Most clients aim to integrate the FlashCopy feature for point in time copies and quick recovery
of their applications and databases. IBM Support is provided by Tivoli Storage FlashCopy
Manager, which is described at the following website:
http://www-01.ibm.com/software/tivoli/products/storage-flashcopy-mgr/
You can read a detailed description about the FlashCopy copy services in 9.2, "FlashCopy" on
page 364.

2.7.2 IBM Flex System V7000 Remote Mirroring software

The IBM Flex System V7000 Remote Mirroring software provides both Metro and Global
mirroring capabilities between IBM Flex System V7000 Storage Nodes, or between IBM Flex
System V7000 Storage Nodes and IBM Storwize V7000s or IBM SAN Volume Controllers
(SVCs). This capability means that customers have greater flexibility in their expanding
environments using IBM Flex System V7000 Storage Node, Storwize V7000, and SVC, with
the ability now to perform remote mirror from one system to the other.
With the wide variety of storage systems that can be managed under any of these systems,
the options available for replicating data between a number of storage systems are multiplied.
Remote deployments for disaster recovery for current SVC and Storwize V7000 environments
can easily be fitted with IBM Flex System V7000 Storage Node or vice versa.
The Copy Services layer sits above and operates independently of the function or
characteristics of the underlying disk subsystems used to provide the storage resources to
IBM Flex System V7000 Storage Node. Figure 2-19 shows an example of possible copy
service relationships (they must be at Version 6.4 or later).
Figure 2-19 Example of possible copy services relationships
With Metro Mirroring, IBM Flex System V7000 Remote Mirroring provides synchronous data
replication at distances less than 300 Km. This capability is supported across either an FC or
FCoE/FC SAN fabric infrastructure. Mirroring over iSCSI connections is not currently
supported.
Global Mirroring provides for long distances of greater than 300 Km and is only supported
over an FC SAN infrastructure. Tunneling over a WAN network is frequently used for the
greater distance needs.
