2.7.4 Copy Services configuration limits
In Table 2-10, we describe the Copy Services configuration limits. For the most up-to-date list
of these limits, see the following website:

2.8 Management and support tools
The IBM Flex System V7000 Storage Node system can be managed through the IBM Flex
System Management Node (FSM), or by using the native management software that runs in
the hardware itself.
The FSM simplifies storage management in the following ways:
򐂰 Centralizes the management of storage network resources with IBM storage
management software.

Remote Copy (Metro Mirror and
Global Mirror) relationships per
clustered system 4096 This configuration can be any
mix of Metro Mirror and Global
Mirror relationships.
Remote Copy relationships per
consistency group 4096 No additional limit is imposed
beyond the Remote Copy
relationships per clustered
system limit.
Remote Copy consistency
groups per clustered system 256 -
Total Metro Mirror and Global
Mirror volume capacity per I/O
group 1024 TB This limit is the total capacity for
all master and auxiliary
volumes in the I/O group.
FlashCopy mappings per
clustered system 4096 -
FlashCopy targets per source 256 -
Cascaded Incremental
FlashCopy maps 4 A volume can be the source of
up to four incremental
FlashCopy maps. If this number
of maps is exceeded, then the
FlashCopy behavior for that
cascade becomes
non-incremental.
