Planning Considerations for Fibre Channel Topologies

Planning Considerations for Fibre Channel Topologies

— 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,

2.1250, and 4.2500 Gbps device connections. The Intrepid 10000

Director supports 1.0625, 2.1250, and 10.2000 Gbps 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.
