32 IBM Flex System V7000 Storage Node Introduction and Implementation Guide
With an online database workload, Easy Tier improved throughput up to 200 percent and
reduced transaction response time by up to 30 percent compared to a configuration using
only HDD.

Extraordinary storage efficiency
IBM Storwize V7000 and IBM Flex System V7000 Storage Node combine a variety of IBM
technologies including thin provisioning, automated tiering, storage virtualization, Real-time
Compression, clustering, replication, multi-protocol support, and a next-generation graphical
user interface (GUI). Together, these technologies enable IBM Storwize V7000 and IBM Flex
System V7000 Storage Node to deliver extraordinary levels of storage efficiency.
Newest of these technologies is IBM Real-time Compression, which is designed to improve
efficiency by compressing data as much as 80 percent, enabling you to store up to five times
as much data in the same physical disk space. Unlike other approaches to compression, IBM
Real-time Compression is designed to be used with active primary data such as production
databases and e-mail applications, which dramatically expands the range of candidate data
that can benefit from compression. As its name implies, IBM Real-time Compression
operates in real time, meaning that host write is compressed as it passes through the
compression software that is part of the SVC and IBM Flex System V7000 software stack
before it is written to disk, so no space is wasted storing uncompressed data awaiting
post-processing.
The benefits of using IBM Real-time Compression together with other efficiency technologies
are very significant and include reduced acquisition cost (because less hardware is required),
reduced rack space, and lower power and cooling costs throughout the lifetime of the system.
When combined with external storage virtualization, IBM Real-time Compression can
significantly enhance the usable capacity of your existing storage systems, extending their
useful life even further.
IBM Real-time Compression is available for IBM Storwize V7000 and IBM Flex System V7000
Storage Node.
Avoiding disruptions with dynamic migration
IBM Storwize V7000 and IBM Flex System V7000 Storage Node use virtualization technology
to help insulate host applications from physical storage changes. This ability can help enable
applications to run without disruption while you make changes to your storage infrastructure.
Your applications keep running so you can stay open for business.
Moving data is one of the most common causes of planned downtime. IBM Storwize V7000
and IBM Flex System V7000 Storage Node include a dynamic data migration function that is
designed to move data from existing block storage into the new system or between arrays in a
IBM Storwize V7000 and IBM Flex System V7000 Storage Node, while maintaining access to
the data. The data migration function might be used, for example, when replacing older
storage with newer storage, as part of load balancing work or when moving data in a tiered
storage infrastructure.
Using the dynamic migration capabilities can provide efficiency and business value. Dynamic
migration can speed time-to-value from weeks or months to days, minimize downtime for
migration, eliminate the cost of add-on migration tools, and can help avoid penalties and
additional maintenance charges for lease extensions. The result can be real cost savings to
your business.
