  • Page 7: Fcoe Overview

    FCoE overview Storage area network According to the Storage Networking Industry Association dictionary, "a storage area network (SAN) is any high-performance network whose primary purpose is to enable disk devices to communicate with computer systems and with each other." A SAN enables the universal connectivity of servers and disk devices. Compared to the conventional client/server computer system, a SAN allows the servers to share data and directly access data created by one another without having to copy it, improves storage scalability, and centralizes the management of data backup, access, and security.

  • Page 8: Fc Protocol

    FC protocol The servers, FCF switches, and disk devices in an FC SAN must all support FC. Basic concepts The World Wide Name (WWN) is a 64-bit address that identifies a fabric or an entity (such as an FCF switch, node, or port) in an FC SAN. The upper-layer protocol of FC uses WWNs for communication. Each entity has a factory-assigned globally unique WWN.

  • Page 9: Communication Flow

    Figure 3 Port modes The interface on a node is called an "N_Port." An FCF switch provides the following types of ports: F_Port—Connects to an N_Port or an NP_Port on another FCF switch. E_Port—Connects to an E_Port on another FCF switch. NP_Port—Connects to an F_Port on another FCF switch.

  • Page 10: Vsan

    After the server obtains the FC address of the disk device, the server can send FC frames (with the FC address of the disk device as the destination FC address) to the FCF switch nearby. When the FCF switch receives the FC frame from the server, it queries its FIB table for a data forwarding path according to the destination FC address, and forwards the FC frame to the next-hop FCF switch.

  • Page 11: Basic Concepts

    Figure 5 FCoE for I/O consolidation As shown in Figure 5, in the traditional network, the server is connected to the LAN through an Ethernet interface and to the SAN through an FC interface. In the FCoE network, the server is connected to the FCoE-capable FCF switch, and then the FCF switch is connected to the LAN through an Ethernet interface and to the SAN through an FC interface.

  • Page 12: How Fcoe Works

    You can connect either an ENode or an FCF switch to a VFC interface. VFC interfaces support E mode, F mode (default), and NP mode. The virtual node (VN) interface is a logical interface on an ENode to simulate the function of a physical FC interface.

  • Page 13

    NOTE: This section describes how FCoE works only on the FCF switch, rather than on the ENode. Procedure for receiving and sending FC frames over Ethernet An FC frame is transmitted over Ethernet using the following workflow: • FIP establishes a virtual link between the VFC interface of the FCF switch and the VN interface of the ENode or between VFC interfaces of two FCF switches.

  • Page 14: Fcoe Modes

    If it is bound, the switch checks whether the FCoE MAC address matches the bound FCoE MAC address. If they match, it replies with a solicited Discovery Advertisement, whose fcf priority field carries the FCF priority of the VFC interface. If they do not match, it discards the Discovery Solicitation.

  • Page 15: Npv Mode

    Figure 10 FCF network diagram In an FCoE environment as shown in Figure 10, different from a pure FC network, the ENode and FCF switch communicate over Ethernet interfaces on a lossless Ethernet network. The FCoE virtual link between the ENode and FCF switch connects a VN interface to a VFC interface, and the FCoE virtual link between FCF switches connects two VFC interfaces.

    FCoE configuration guidelines The switch supports FCoE only when operating in advanced mode. For more information about system operating modes, see Fundamentals Configuration Guide. FCoE features supported by different FCoE modes The switch supports two FCoE modes: FCF mode and NPV mode. Each mode has different features as shown in Table 1.

    replaces the locally-record principal switch information with the principal switch information recorded in the packet, and notifies the other switches. Finally, all switches in the network make an agreement on which switch is the principal switch. When the PSST times out, if the locally-recorded principal switch information is the local switch, the switch becomes the principal switch.

  • Page 44: Configuring Fc Routing And Forwarding

    Configuring FC routing and forwarding Overview Routing and forwarding in an FC SAN is achieved through FCF switches. When an FCF switch receives a packet, an FCF switch selects an optimal route based on the destination address and forwards the packet to the next FCF switch in the path until the packet reaches the last FCF switch, which forwards the packet to the destination node.

  • Page 45: Direct Routes

    Protocol—Protocol type, which can be DIRECT (direct routes), STATIC (static routes), or FSPF (FSPF • routes). Preference—There might be direct routes, static routes, and FSPF routes to the same destination. All • of these types of routes are assigned preferences. Direct routes have a preference of 0, static routes have a preference of 10, and FSPF routes have a preference of 20.

  • Page 46: Fspf Routes

    However, the static routes cannot automatically adapt to network topology changes. When the network fails or the network topology changes, the routes might fail to be reachable, and the network is interrupted. In this case, you must manually modify the static routes. Static routes support equal-cost routes.

  • Page 47: Configuring Static Routes For Fc

    After receiving an LSU, a switch needs to acknowledge its LSR with an LSA. Otherwise, the neighboring switch retransmits the LSR. How FSPF works FSPF works as follows: The switch periodically sends hello packets to establish neighbor relationships with other switches. After establishing neighbor relationships, the switches synchronize LSDBs by exchanging all LSRs in their respective LSDBs.

  • Page 59: Configuring Fc Zones

    Configuring FC zones Overview The VSAN technology divides a physical SAN into multiple VSANs, which are separated from one another, and provides more secure, reliable, and flexible services. A VSAN, however, cannot perform access control over the servers and disk devices (or the N_Ports) connected to a fabric. N_Ports in the same VSAN can access one another only if these N_Ports register name services.

  • Page 60

    Each VSAN can have multiple zone sets, each zone set can have multiple zones, and each zone • can have multiple zone members. To facilitate configuration, zone membership configuration supports use of zone aliases. A zone • alias is a set of N_Ports, which can be considered as a whole. You can add common zone members in multiple zones to a zone alias, and call the zone alias in different zones to simplify configuration.

  • Page 61: Distributing Zones

    Default zone The N_Ports in zones of the active zone set are part of the active zone set. Registered N_Ports that are not in the active zone set automatically become part of the default zone. If members of the default zone are allowed to access each other, the default zone can be considered to be part of the active zone set, and it participates in access control among N_Ports.

    Configuring NPV Overview NPV enables an FC SAN to accommodate more than 239 switches. NPV switches forward traffic from nodes to the core switch. Figure 25 shows a typical NPV network diagram. Figure 25 NPV network diagram NOTE: An NPV switch must be directly connected to the core switch. Downlink interface and downlink A downlink interface, also known as a server interface, is an interface through which an NPV switch connects to a node.

  • Page 75: Downlink-to-uplink Interface Mappings

    Downlink-to-uplink interface mappings NPV switches automatically map downlink interfaces to uplink interfaces. Before a downlink interface is brought up, the NPV switch maps it to the uplink interface with the minimum load among all operational uplink interfaces. The load here indicates the number of downlink interfaces mapped to the uplink interface.

    To configure an uplink interface: Step Command Remarks Enter system view. system-view Enter VFC interface interface vfc This interface is connected to the core switch. view. interface-number Configure the VFC By default, a VFC interface on an NPV switch interface to operate fc mode np operates in F mode.

    Configuring FC ping Overview In an FC SAN, use the fcping command to check whether a destination address is reachable and to test network connectivity. The FC ping works as follows: the source device sends an echo request to the destination device and determines whether the destination is reachable based on whether it receives an echo reply.

    Configuring FC tracert Overview In an FC SAN, use the fctracert command to obtain bidirectional routing information between source and destination, and check the network connectivity. You can use this feature to identify failed nodes and test network connectivity. FC tracert comprises two processes: Uplink process—In this process, beginning from the source, each switch along the path to the •...

    Switch A adds its uplink path information (including its WWN and domain ID) to the STR request packet and sends the packet to the next hop Switch B. After receiving the packet, Switch B replies with an STR ACC packet to Switch A. Switch B adds its uplink path information to the received STR packet and sends it to the destination switch, Switch C.
