Scenario 3: There are three primary systems replicating to a central disaster recovery
system. The three primary systems are as follows:
A two-enclosure IBM Flex System V7000 Storage Node with nothing externally virtualized,
therefore it has two base system (IBM Storwize Family Software for Flex System V7000)
licenses.
A one-enclosure Flex System V7000 managing a DS5020 consisting of three enclosures,
therefore it has one base system (IBM Storwize Family Software for Flex System V7000)
license plus three IBM Flex System V7000 External Virtualization Software licenses.
A one-enclosure Flex System V7000 with nothing externally virtualized, therefore it has
one base system IBM Storwize Family Software for Flex System V7000 license.
The central disaster recovery system is a nine-enclosure Flex System V7000 with nothing
externally virtualized, therefore it has nine base system (IBM Storwize Family Software for
Flex System V7000) licenses.
The Flex System V7000 Remote Mirroring licensing would be as follows: a sum of seven
licenses for the primary systems plus seven licenses for the central disaster recovery system,
for a total of fourteen licenses required.
Real-time Compression
To authorize use of Real-time Compression capabilities of the IBM Flex System V7000, you
must purchase a license for IBM Flex System V7000 Storage Node.
Real-time Compression for each licensed enclosure managed by the IBM Flex System V7000
Storage Node, including each internal enclosure licensed with the IBM Flex System V7000
Base Software and each external enclosure licensed with the IBM Flex System V7000
External Virtualization Software.
For example, if you have IBM Flex System V7000 consisting of one control enclosure and one
expansion enclosures, managing a DS5020 consisting of four enclosures (four External
Virtualization licenses), in order to authorize Real-time Compression for this configuration,
you will need a license for the IBM Flex System V7000 Real-time Compression with a quantity
of six enclosure authorization features.
