Exploring Storage Management Efficiencies and Provisioning - Understanding IBM TotalStorage Productivity Center and IBM TotalStorage Productivity Center with Advanced Provisioning

Chapter 2. Architecture 21

IBM TotalStorage Productivity Center with Advanced Provisioning (bringing

together IBM Tivoli SAN Manager and IBM TotalStorage Multiple Device

Manager and IBM Tivoli Provisioning Manager) can create your additional

storage “on-demand” and provide access to that storage to your applications and

servers through your storage area network, while IBM Tivoli Storage Resource

Manager will monitor this storage, notify you of any alerts, and take any other

automated actions you define.

2.4 Communications

For the integration with IBM Tivoli Provisioning Manager to work, some

Application Program Interfaces (APIs) to IBM TotalStorage Multiple Device

Manager and IBM Tivoli SAN Manager have been added. A Web service model

is used which matches the IBM direction of Services Oriented Architecture

(SOA).

And as we continue to manage components of the environment, we want to

provide those interfaces so there is a central place to go, if, for example, you

decide that you need more storage for your WebSphere application. WebSphere

can use these interfaces to interact with IBM TotalStorage Productivity Center.

An enablement layer has been added that is delivered with IBM Tivoli SAN

Manager. This enablement layer is installed with the IBM Tivoli SAN Manager

and IBM TotalStorage Multiple Device Manager WebSphere component and

serves as the interaction point between the IBM Tivoli Provisioning Manager

workflow engine and IBM TotalStorage Productivity Center (see Figure 2-3).

IBM TotalStorage Productivity Center Integration Layer provides an integrated

interface to the functions provided by IBM TotalStorage Multiple Device Manager

(disk manager) and IBM Tivoli SAN Manager (fabric manager). The IBM

TotalStorage Productivity Center Integration Layer provides a set of basic

function actions and associated IBM Tivoli Provisioning Manager workflows.

These actions are implemented as Java plug-ins. The information is exchanged

by following Simple Object Access Protocol (SOAP) specifications and using

XML. The plug-ins are combined into IBM Tivoli Provisioning Manager

workflows. Workflows are built from a combination of one or more of these Java

Plug-Ins and other processing steps. This allows the power of the IBM Tivoli

Provisioning Manager workflow engine to exploit the basic storage function

actions provided by IBM TotalStorage Productivity Center.
