  • Page 93: Private Device Connectivity

    Planning Considerations for Fibre Channel Topologies • Private device - A loop device that cannot transmit an FLOGI command to the switch nor communicate with fabric-attached devices is a private device. As shown in Figure 3-4, device D is a private loop device connected to a Sphereon 4500 Switch and cannot communicate with any fabric-attached device.

    Planning Considerations for Fibre Channel Topologies Private devices only communicate with other devices on the same arbitrated loop, and interconnected public and private devices can communicate with each other. Such intermixed devices establish operating parameters and loop topology configuration through a port login (PLOGI) command exchange, rather than through the switch’s name server.

    Planning Considerations for Fibre Channel Topologies • Heterogeneous fabric - Vendor interoperability in the fabric environment is supported; therefore, fabric elements can include directors, fabric switches, and open-fabric compliant products supplied by original equipment manufacturers (OEMs). To determine if interoperability is supported for a product or if communication restrictions apply, refer to the supporting publications for the product or contact McDATA.
  • Page 107 Planning Considerations for Fibre Channel Topologies • Distance requirements - The distance between elements in a fabric affects the type of optical port transceiver and cabling required. In addition, variables such as the number of connections, grade of fiber-optic cable, device restrictions, application restrictions, buffer-to-buffer credit limits, and performance requirements can affect distance requirements.
  • Page 108: Isl Transfer Rate Versus Fabric Port Availability (Two-Director Fabric)

    Planning Considerations for Fibre Channel Topologies • Bandwidth - ISL connections can be used to increase the total bandwidth available for data transfer between two directors or switches in a fabric. Increasing the number of ISLs between elements increases the corresponding total ISL bandwidth but decreases the number of port connections available to devices.
  • Page 109 Planning Considerations for Fibre Channel Topologies • Preferred path - Preferred path is an option that allows a user to configure an ISL data path between multiple fabric elements (directors and fabric switches) by configuring the source and exit ports of the origination fabric element and the Domain_ID of the destination fabric element.
  • Page 110 Planning Considerations for Fibre Channel Topologies • Zoning - For multiswitch fabrics, zoning is configured on a fabric-wide basis. Changes to the zoning configuration apply to all directors and switches in the fabric. To ensure the zoning configuration is maintained, certain rules are enforced when two or more elements are connected through ISLs to form a fabric or when two or more fabrics are joined.

  • Page 113 Planning Considerations for Fibre Channel Topologies When multiple minimum-hop paths (ISLs) between fabric elements are detected, firmware balances the data transfer load and assigns ISL as follows: — The director or switch assigns an equal number of device entry ports (F_Ports) to each E_Port connected to an ISL. For example, if a fabric element has two ISLs and six attached devices, the load from three devices is transferred through each ISL.
  • Page 114 Planning Considerations for Fibre Channel Topologies • E_Port segmentation - When an ISL activates, the two fabric elements exchange operating parameters to determine if they are compatible and can join to form a single fabric. If the elements are incompatible, the connecting E_Port at each director or switch segments to prevent the creation of a single fabric.

    Implementing SAN Internetworking Solutions Implementing BC/DR Solutions The post-9/11 business environment requires corporations to protect critical data by implementing cost-effective business continuity and disaster recovery (BC/DR) solutions. These BC/DR solutions drive the requirement to extend local data center SANs to geographically distant locations.
  • Page 181: Extended-Distance Operational Modes

    Implementing SAN Internetworking Solutions • Reliability - Local storage traffic requires high-reliability communication and is intolerant of data loss, out-of-order packet receipt, or data retransmission. WANs typically provide best- effort communication service and rely on upper-level protocols for end-to-end transport. Because of these differences, a protocol conversion approach is usually required to integrate Fibre Channel SAN traffic over a geographically-dispersed network.
  • Page 182 Implementing SAN Internetworking Solutions • Synchronous data replication (SDR) - This operational mode ensures a remote data copy (identical to the primary copy) is created at the time the primary data is created. An update operation does not complete until confirmed at both the primary and mirrored sites.

    Physical Planning Considerations Security Provisions Security provisions are available to restrict unauthorized access to a director, switch, or attached Fibre Channel devices. Access to the director or switch (through the SAN management application, Element Manager application, or SANpilot interface) is restricted by implementing password protection.
  • Page 222: Santegrity Authentication

    Physical Planning Considerations System administrators can use the SAN management application to assign remote workstation access to directors and switches. Remote sessions are allowed for anyone on a customer intranet, disallowed completely, or restricted to specific workstations. Remote users must log into the SAN management application with a user name and password, just as when logging in to the local management server.
  • Page 223 Physical Planning Considerations The fabric element transmits a random value (used only once), an ID value (incremented at each login), and a shared CHAP secret (16-byte random value) to the server. The server concatenates the random value, ID value, and CHAP secret, and calculates a one- way message digest (also called a hash value).
  • Page 224 Physical Planning Considerations • RADIUS server support - Remote authentication dial-in user service (RADIUS) is a client-server, UDP-based protocol that supports storage and authentication of passwords and CHAP secrets. Directors, fabric switches, and SAN routers support a RADIUS client (LAN-connected to a primary or secondary RADIUS server) that authenticates CHAP responses and login passwords.

  • Page 229: Preferred Path

    Physical Planning Considerations Preferred Path The preferred path option allows a user to specify and configure one or more ISL data paths between multiple directors or fabric switches in a fabric. At each fabric element, a preferred path consists of a source port on the director or switch being configured, an exit port on the director or switch, and the Domain_ID of the destination director or switch.
  • Page 230 Physical Planning Considerations A preferred path is configured between a source server and destination device (A or B), traversing Director 1, Director 2, and Director 3. To configure the preferred path through the first director: 1. Select the Preferred Path option from the Element Manager application’s Configure menu.
  • Page 231: Zoning

    Physical Planning Considerations Zoning Directors and fabric switches support a user configuration that partitions attached devices into restricted-access groups called zones. Devices in the same zone can recognize and communicate with each other through switched port-to-port connections. Devices in separate zones cannot recognize name server or route table information and therefore cannot communicate with each other.
  • Page 232 Physical Planning Considerations Zones are configured through the SAN management application (SANavigator 4.2 or EFCM 8.6) by authorizing or restricting access to name server or route table information (depending on the firmware release level) associated with device N_Ports that attach to director or switch fabric ports (F_Ports).
  • Page 233 Physical Planning Considerations ATTENTION ! If zoning is implemented by WWN, removal and replacement of a device HBA or Fibre Channel interface (thereby changing the device WWN) disrupts zone operation and may incorrectly exclude a device from a zone. • The domain identification (Domain_ID) and physical port number of the director or fabric switch port to which the device is attached.
