The Storwize V7000 storage capabilities can be expanded with optional licensed functions. Each optional
Storwize V7000 software license is required for each controller unit, expansion unit, and externally
virtualized storage units.
The following optional licensed functions are available:
Easy Tier
Easy Tier provides a mechanism to seamlessly migrate frequently accessed data between three tiers
of storage (Flash drives, SAS, and NL SAS). This migration can be to different tiers of internal drives
or to external storage systems that are virtualized by Storwize V7000.
FlashCopy
FlashCopy enables creating copies of data for backup, parallel processing, testing, and
development and have the copies available almost immediately. Storwize V7000 supports up to
2,048 FlashCopy targets per system and up to 8,192 FlashCopy targets per four-system cluster.
Real-time Compression
Real-time Compression enables storing up to five times as much data in the same physical disk
space by compressing data as much as 80% (based on IBM lab measurements). Real-time
Compression uses hardware acceleration. It is designed to be used with active primary data, such
as production databases and email systems, which dramatically expands the range of candidate
data that can benefit from compression. Real-time Compression operates immediately as data is
written to disk, meaning that no space is wasted storing uncompressed data awaiting post-
processing.
Encryption
This feature provides encryption for data at rest for enhanced data security. Encryption is performed
by the Storwize V7000 control enclosure for data that is stored within the Storwize V7000 system
(the control enclosure and all attached expansion enclosures) and externally virtualized storage
capacities. Encryption feature does not require self-encrypting drives (SEDs); it works with
traditional drives. Encryption is enabled on the entire Storwize V7000 system (Storwize control
enclosure and all attached Storwize V7000 expansion enclosures) and externally virtualized storage
under its control.
Remote mirroring
This feature provides storage system-based data replication by using synchronous or asynchronous
data transfers over IP, FC, or FCoE communication links. The following mirroring options are
available:
Metro Mirror maintains a fully synchronized copy at metropolitan distances (up to 300 km)
Global Mirror operates asynchronously and helps maintain a copy at greater distances (up to
8000 km
For ultimate flexibility, Storwize V7000 remote mirroring interoperates with any other Storwize family
system, including Storwize V5000, Storwize V3700, and SAN Volume Controller.
The remote mirroring licenses must be acquired for the primary (local) and secondary (remote)
systems. If Storwize V7000 is mirrored to a system other than Storwize V7000, the other system
must have the appropriate and applicable licenses for remote mirroring.
External Virtualization
This feature helps consolidate storage systems from various vendors that are connected into single
FC networking. Storage administrator can manage and provision storage to applications from a
single user interface and use a common set of advanced functions across all the storage systems
under the control of Storwize V7000.
