104 ILM Library: Techniques with Tivoli Storage and IBM TotalStorage Products
6.1 The big picture and why you should care about it
There has been much discussion around what ILM is. The best way to understand it is to
know where the ILM best practices fit in your IT environment. We give you an example of
such an IT infrastructure, as shown in the “big picture” in Figure 6-1 on page 105. This figure
represents a sample environment only. There are four main blocks represented by the large
boxes:
򐂰 Business, Consulting, Assessment, Definition
򐂰 Application, Server Hardware
򐂰 Software Infrastructure, Automation
򐂰 Hardware Infrastructure
We will show you on the following pages what components are part of each group and how
they interact. This will enable you to recognize where your current software and hardware fits.
This also gives you a starting point to implement ILM best practices, and to logically place
them in a new framework.
Finally, you see in Figure 6-1 on page 105 on the left side a description of the major
components. On the right side you see the orchestration tools.

6.1.1 Business consulting, assessment, definition
The aim of ILM best practices is to align information to business requirements through
management policies and service levels associated with applications, metadata, and data. If
your organization is large, has complex IT environments and distributed storage solutions,
the initial assessment can be quite challenging. IBM can work with you to define this baseline
or you can do it yourself. We provide some guidelines for this assessment in the following
chapters. During the assessment, you will identify the value, lifecycle, and classification of
information for each business unit. This collaboration requires not only input from IT service
management, but also from the business processes and business applications’ owners. This
