32 IBM Flex System V7000 Storage Node Introduction and Implementation Guide
user interface (GUI). Together, these technologies are designed to 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 immediately as data 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, 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 may help avoid penalties and
additional maintenance charges for lease extensions. The result can be real cost savings to
your business.
Foundation for cloud deployments
Improving efficiency and delivering a flexible, responsive IT infrastructure are essential
requirements for any cloud deployment. Key technologies for delivering this infrastructure
include virtualization, consolidation and automation.
With their virtualized storage design and tight affinity with technologies such as IBM
PowerVM, and VMware, IBM Storwize V7000, IBM Flex System V7000 Storage Node, and
IBM Storwize V7000 Unified are the ideal complement for virtualized servers that are at the
heart of cloud deployments. IBM Storwize V7000 and IBM Flex System V7000 Storage Node
help enable consolidation of multiple storage systems for greater efficiency. With IBM
Storwize V7000 and IBM Flex System V7000 Storage Node, clustered systems drive the
value of consolidation even further, and IBM Real-time Compression helps improve cost
