    Introduction Introduction The Eclipse 2640 SAN Router (referred to as SAN Router in this manual) supports iSCSI, iFCP, and R_Port for trunking to both Internet Protocol (IP) backbones and legacy Fibre Channel (FC) fabrics. The SAN Routers connect to a wide range of end systems, including Fibre Channel, NAS, and iSCSI initiators and targets.

  • Page 39: Configuring Ip Addresses

    Configuring IP Addresses Configuring IP Addresses SAN Routers use the iFCP and iSCSI protocols, which use IP addresses for all routing and forwarding of storage traffic. Using the iFCP/iSCSI protocol, all Fibre Channel addresses are mapped to one or more IP addresses. You must configure two IP addresses with SAN Routers: the external iFCP/iSCSI network and the IP network.

  • Page 40: Internal And External Ip Addresses

    Configuring IP Addresses Figure 2-5 Internal and External IP Addresses A SAN Router has iFCP/iSCSI ports that are connected to the external IP network, and one or more ports that are connected to the internal IP network. Each TCP port connects to each network (both the internal and external networks) as an independent device.

  • Page 41: The Router Inband Ip Address

    Configuring IP Addresses Figure 2-5 shows the role and position of each IP address relative to the internal and external IP networks. The Router Inband IP Address The router inband IP address is used for the internal delivery of storage traffic. To configure the SAN Router inband address, use Configuration>System>Inband Address in the Element Manager.

  • Page 42: The Next Hop Gateway Ip Address

    Configuring IP Addresses Figure 2-7 FC/Ethernet Port Configuration Dialog Box The Next Hop Gateway IP Address The iFCP/iSCSI ports interact with the external IP network as if they were independent IP hosts. Each iFCP/iSCSI port needs a gateway address of an external router that can forward the storage traffic to the remote iFCP/iSCSI port.

  • Page 43: The Internal Ip Address

    Configuring IP Addresses The Internal IP Address Storage traffic that is to be transported through the external network by iFCP or iSCSI must first be delivered to the iFCP/iSCSI port that will perform the iFCP/iSCSI encapsulation. The internal IP address is used by the iFCP/iSCSI port to receive this storage traffic from the internal network.

  • Page 44: Guidelines When Working With Firewalls

    Configuring IP Addresses Figure 2-8 FC/Ethernet Port Configuration Dialog Box Guidelines When Working with Firewalls The iFCP and iSCSI protocols use TCP for transmission. TCP provides several benefits such as: • Retransmission of any packets dropped by the network. • Guaranteed in-order delivery.
  • Page 45 Configuring IP Addresses connection is established are the TCP segments allowed to be transmitted from the sender to the receiver. A firewall can be used to block the establishment of TCP for some applications while permitting other applications to transmit data. To accomplish this, firewalls frequently use a combination of TCP port numbers and IP addresses.

  • Page 110: Introduction

    Introduction Introduction SAN Routers support true gigabit wire-speed iSCSI-FC gateway functionality, which means they can translate iSCSI traffic to Fibre Channel traffic and vice versa. Using SAN Routers, iSCSI initiators can access FC storage devices as shown in Figure 5-1. The initiators and targets (FC or iSCSI) can be either directly connected to the SAN Router or connected across an FC or IP network as shown.
  • Page 111 Introduction Example Configuration Figure 5-2 The server in Figure 5-2 can either be directly connected to the SAN Router or indirectly connected via an intermediate IP network. For a direct-attached configuration, the server must be physically connected to the iSCSI-capable ports (13-16) on the SAN Router. When connected via an intermediate IP network, the server must have IP connectivity to one of the TCP ports on the SAN Router.

  • Page 133: Configuring Iscsi Authentication

    Configuring iSCSI Authentication Configuring iSCSI Authentication SAN Routers support CHAP-based authentication of iSCSI initiators in conjunction with an external RADIUS server. Challenge Handshake Authentication Protocol (CHAP) provides a type of authentication between an agent (typically a network server) and the client program. Both share a predefined secret, which they verify during an authentication login sequence.

  • Page 134: Sample Authentication Configuration

    Configuring iSCSI Authentication Sample Authentication Configuration Figure 5-13 A typical interaction would be as follows: 1. The iSCSI initiator creates a “portal” session with the SAN Router. 2. The iSCSI initiator is configured to use CHAP authentication. The password and username have been configured in the iSCSI initiator.

    Configuring iSCSI Authentication Using Static Routes If your RADIUS server is attached via the SAN Router's management port, then you need to add a static route to the RADIUS server to reach the TCP port's internal address. Refer to Figure 5-14 page 5-27.

  • Page 136: Using Radius Authentication

    Configuring iSCSI Authentication If you are having problems authenticating iSCSI login requests, make sure that the RADIUS server has logical connectivity to the iSCSI port address. You can confirm this with a ping to the internal address from the RADIUS server (ping 10.10.10.11). If the ping fails, iSCSI initiator will never receive the authentication grant.

  • Page 137: Advanced Tcp Configuration

    Configuring iSCSI Authentication 3. Enter the UDP port on the RADIUS server to send the authentication requests. The RFC 2865 defaults this port to 1812, but can be different for other implementations. 4. Enter the timeout value in seconds. This is the timeout for each retry.
