2.2 IBM Flex System V7000 Storage Node terminology
The IBM Flex System V7000 Storage Node introduces some new terminology, which is
defined below in Table 2-1. We also include the terms first introduced with the IBM SVC and
the IBM Storwize V7000, and are important to understand the rest of the implementation
procedures discussed in this publication.
