCSI, IP
storage, IPv4, and IPv6 in a single platform. These IP services simplify SAN provisioning by
automatically distributing configuration information to all the switches in a storage network. The Virtual
Routing Redundancy Protocol (VRRP) increases the IP network availability for iSCSI and FCIP
connections by allowing failover of connections from one port to another. The increased IP network
availability facilitates the failover of an iSCSI volume from one IP services port to any other IP services
port, either locally or on another Cisco MDS 9000 switch.

FCIP
FCIP (Fibre Channel over IP Protocol) transparently connects a remote Fibre Channel storage area
networks (SAN island) by transporting Fibre Channel data from a local SAN to a remote SAN using IP
networks. IP network availability for the FCIP connections can be increased by using features such as
Virtual Routing Redundancy Protocol (VRRP) and quality of service (QoS). FCIP can be optimized for
wire performance through enhancements that address out-of-order delivery issues, support jumbo
frames, provide traffic shaping, and perform TCP optimization.
