Supported Data Path Configurations - HP StorageWorks P9000 User Manual

For distances from 10 km to 30 km (6.2 to 18.6 miles), single-mode longwave Fibre Channel
interface cables with up to two switches are required.
For distances greater than 30 km. Approved third-party channel extender products and
telecommunications lines are required. Continuous Access Synchronous Z operations typically
do not extend past 30 km.
With Fibre Channel connections, you can use the switches as ordinary switch connections. No
special settings are required for the P9500.
Direct connections up to 10 km with single-mode longwave Fibre Channel interface cables are
supported. Link speed determines the maximum distance you can transfer data and still achieve
good performance. The following shows link speed and maximum distance for best performance.
