  • Page 17: Latency Guideline

    FICON concepts Latency guideline The maximum supported distance for a FICON channel is 300 Km (1.5 msec of delay). Synchronous mirroring applications are generally limited to 100 Km (0.5 msec of delay). Greater distances require that the FICON Acceleration feature be used with FCIP. The FICON Acceleration feature emulates control unit response to the channel to make the devices appear closer to the channel than they actually are.
  • Page 18 FICON concepts • FICON Control Unit Port (CUP) The internal port in a switch that assumes an FC address such that it is the FC DID used to direct FICON traffic to the FICON Management Server. • FICON Manager Host communication includes control functions such as blocking and unblocking ports, as well as monitoring and error-reporting functions.

  • Page 19: Ficon Configurations

    FICON configurations • Sysplex In IBM mainframe computers, a Systems Complex, commonly called a sysplex, allows multiple processors to be joined into a single unit, sharing the same sysplex name and Couple Data Sets. FICON configurations There are two types of FICON configurations that are supported using Brocade Fabric OS: switched point-to-point and cascaded topologies.

  • Page 20: Cascaded Ficon

    FICON configurations Cascaded FICON Cascaded FICON refers to an implementation of FICON that uses one or more FICON channel paths whereby the domain ID of the entry switch is different than the domain of the switch where the control unit is attached. Therefore, cascading requires a 2-byte link address. Any time a 2-byte link address is defined on a channel, all link addresses must be 2-byte link addresses.
  • Page 21 FICON configurations • The mainframes must be zSeries machines or System z processors: z196, z114, z800, 890, 900, 990, z9 BC, z9 EC, z10 BC, EC, and zEC12. Cascaded FICON requires 64-bit architecture to support the 2-byte addressing scheme. Cascaded FICON is not supported on 9672 G5/G6 mainframes.

  • Page 22: Access Control In Ficon

    Access control in FICON Access control in FICON Zoning is used to control access in a FICON environment. A zone consists of a group of ports or WWNs. Connectivity is permitted only between connections to the switch that are in the same zone. There are three types of zoning: WWN, port, and domain index zoning.
  • Page 23 Access control in FICON FIGURE 7 Complex cascaded zoning Blue Zone A: Any CHPID connected to Director 1, except CHPID 79, can get to any control unit connected to Director 1. The zone includes all ports in Director 1 except ports 4, 5, and 6. Orange Zone B: Any CHPID connected to Director 2, except CHPID 7A, can get to any control unit connected to Director 2.

  • Page 24: Error Reporting

    Access control in FICON Error reporting Non-implicit (such as Fabric OS recognized or bit error rate threshold exceeded) and implicit (FRU failure) link incidents are reported to registered listeners on the local switch. The RMF 74-7 record (FICON Director Activity Report, which is the same RMF Record containing the average frame pacing delay information) reports port errors, which in turn are also reported back to the mainframe host management consoles.

  • Page 28: Link And Fc Addressing

    Link and FC addressing Link and FC addressing To understand the addressing mode requirements and restrictions for FICON it is important to understand the relationship between the link address and the FC address. Understanding this relationship is also valuable for troubleshooting paths. Figure 9 represents components of link and FC addresses that are explained in this section.
  • Page 29 Link and FC addressing FICON protocol does not use the ALPA byte. However, the ALPA is a required byte in the FC address. The channel completes the FC address for a control unit link address by acquiring the ALPA that the switch returned to the channel when the channel logged in.

  • Page 40: Ficon And Ficon Cup In Virtual Fabrics

    FICON and FICON CUP in Virtual Fabrics FICON and FICON CUP in Virtual Fabrics For FICON CUP, FICON Management Server (FMS) mode is enabled on the logical switch and not the chassis. For example, in a Virtual Fabrics environment on the Brocade 6510 switch and the Brocade DCX Backbones, enable CUP on each logical switch.

  • Page 41: Addressing Modes

    Addressing modes • If addresses 0xFE or 0XFF have been assigned to physical ports, those ports must be disabled before FMS can be enabled. • For FICON CUP, FMS mode is enabled on the logical switch and not the chassis. For example, in a Virtual Fabrics environment on the Brocade 6510 switch and the Brocade DCX 8510-4 and DCX 8510-8 Backbones, you must set FMS mode independently on each logical switch.

  • Page 42: Mode 2 (Port-Based Addressing)

    Addressing modes NOTE Although port addresses are assigned when moved to a logical switch, the address is not bound to the port. To ensure that the link address for a control unit attached to a port does not change, the portAddress command must be used to bind the address to the port even if you are not changing the port address assignments.

    Troubleshooting FICON • Have you verified that your switch does not have a special mode setting turned on for FICON? NOTE There is no requirement to have a secure fabric in a switched point-to-point topology. Brocade Advanced features software package (Trunking, Fabric Watch, Extended Fabric) license activation is required.

    Supported Brocade blades The IP ports of an FX8-24 extension blade can operate with another FX8-24 or 7800. The maximum number of FX8-24 blades supported in a chassis it four. An FX8-24 can operate with an FX8-24E; however, IPSEC and compression is only supported on one 10G IP port on the FX8-24.
