Table 1 General system requirements (continued)
Requirement
Item
Supported RAID groups
•
RAID1, RAID5, and RAID6 are supported for both data and journal volumes.
•
RAID1, RAID5, and RAID6 can co-exist in the same journal.
Must be operable for primary and secondary systems to ensure pair creation
success. The secondary system cache must be configured to adequately support
Cache and nonvolatile storage
(NVS)
Cnt Ac-J Z remote-copy workloads, as well as local workload activity. In general,
increase cache capacity by 25 percent for Cnt Ac-J Z. Also, 1 GB should be added
for each journal on the system.
Note: When pair status is Pending, neither cache nor shared memory can be added
to or removed from the system. When either of these tasks is to be performed, first
split any pairs in Pending, status, then resynchronize when the cache or shared
memory operation is completed.
Required for disaster recovery.
Host failover software
Extended consistency groups
(EXCTGs)
•
A storage system can have a maximum of four EXCTGs.
•
An EXCTG can contain a maximum of 16 journals.
•
An EXCTG can contain journals from a maximum of four storage systems.
•
A journal can be registered in one EXCTG only.
RAID Manager consistency groups
when multiple primary and
secondary system
•
Up to four journals can be registered in one RAID Manager consistency group
number. If there are four systems, you must create one journal for each system.
•
Up to 8,192 pairs. You can register the total number of pairs in the journals
within one RAID Manager consistency group. However, it is recommended that
you register only up to 4,096 pairs.
Business Continuity Manager specifications
Pair operations can be performed using Business Continuity Manager (BCM) commands from the
host system to the storage system. With BCM commands, you can add, split, resynchronize, and
delete pairs, and monitor pair status. You can also create the Continuous Access Journal Z
association between primary and secondary system (add RCU).
For complete information, see the Business Continuity Manager User's Guide.
