  • Page 48: Fibre Channel Port Types

    Fibre Channel Switching Concepts Fibre Channel Port Types Fibre Channel standards use the term node to describe any device connected to one or more other devices over Fibre Channel. Each node has at least one port that connects to other ports in other nodes. There are several types of Fibre Channel port, some of which are shown in Figure 2-1.

  • Page 49: Device Discovery

    Fibre Channel Switching Concepts Device Discovery The discovery of storage devices by a SCSI Initiator on a Fast-Wide Differential cable is a well-defined process consisting of the Initiator incrementing through an arbitration/selection/Test Unit Ready cycle on up to 15 target IDs. As a result of this probe, the operating system device driver can initiate I/O to the discovered devices.

  • Page 50: Fabric Addressing

    Fibre Channel Switching Concepts Fabric Addressing Each N_Port attached to a fabric is assigned a unique 64-bit identifier called a World Wide Port Name (WWPN). WWPNs are factory-set on the HBAs in the hosts, and are generated on the Symmetrix Fibre Channel ports.

  • Page 51: Domain Id Assignment

    Fibre Channel Switching Concepts This address becomes the Source ID (SID) on the N_Port’s outbound frames and the Destination ID (DID) on the N_Port’s inbound frames. The fabric uses the DID to route each frame to its final destination. The Domain byte is used to determine the destination switch and the Area byte is used to determine the destination port for each frame.
  • Page 52 This will facilitate future fabric mergers, and is particularly important if zoning is implemented through port number (and by default Domain ID) rather than WWN. EMC recommends zoning by WWN. This allows moving fiber-optic cables from one port to another without invalidating the zoning configuration.

  • Page 53: Principal Switch Selection

    Fibre Channel Switching Concepts Principal Switch Selection Every multiswitch fabric contains one principal switch, which assumes domain address manager functionality, and controls the allocation and distribution of domain IDs for all switches in the fabric (including itself). A principal switch is selected through negotiation during the Build Fabric process that follows any of these occurrences: Multiple directors/switches are interconnected to form a fabric.
  • Page 54 When building a fabric of a two-tier architecture (backbones and edges devices, described in more detail under Two-Tier Architecture on page 4-23), EMC recommends configuring one of the Symmetrix tier backbones as the principal switch. This strategy has simplicity, reliability, and efficiency benefits.

  • Page 55: Fabric Wwn Assignment

    Fibre Channel Switching Concepts Fabric WWN Assignment The Connectrix Manager Fabric Manager application identifies fabrics using a fabric World Wide Name (WWN). The fabric WWN is the same as the WWN of the fabric’s principal switch. If a new principal switch is selected because of a change to the fabric topology, the fabric WWN changes to the WWN of the newly selected principal switch.

  • Page 56: E_Port Segmentation

    Fibre Channel Switching Concepts E_Port Segmentation When an ISL between two separate fabrics is connected, the two switches exchange operating parameters to determine if the switches are compatible and can join to form a single fabric. If the switches are incompatible, the connecting E_Port at each switch segments to prevent the creation of a single fabric.

  • Page 57: Fabric Services And State Change Notifications

    Fibre Channel Switching Concepts Fabric Services and State Change Notifications In a multiswitch fabric, switch-provided services such as Name Service, Registered State Change Notification (RSCN) requests, and Zoning are provided on a fabric-wide basis. For example, if a fabric-attached device queries a switch Name Server to locate all devices that support a specified protocol, the reply includes all fabric devices that support the protocol that are in the same Zone as the requesting device, not just devices attached to the switch.

  • Page 58: Classes Of Service

    Fibre Channel Switching Concepts Classes of Service The two classes of service typically used in the storage area network environment are Class 2 and Class 3. Class 2 provides acknowledged connectionless service and Class 3 provides unacknowledged connectionless service. For devices using Class 2 service, there is also a higher-level N_Port login process where the end ports establish a session and determine the flow control rules to be used between them.

  • Page 59: Persistent Binding

    Fibre Channel Switching Concepts Persistent Binding The upper levels of all device drivers used in a fabric environment were designed for parallel SCSI. The parallel SCSI I/O model assumed a small number of targets on a bus and a small number of LUNs (logical unit numbers) on each target.

  • Page 63: Bandwidth

    Fibre Channel Switching Concepts Bandwidth All Connectrix products are fully nonblocking, which means that any random set of port pairs can each operate at 100 MB/s or 200 MB/s full duplex without contention for resources or interference from the other port pairs. Whether the ports are on the same port card or are physically spread apart on the unit there will be no effect on throughput.

  • Page 67: Path Selection And Isl Loading

    Fibre Channel Switching Concepts Path Selection and ISL Loading Connectrix Directors and switches use a number of algorithms to distribute the load over a set of ISLs. These algorithms include: Shortest Path First Multiple Equal-Cost Paths Load Assignment on World Wide Node Names The ANSI standard for routing in a Fibre Channel fabric is Fibre Channel Shortest Path First (FSPF).

  • Page 68: Shortest Path First

    Fibre Channel Switching Concepts Shortest Path First In Figure 2-6, every source is only one hop away from its destination. If frames from an N_Port on Domain ID 1 are destined for an N_Port on Domain ID 3, the director routes these frames over one of the diagonal ISLs between those two directors.

  • Page 69: Load Assignment On World Wide Node Names

    Load Assignment on EC-1200-based directors and switches offer a unique load assignment World Wide Node algorithm. When configuring a fabric with a server that uses EMC Names PowerPath™, it is best to split the server’s links across fabrics. In some cases, however, multiple HBAs from a server may enter a fabric through the same domain.

  • Page 70: Frame Delivery Order

    The Rerouting Delay parameter can be enabled through the Connectrix Manager’s Product Manager. By default, the Rerouting Delay is disabled. EMC tests with Symmetrix and EMC-approved HBAs have shown no problems when frames arrive out of order. By leaving the delay parameter disabled, the servers and Symmetrix recovery much more quickly to events in the fabric.

  • Page 72: Zoning

    Zoning and Naming Zoning One aspect that makes switched fabrics so powerful is the ability of all devices attached to a fabric to communicate with each other. In a storage area network environment, however, this can create some manageability problems; for example, interoperability issues can arise between different types of hosts.
  • Page 73 HBA, no matter what policies it might follow. Until these switches are available, it is required that only EMC-approved HBAs and device drivers be used on a Connectrix fabric. Volume Logix™ provides protection for the storage devices, but does not provide protection for the Connectrix fabric from unsupported device drivers.

  • Page 74: V6.02 Zoning Capabilities

    • All devices not included as members of the active zone set are included in the default zone if Default Zoning is enabled. • The EMC manufacturing default (and the recommended practice) is to have Default Zoning disabled. This insures maximum isolation between all N_Ports during installation processes.
  • Page 75 Zoning and Naming Broadcast frames — Class 3 broadcast frames are transmitted to all N_Ports attached to the switch, regardless of zone membership. Maximum configurations: Association Parameter Maximum Fabric-wide Switches in one fabric Physical hops in one fabric ISLs domain to domain Connectrix Zone Sets per service processor Manager...
  • Page 76 Fibre Channel director hardware changes.) CAUTION EMC strongly discourages zoning by port numbers for many reasons. For example, if it becomes necessary to change the domain ID of a switch (or this is done automatically by the fabric), zones configured with port names will become invalid and may create undesirable consequences.

  • Page 77: Single-Hba Zoning

    Zoning and Naming Single-HBA Zoning EMC recommends the practice of single-HBA zoning in the Connectrix; that is, configuring each HBA with its own zone. Members of the zone would consist of the HBA and one or more Symmetrix ports with the volumes that will be used by the HBA.
  • Page 78 The single-HBA zoning capability depends on FC-SW functionality in the device driver. This capability is supported by the EMC-approved Solaris, Windows NT, and AIX device drivers. Not all future device drivers may support this capability. Check your driver’s manual for FC-SW configuration restrictions.
  • Page 79 Zoning and Naming Unpredictable results are likely to occur when multiple HBAs in the same server are configured in the same zone and the server is running PowerPath 2.0 or earlier. Single-HBA zoning with PowerPath 2.0 has proven to be a robust combination for path availability and load balancing.

  • Page 80: Merging Zoned Fabrics

    Zoning and Naming Merging Zoned Fabrics In a multiswitch fabric, the active zoning configuration applies to the entire fabric. Any change to the configuration applies to all devices in the fabric. When fabrics join through an ISL, adjacent directors exchange active zone configurations and determine if the configurations are compatible and can merge.
  • Page 81 Zoning and Naming If two fabrics successfully join, the new active zone set is in the fabric but is not in the Zoning Library of the service processor. To move the new active zone set to the Zoning Library, use the Save Active Zone Set command on the Zone Set view.

  • Page 82: Zone Naming - Character Set Considerations

    Zoning and Naming Zone Naming — Character Set Considerations The V3 Connectrix Manager character set requirements for the Zoning Library have changed with V4.x/6.x. The changes make the V4.x/6.x character set requirements compatible with the character set requirements established for Open Fabric 1.0.
