Planning Considerations for Fibre Channel Topologies 3 - All FICON devices must be included in the same zone to facilitate proper state change notification. This is achieved by creating a unique FICON zone or using the default zone. Disable the default zone and explicitly create a unique zone for all FICON devices. Regardless of the director or switch operating mode, FCP devices must be zoned in the traditional fashion, and FICON devices must be zoned to provide isolation from the FCP devices. All FICON devices must be included in the same zone to facilitate proper state change communication. - When establishing a zoning configuration, FICON devices must be assigned to director or switch port addresses that correspond to port HCD-assigned address definitions configured by the attached host. Associated FICON devices must be connected to the ports as configured. - Note the reciprocal nature of zoning configurations and PDCM arrays. When configuring zoning, all FICON devices are placed in one zone and FCP devices are zoned normally. When configuring definitions in a PDCM array, all FCP devices are configured to allow communication only with each other and FICON devices are configured normally. - FICON port addressing provides the ability to swap ports for maintenance. In general, swapping ports in intermix environments does not affect the practices described. However, if a user implements zoning using a Domain_ID and port numbers, zoning information must be updated contiguous with the port swap operation. Multiple Data Transmission Speeds in a Single Fabric The Sphereon 3232 Fabric Switch, Intrepid 6000-series Directors, and Sphereon 4000-series Fabric Switches support auto-sensing of 1.0625 and 2.1250 Gbps device connections. The Intrepid 10000 Director supports 1.0625, 2.1250, and 10.2000 Gbps device connections. The introduction of a higher data transmission speed to the SAN design provides several benefits and alternatives: • High-speed device connectivity - As Fibre Channel devices and HBAs evolve and become 10.2000 Gbps-capable, higher-speed switches are required to provide basic fabric connectivity.
