System requirements
XP Continuous Access Journal operations involve primary and secondary arrays containing the
primary and secondary volumes, remote copy connections between primary and secondary arrays,
hosts at the primary and remote sites, and the licensed XP Continuous Access Journal. XP Continuous
Access Journal system requirements are:
•
Primary array: local array with XP Continuous Access Journal installed
•
Secondary array: local array with XP Continuous Access Journal installed
NOTE:
XP Continuous Access Journal can coexist with Hitachi Universal Replicator for z/OS
in the same local array.
•
Remote copy connections: Fibre Channel (see
)
Multimode or single-mode optical fibre cables are required at the primary and secondary
arrays.
◦
◦
For distances up to 0.5 km, multimode optical shortwave fiber cables are required between
the primary and secondary arrays.
◦
For distances from 0.5 km to 1.5 km (1,640 to 4,920 feet), multimode shortwave Fibre
Channel interface cables with up to two switches are required.
◦
For distances up to 10 km, single optical longwave fiber cables are required between
the primary and secondary arrays.
◦
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 (18.6 miles), approved third-party channel extender
products and telecommunications lines are required. Long-distance XP Continuous Access
Journal solutions are provided based on user requirements and workload characteristics.
