Chapter 14. Copy Services for the DS6000
In this chapter, we describe the implementation of Copy Services for the DS6000 from a
performance enhancing viewpoint. Copy Services is a collection of functions provided by the
DS6000 that provide Disaster Recovery, data migration, and data duplication functions. Copy
Services are optional features that run on the DS6000 server enclosure and they support
open systems and zSeries environments.
Copy Services has four interfaces; a Java-enabled Web-based interface (DS Storage
Manager), a command-line interface (DS CLI), an application programming interface (DS
Open API), and host I/O commands from zSeries servers.
This chapter discusses the functions, objectives, and performance related aspects of the
following Copy Services:
