HP XP P9000 Continuous Access Synchronous for Mainframe Systems User Guide

data is collected using performance monitoring software. Consult your HP account team for more
information.
Fibre Channel requirements
The main and remote system must be connected using multi-mode or single-mode optical fibre
cables.
• For distances between .5 km to 1.5 km, one switch is required, but you can use a maximum
of two switches.
• For distances up to 1.5 km (4,920 feet), multimode shortwave Fibre Channel interface cables
are used.
• For distances from 1.5 km to 10 km, (4,920 feet to 6.2 miles) single mode longwave optical
fibre cables are required.
• 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. Cnt Ac-S 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 XP 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 table shows maximum distances at which performance is
maintained per link speed, over single-mode longwave Fibre Channel.

Your HP account team can provide the latest information about the availability of serial-channel
Cnt Ac-S Z connections.
Supported data path configurations
Three Fibre Channel configurations are supported for Cnt Ac-S Z:
• “Direct connection” (page 47)
• “Switch connection” (page 48)
• “Extender connection” (page 48)
Direct connection
The following figure shows a direct connection, in which two devices are connected directly
together.
