30 IBM Flex System V7000 Storage Node Introduction and Implementation Guide
1.6 Introduction to IBM Flex System storage
Either the IBM Storwize V7000 or IBM Flex System V7000 Storage Node is an integrated part
of the IBM PureFlex System, depending on the model. Figure 1-15 shows the IBM Flex
System V7000 Storage Node where the left controller, called a cannister, is taken out. For the
IBM Storwize V7000 products, the cannisters mount from the rear, whereas in the IBM Flex
System V7000 Storage Node, the controllers mount from the front.

The IBM Storwize V7000 product is described in detail in the Implementing the IBM Storwize
V7000 V6.3, SG24-7938.
For more information about the IBM Flex System V7000 Storage Node, see Chapter 2,
“Introduction to IBM Flex System V7000 Storage Node” on page 39.
1.6.1 IBM Storwize V7000 and IBM Flex System V7000 Storage Node
IBM Storwize V7000 and IBM Flex System V7000 Storage Node are virtualized storage
systems designed to complement virtualized server environments. They provide unmatched
performance, availability, advanced functions, and highly scalable capacity. IBM Storwize
V7000 and IBM Flex System V7000 Storage Node are powerful disk systems that have been
designed to be easy to use and enable rapid deployment without additional resources.
IBM Storwize V7000 and IBM Flex System V7000 Storage Node support block workloads,
whereas Storwize V7000 Unified (not covered in this book) consolidates block and file
workloads into a single storage system for simplicity of management and reduced cost.
IBM Storwize V7000 and IBM Flex System V7000 Storage Node support IBM Real-time
Compression™ for extraordinary efficiency, enabling storage of up to five times as much
active data in the same physical disk space

.
IBM Storwize V7000 and IBM Flex System V7000 Storage Node offer greater efficiency and
flexibility through built-in solid state drive (SSD) optimization and thin provisioning
technologies. IBM Storwize V7000 and IBM Flex System V7000 Storage Node advanced
functions also enable non-disruptive migration of data from existing storage, simplifying
implementation and minimizing disruption to users. Finally, these systems also enable you to
virtualize and reuse existing disk systems, supporting a greater potential return on investment
(ROI).
