Part 1. Overview - IBM System storage DS6000 Series Redbook

Overview
Part 1
In Part 1 we describe the various Advanced Copy Services offerings for the IBM System
Storage DS6000 series and how they relate to previous Copy Services offerings that are
available on the Enterprise Storage Server® (ESS).
This part also shows how the existing Copy Services functions from the ESS can coexist with
the Copy Services for the DS6000 series. Similarly, we discuss their use with the DS8000
series Copy Services.
With the announcement of the DS6000 Series and of Advanced Copy Services for z/OS on
the DS6000 Series, we have introduced some new terminology. We also introduced these
terms for Advanced Copy Services Version 2 for the ESS. These terms are described in detail
in IBM System Storage DS6000 Series: Architecture and Implementation, SG24-6781, and
are summarized in Table 1.
