GLYPH<SM590000> Data reduction techniques for space efficiency, such as thin provisioning, Data Reduction  Pools (DRP), deduplication, and IBM Real-time Compression™ (RtC). Today, open  systems typically use less than 50% of the provisioned storage capacity. IBM Spectrum  Virtualize, can enable significant savings, increase effective capacity of storage systems  up to five times, and decrease the floor space, power, and cooling required by the storage  system. IBM Storwize V7000 is a scalable solution running on a highly available platform that can use  diverse back-end storage systems to provide all the benefits to various attached hosts. The storage virtualization functions of IBM Spectrum Virtualize are a powerful tool in the  hands of storage administrators. However, for an organization to fully realize benefits of  storage virtualization, its implementation must be the result of a process that begins with  identifying the organization’s goals. For a storage virtualization project to be a success, the  organization must identify what it wants to achieve before it starts to think how to implement  the solution. Today, organizations are searching for affordable and efficient ways to store, use, protect, and  manage their data. Additionally, a storage environment is required to have an easy to manage  interface and be sufficiently flexible to support wide range of applications, servers, and  mobility requirements. Although business demands change quickly, some recurring client  concerns drive adoption of storage virtualization, including the following examples: The importance of addressing the complexity of managing storage networks is clearly visible  in the results of industry analyses of the total cost of ownership (TCO) of storage networks.  Typically, storage costs are only about 20% of the TCO. Most of the remaining costs relate to  managing storage systems. In a non-virtualized storage environment, every system is an “island” that must be managed  separately. In large SAN environments, the sheer number of separate and different  management interfaces and lack of unified view of the whole environment jeopardizes an  organization’s ability to  manage their storage as a single entity and to maintain the current  view of the system state. IBM Storwize V7000, running IBM Spectrum Virtualize software, reduces the number of  separate environments that must be managed down to a single system. After the initial  configuration of the back-end storage subsystems, all of the day-to-day storage management  operations are performed by way of a single graphical user interface. At the same time,  administrators gain access to the rich functionality set provided by IBM Spectrum Virtualize,  whether particular features are natively available on the virtualized storage systems.
