Managing IP Storage Services
Cisco MDS 9000 Family switches can route FCIP and iSCSI IP storage services independently, allowing servers to connect to a storage network using Fibre Channel or IP. Using open-standard IP-based technology, the Cisco MDS 9000 Family IP storage services enable you to consolidate remote SAN islands using FCIP, and to extend SAN connectivity to IP-enabled servers using iSCSI protocols.
Fabric Manager allows you to configure and monitor FCIP and iSCSI storage services on multiple Cisco 9000 switches. Device Manager allows you to configure and monitor these services on a single Cisco 9000 switch.
For information about configuring FCIP and iSCSI storage services using the command-line interface (CLI), refer to the Cisco 9000 Family Configuration Guide.
To learn more about managing IP storage services, refer to the following topics:
•IP Storage Services Module
•Managing Gigabit Ethernet Interfaces
•Managing FCIP
•Managing iSCSI Services
IP Storage Services Module
The IP Storage Services (IPS) module must be installed in your Cisco MDS 9000 Family switch before you can manage FCIP and iSCSI services on that switch. It integrates seamlessly into the Cisco MDS 9000 Family, and supports the full range of services available on the switching modules, including VSANs, security, and traffic management. Traffic can be forwarded between any IP storage port and any other port on a Cisco MDS 9000 Family switch.
The IPs module can be used in any Cisco MDS 9500 or 9200 series switch, and has eight SFP Gigabit Ethernet (Gig-E) ports, and it is hot-swappable. Each port can run FCIP and iSCSI protocols simultaneously.
•FCIP — FCIP transports Fibre Channel frames transparently over an IP network between two Cisco MDS 9000 Family switches or other FCIP standards-compliant devices.
•iSCSI — The IPS module provides IP hosts access to Fibre Channel storage devices. The IP host-initiated SCSI commands are encapsulated in IP and sent to a Cisco MDS 9000 port. At this point, the commands are routed from the IP network into a Fibre Channel network and forwarded to the intended target.
Managing Gigabit Ethernet Interfaces
The Gigabit Ethernet ports on the IPS module can only be used to perform IP storage services like iSCSI and FCIP. This port does not bridge ethernet frames or route IP packets. A new port mode option, IPS mode, is defined for Gigabit Ethernet ports. IP storage ports are implicitly set to IPS mode (so they only perform IP storage functionality). You can use an IPS module to perform either iSCSI or FCIP storage services.
The Gigabit Ethernet interface must be configured with an IP address before it can perform IP storage services functions. When one Cisco MDS 9000 Family switch connects to another Cisco MDS 9000 Family switch via the IPS modules, the following apply:
•The two switches are connected through a virtual ISL running on the FCIP tunnel. The endpoints of the virtual ISL are two virtual E ports.
•The virtual E ports become virtual TE ports if trunking is enabled, and the connecting link is a virtual EISL.
Refer to the Cisco 9000 Family Configuration Guide if there are problems.
Procedures for configuring Gigabit Ethernet interfaces include:
•Configuring Gigabit Ethernet Interfaces
Managing FCIP
Fibre Channel over TCP/IP (FCIP) is a service that allows islands of Fibre Channel SANs to be interconnected over IP networks to form a unified SAN — a single Fibre Channel fabric. These connections are referred to as "FCIP tunnels."
This section describes two ways to create FCIP tunnels. You can use the Device Manager, or you can use the FCIP Wizard to create tunnels using the Fabric Manager. See the "Creating FCIP Tunnels with Fabric Manager" section for this information.
Procedures for creating and managing FCIP include:
•Assigning FCIP Profiles
•Creating Tunnels
•Verifying Interfaces
•Verifying Extended Link Protocols
•Checking Trunk Status
•Checking for Interface Errors
Managing iSCSI Services
Cisco MDS 9000 Family iSCSI storage services provide IP hosts with access to Fibre Channel storage devices as if each storage device were directly attached to the hosts. The switch transparently presents each IP host to the storage device as if each host were an Fibre Channel host. iSCSI services create virtual iSCSI targets and maps them to physical Fibre Channel targets available in the Fibre Channel SAN. It presents the iSCSI targets to IP hosts as if the physical targets were directly attached to the hosts. In conjunction with presenting iSCSI targets to hosts, iSCSI Service presents each IP host as an Fibre Channel host, i.e. Host Bus Adaptor (HBA) to the storage device. The storage device is aware of each IP host and responds to each IP host as if it were an Fibre Channel host connected to the storage device.
For more information on iSCSI services, see the Cisco 9000 Family Configuration Guide.

Step 1 Be sure you are connected to a switch that contains an IPS module.
Step 2 Open Device Manager.
Step 3 Select any Ethernet port by clicking on it once.
Step 4 Select Gigabit Ethernet Ports from the Interfaces menu. All Gigabit Ethernet ports for the switch are displayed in a table.
Step 5 To configure the alias, state, or IP address for a particular port, double-click on the appropriate table cell.
Step 6 Enter the alias, IP address, or state for the port.
Step 7 Click Apply.

Creating FCIP Tunnels with Device Manager
To create and manage FCIP tunnels with Device Manager, first verify that the IPS module is inserted in the required Cisco MDS 9000 Family switches, and that the switches' Gigabit Ethernet interfaces are connected and the connectivity verified using the ping command. The steps in creating FCIP tunnels are:
•Assigning FCIP Profiles
•Creating Tunnels
•Verifying Interfaces
Assigning FCIP Profiles
You can use Device Manager to configure FCIP tunnels between switches. First, you must create FCIP profiles, and then bind the interfaces to the profile. To bind an FCIP profile to an interface, use the IP address of the interface in the FCIP profile's IP address configuration. Profile numbers range from 1 to 255. The interface associated with a profile can be either of the following:
•EtherChannel
•Ethernet subinterface slot and port (or slot, port, and VLAN ID)
To create and bind profiles on a Gigabit Ethernet interface, follow these steps.
Step 1 Be sure you are connected to a switch that contains an IPS module.
Step 2 Open Device Manager.
Step 3 Select FCIP from the IP menu.
Step 4 Click the Profiles tab if it is not already selected. The FCIP Profiles dialog is displayed. Any profiles already bound, are listed in the table along with their IP addresses.
Step 5 To add a new profile, click Create. The Create FCIP Profiles dialog is displayed.
Step 6 Enter the profile ID in the ID field.
Step 7 Select an IP address of the interface to which you want to bind the profile from the IP Address dropdown list.
Step 8 Enter all the optional information, if desired.
Step 9 When finished, click Create to add this profile to the table. Click Close to exit the Create FCIP profiles dialog without adding the profile.
Note You can access the field descriptions for the windows or dialog boxes in this procedure in the Reference section of the Fabric Manager or Device Manager help systems.
