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

2.6.2 IBM Flex System V7000 Remote Mirroring Software
The IBM Flex System V7000 Remote Mirroring provides both Metro and Global mirroring
capabilities between the IBM Flex System V7000 Storage Nodes, or between IBM Flex
System V7000 Storage Nodes and IBM Storwize V7000s or IBM SAN Volume Controllers
(SVC). This capability means customers have greater flexibility in their expanding
environments using Flex System V7000, Storwize V7000, and SVC with the ability now to
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 is multiplied. Remote deployments for disaster recovery for
current SVC and Storwize V7000 environments can easily be fitted with the Flex System
V7000 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
the 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).

With Metro Mirroring the IBM Flex System V7000 Remote Mirroring provides synchronous
data replication at distances less than 300Km. This capability is supported across either an
FC or FCoE SAN fabric infrastructure. Mirroring over iSCSI connections is not supported at
this time.

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.
