Analytical Ecosystem

The TVS Monitor portlet allows you to view statistics on data temperature and storage grade of cylinders allocated in Teradata Virtual Storage (TVS). Statistics reflect current relationships between data temperature and storage grade, and historical trends in the management of storage grades based on data temperature. This portlet is disabled by default and must be enabled using Portlet Library.

Temperature and grade metrics help assess storage requirements for your data, as well as fine tune the balance between disk performance and data-access demands. Suppose that statistics indicate an increasing proportion of hot data allocated to slow-grade storage. If fast storage is currently full, the Teradata System Administrator might consider upgrading to faster storage. If fast storage is not full, the Teradata System Administrator should verify that data migration and metrics collection have been enabled to ensure the slow migration of hot data over time.
