Continuous Access Synchronous connections.
Supported data path configurations
Three Fibre Channel configurations are supported for Continuous Access Synchronous. LUN
Manager is used to set port topology.
• Direct connection—two devices are connected directly together, shown below.
Figure 6 Direct connection
Set port topology to: Fab off, FC-AL.
• Switch connection—up to three optical fibre cables are connected using switches. Up to two
switches can be used, as shown below.
Figure 7 Switch connection
Set port topology to the following:
NL port: Fab on, FC-AL
N port: Fab on, Point-to-Point
Some switch vendors require F port (for example, McData ED5000).
• Extender connection—channel extenders and switches are used to connect the devices across
large distances, as shown below.
