NOTE:
Universal Replicator for Mainframe can coexist with HP XP Continuous Access Journal in
the same storage system.
•
Remote copy connections − Fibre Channel (see
“Setting up Remote Copy Connections”
):
◦
Multimode or single-mode optical fibre cables are required at both the primary storage
system and secondary storage system.
◦
For distances up to 0.5 km, multimode optical shortwave fiber cables are required between
the primary storage system and secondary storage system.
◦
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 distance up to 10 km, single optical long wave fiber cables are required between
the primary storage system and secondary storage system.
◦
For distances from 10 km to 30 km (6.2 to 18.6 miles), single-mode long wave 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 Universal Replicator
for Mainframe solutions are provided based on user requirements and workload
characteristics.
•
Supported mainframe host operating systems (OS):
The XP disk array supports the following mainframe host operating systems (OS).
◦
MVS, OS/390, z/OS, VOS3, MSP-EX, z/Linux
◦
The optional error report communications (ERC) function requires MVS/DFP 3.2.0 or
later.
◦
If the primary and/or secondary systems consist of several CPU complexes, a SYSPLEX
timer is required to provide a common time reference for the host I/O time-stamping
function.
Because the z/Linux does not support a SYSPLEX timer, the I/Os from the z/Linux host do not
have the consistency. Therefore, you may not keep the consistency of the journal group. The
following figure illustrates the example.
