Teradata on VMware Developer Tier and Developer Tier Preconfigured

Developer Tier is a SUSE Linux Enterprise Server (SLES) operating system and Teradata Database packaged into a virtual container that runs in a VMware vSphere ESXI virtualized environment on third-party hardware. There are two variants of the Developer Tier including a Preconfigured version and the regular version.

Teradata Developer Tier (Preconfigured) is a simplified version of Teradata Database Developer Tier that allows you to deploy Teradata Database on VMware quickly and easily using the OVA template. Networking is already configured to use DHCP, and you can add storage to the system. The Preconfigured version enables you to deploy only the Database and the instructions are available in a separate user manual on this download page.

The full Developer Tier consists of an OVA file template and associated property files and scripts for deploying the Teradata Database and the associated Teradata ecosystem products. Once deployed by the VMware administrator, Developer Tier can be used to evaluate Teradata on VMware and the Teradata Database and the associated ecosystem products.


Note: You must have administrative privileges on the destination VMware environment to install and configure Developer Tier virtual machines.

Planning Extended Teradata System outages with Unity 15.10

Benjamin Franklin once observed " this world nothing can be said to be certain, except death and taxes". Planned down time can easily be added to that list. It's a certainty that any given IT system will require some planned down time to address security fixes, make configuration changes, or expand storage and compute capacity. Smart businesses always stay ahead of these demands, and promptly patch or upgrade their systems, but that often comes with a cost in down time.
