SAN Extension Tuner
The SAN Extension Tuner (SET) feature helps you optimize FCIP performance by generating Small
Computer System Interface (SCSI) I/O commands and directing the traffic to a specific virtual target.
SET reports the I/Os per second and I/O latency results, which helps you to determine the number of
concurrent I/Os needed to maximize the FCIP throughput.
For information on configuring the SAN Extension Tuner, see
Extension Tuner."
iSCSI
The iSCSI feature allows an IP host to access Fibre Channel storage. This feature enables routing iSCSI
requests and responses between iSCSI hosts in an IP network and Fibre Channel storage devices in the
Fibre Channel SAN. The Fibre Channel Storage devices are accessible from any Fibre Channel interface
of the Cisco MDS 9000 Family switch.
For information on configuring iSCSI, see
IP Services
The IP Services Modules allow you to extend storage networks using the Ethernet infrastructure. The
Cisco MDS 9000 Family switches route IP traffic between Ethernet and Fibre Channel interfaces. The
IP static routing feature is used to route the traffic between VSANs.This chapter also describes the
procedure to configure IP Route using Fabric Manager And Device Manager. From NX-OS release
4.2(1) and later, CPP interfaces are also available for selection while creating a new IP route.
For information on configuring IP services, see
IP Storage
The IP Storage (IPS) Service module allows you to use the open-standard FCIP protocol to enable
interconnection of SAN islands over extended distances. The IPS module and the MPS-14/2 module
allow you to use FCIP and iSCSI features. Both modules integrate seamlessly into the Cisco MDS 9000
Family, and support the full range of features that are available on other switching modules, including
VSANs, security, and traffic management.

IPv4 and IPv6
The Cisco MDS 9000 NX-OS software supports the IP version 4 (IPv4) and version 6 (IPv6) protocols
on Gigabit Ethernet interfaces. The architecture of IPv6 has been designed to allow existing IPv4 users
to transition easily to IPv6, while providing services such as end-to-end security, quality of service
(QoS), and globally unique addresses. The dual stack approach for IPv4 and IPv6 allows Cisco MDS 9000
Family switches to connect to older IP networks, transitional networks of both versions, and IPv6 data
networks.
