Provide alerts (set by the user) on issues such as capacity problems and policy violations. Support chargebacks by usage or capacity 2.2 Product highlights This section describes significant features of IBM TotalStorage Productivity Center for Data Policy-based management IBM TotalStorage Productivity Center for Data can enable you to define and enforce storage policies through user-defined alerts, quotas, and constraints, notifying the user by e-mail, pager, or the event log, or a systems management console for events such as when a quota has been exceeded or a constraint violated. However, finding a problem is not enough. You need a way to fix problems -- or potential problems as they are discovered. IBM TotalStorage Productivity Center for Data can provide automated solutions through event management. For example, if IBM TotalStorage Productivity Center for Data discovers data that has not been accessed in more than a year, it can trigger Tivoli Storage Manager or another archive utility. Automatic file system extension IBM TotalStorage Productivity Center for Data's automated file system extension capability can allow the user to specify a policy to automatically extend a file system when a threshold has been reached. For example, if a file system's threshold is set at 78% and, through monitoring, IBM TotalStorage Productivity Center for Data identifies that this threshold has been exceeded, it can automatically initiate a file system extension to reduce the possibility of a storage-related outage. The feature supports both manual and automated initiated extension. Once you are comfortable with the manual process, you can turn over all the steps to IBM TotalStorage Productivity Center for Data. The policy is set through a File System Extension Policy Panel. A probe will run on agents and send file system statistics to the server. The server will compare the current file system state against the policy, and invoke provisioning and extension as necessary. Direct Tivoli Storage Manager integration With this feature, IBM TotalStorage Productivity Center for Data can automatically invoke Tivoli Storage Manager to archive and delete files. This can free up space in a file system and can allow you to more effectively manage storage utilization. For example, a policy can be created to archive all files over 365 days old to tape using IBM Tivoli Storage Manager, and then delete the files to free up the disk space. Subsystem reporting IBM TotalStorage Productivity Center for Data gathers and reports on disk subsystems. Information includes physical characteristics such as the drive's manufacturer, model, serial number, capacity, and rotational speed. Also included is how that drive's storage is allocated to logical volumes, snapshot copy volumes, and free space. This feature allows users to perform the following (subject to vendor's implementation of Storage Management Initiative Specification (SMIS)): Display the physical disks behind what the host sees as a disk drive Chapter 2.
