This IBM® Redbooks® publication gives a broad understanding of
storage clouds and the initial functionality that was introduced
for mainframes to have Transparent Cloud Tiering.
IBM DFSMS and the IBM DS8880 added functionality to provide elements of serverless data movement, and for IBM z/OS® to communicate with a storage cloud. They introduced the following key areas:
A gateway in the DS8880, which allows the movement of data to
and from Object Storage be using a network connection.
DFSMShsm enhancements to support Migrate and Recall functions to
and from the Object Storage. Other commands were enhanced to
monitor and report on the new functionality.
DFSMShsm uses the Web Enablement toolkit for z/OS to create and
access the metadata for specific clouds, containers, and
DFSMSdss enhancements to provide some basic backup and restore
functions to and from the cloud.
This IBM Redbooks publication is divided into the following parts:
Part 1 provides you with an introduction to clouds. You might be
new to clouds or have a confused view of cloud terminology. If so,
Part 1 is helpful in providing you with the basic knowledge you
Part 2 shows you how we set up the Transparent Cloud Tiering in
a controlled laboratory and how the new functions work. We provide
points to consider to help you set up your storage cloud and
integrate it into your operational environment.
Part 3 shows you how we used the new functionality to
communicate with the cloud and to send data and retrieve data from
