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.

Comments
This configuration can be any
mix of Metro Mirror and Global
Mirror relationships.
No additional limit is imposed
beyond the Remote Copy
relationships per clustered
system limit.
-
This limit is the total capacity for
all master and auxiliary
volumes in the I/O group.
-
-
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.

4096 for a full four node
clustered system with four I/O
groups.
