Top customer problems/requirements eRMM Solution<br />
No centralized access control, administration <strong>and</strong><br />
reporting<br />
<strong>IBM</strong>’s eRMM provides a middleware between heterogeneous applications <strong>and</strong><br />
library hardware to build a very flexible <strong>and</strong> scalable infrastructure (see<br />
Figure 1-8). It provides centralized management functions like cross library<br />
cartridge pooling, cross library drive pooling, cross application drive sharing,<br />
mount request queuing, centralized access control <strong>and</strong> auditing, <strong>and</strong> advanced<br />
reporting functions.<br />

Provide centralized access control, administration<br />
<strong>and</strong> reporting accessible through open st<strong>and</strong>ards<br />
based API (IEEE1244) <strong>and</strong> SSG Console WUI<br />
No integrated support <strong>for</strong> vaulting Provide integrated support <strong>for</strong> manually operated<br />
libraries <strong>and</strong> vaults together with policy-based<br />
cartridge life cycle management (planned <strong>for</strong> future<br />
release)<br />
Adding storage or upgrading storage technology<br />
requires changes to every application<br />
Eliminate changes when storage is added <strong>and</strong><br />
minimize impact of technology upgrades<br />

To achieve this functionality, eRMM consists of the following major components:<br />
► <strong>Media</strong> Manager (MM)<br />
This is the central “server” component which among other tasks coordinates<br />
access to drives <strong>and</strong> cartridges, h<strong>and</strong>les volume allocation <strong>and</strong> deallocation<br />
requests, <strong>and</strong> stores a log of all activities persistently <strong>for</strong> auditability. MM<br />
utilizes a dedicated instance of <strong>IBM</strong> DB2® <strong>for</strong> persistent storage.<br />
