Chapter 1 Before Configuring SN 5428-2 Storage Router Software
SN 5428-2 Storage Router Overview
Fibre Channel over IP (FCIP) enables SN 5428-2 Storage Routers to provide connectivity by tunneling through an IP network between storage area networks (SANs). (See Figure 1-3.)

In addition to providing services for accessing storage over IP networks, the SN 5428-2 Storage Router software provides the following services:
•VLAN Access Control—provides IP access control to storage based on a VLAN identifier (VID) number (in addition to access control through access lists)
•Authentication—provides iSCSI, Enable and Login authentication using AAA authentication methods
•High Availability (HA)—provides the ability to group storage routers in a cluster for intelligent failover and other cluster-related functions (for SCSI routing only)
•E_Port with FC Fabric Zoning—provides the ability to connect FC ports to FC switches and participate in fabric zoning, manage zoning, and support zone mergers
•SNMP/MIB support—provides network management of the SN 5428-2 through SNMP using selected MIBs
•Gigabit Ethernet Interface features—provides the ability to assign a management IP address per Gigabit Ethernet interface, multiple IP addresses per SCSI routing instance, and an optional secondary Gigabit Ethernet interface per IP address used for SCSI routing or SN 5428-2 management. When the SN 5428-2 is deployed for FCIP, provides primary and optional secondary Gigabit Ethernet interfaces to the FCIP peer.
•FCIP data compression—enables the SN 5428-2 to dynamically compress FCIP data traffic for better channel bandwidth utilization
•Buffer credit extension—enables the SN 5428-2 to donate buffer credits from a donor port to selected FC ports
•Secure Sockets Layer (SSL) support—provides HTTPS connection for secure access through the web-based GUI
•Secure Shell (SSH) protocol version 2 support—provides high encryption and authentication for interactive management sessions, and is a common replacement for Telnet
•Routing Information Protocol (RIP) listening support—allows the SN 5428-2 to learn dynamic routing using RIP (version 1 or version 2) listening
•Service Location Protocol (SLP) support—provides the ability to advertise targets of specified SCSI routing instances to initiators or servers that use SLP
•Internet Storage Name Service (iSNS) support—provides the ability to register iSCSI targets with an iSNS server, allowing iSCSI initiators to dynamically discover available storage targets
