3 Preparing for XP Continuous Access operations
System requirements
XP Continuous Access operations involve MCUs and RCUs containing primary and secondary
volumes, remote copy connections between MCUs and RCUs, UNIX and/or PC server hosts at
primary and remote sites, and XP Continuous Access. You can use the XP Command View Advanced
Edition management station or XP Remote Web Console to manage MCUs and RCUs. XP Continuous
Access system requirements are:
•
MCU: Disk array with XP Continuous Access installed.
•
RCU: Disk array with XP Continuous Access installed.
•
UNIX-based and/or PC server platforms: The disk array supports XP Continuous Access
operations for a variety of UNIX and PC-server platforms, including the Sun Solaris, IBM AIX,
HP-UX, and Windows NT platforms. Contact your HP account support representative for the
latest information on array platform support for XP Continuous Access.
•
Remote copy connections – Fibre Channel:
Multimode optical fibre cables at both the MCU and RCU ◦
◦ For distances from 0.5 km to 1.5 km (1640 to 4920 feet), multimode shortwave Fibre
Channel interface cables with up to two switches are required (tor 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 (or DWDM)
products and telecommunications lines
NOTE: All Fibre Channel remote copy activities between two XP or SVS 200 subsystems
(for example, XP Continuous Access Sync and Async, remote replication for z/OS Sync
and Async) can share the same remote copy connections.
•
XP Command View Advanced Edition management station or XP Remote Web Console:
Web-based GUI for XP Continuous Access and license keys. You can access XP Remote Web
Console directly from the disk array or through XP Command View Advanced Edition.
•
About the license of HP StorageWorks XP Continuous Access Asynchronous: If you want to
use HP StorageWorks XP Continuous Access Asynchronous, you must install not only a license
for HP StorageWorks XP Continuous Access Asynchronous but also a license for HP
StorageWorks XP Continuous Access. Also, the license capacity of HP StorageWorks XP
Continuous Access and the license capacity of HP StorageWorks XP Continuous Access
Asynchronous must satisfy the following equation: License capacity of HP StorageWorks XP
Continuous Access
License capacity of HP StorageWorks XP Continuous Access
Asynchronous.
NOTE: You must operate XP Command View Advanced Edition or XP Remote Web Console in
Modify mode to perform XP Continuous Access operations. In view mode, you can only view XP
Continuous Access information.
Requirements and restrictions
