Frequently Asked Questions

1. What is a TCore?

TCore is our metric to provide a constant consumption metric across the hybrid cloud deployment options. This allows for license portability as well as some pricing consistency as customers move their Teradata Database license between platforms.

The metric is derived by combining both the CPU core count and the I/O bandwidth to each core. Simply, if you have enough I/O bandwidth to keep a core completely busy then you have a higher TCore rating. If your bandwidth can only provide enough data to keep a core 50% then you’d have a lower TCore rating.

The reasoning for this is that traditional licensing of either a “node” or other CPU metric is not an adequate measure for how effectively you can utilize the Teradata Database. In a similar manner, only looking at the size of the data (TB or PB) or the amount of I/O is again not a realistic measure of utilization. You must have both sufficient CPU to provide the processing power and sufficient I/O to keep the processors busy in order to get maximum effectiveness.

Clearly you want to size configurations in a balanced manner but that is not always the case, especially as you look across all the deployment options of the hybrid cloud.

For those detailed oriented folks: the actual calculation is:

(Cores / 5) + (System I/O / 437.5)

Using this formula, let’s look at two different systems. They both have 16 cores but one is a High IO IntelliFlex system with 5610 MB/Sec and the other is a balanced system with 4680 MB/Sec. This would give us 16 Tcore for the High IO system (16/5 + 5610/437.5) and 13.9 TCore (16/5 + 4680/437.5) for the balanced system

2. I am an existing customer, how does this affect me?

Current customers should work with their account teams to understand the migration from their existing perpetual based licenses to our new subscription based licensing. There are migration credits available based on their current software package and platform configurations.

3. Can I get the new bundling of database features under the perpetual license?

No, the bundling of the database features is under the subscription model. This is one of the many advantages that may provide the impetus to move from perpetual to subscription licenses.

4. What are the concurrency limits for each tier?

The tiers were created to allow the best fit for workload profiles. The developer tier is limited to 2 nodes and 2 concurrent queries. The idea is that this is basic development of testing of features.

The base tier has a 128 node and 15 concurrent query limit. This tier is targeted to entry level system or possibly departmental systems. Another scenario is a customer would have a production system with an advanced or enterprise license and then have a DR or development system with a base license. This provides for all the functionality with lower costs on the development platforms.

The advanced and enterprise tiers have no limit to the number of concurrent queries.

5. Why the limited workload management and memory features between the tiers?

Due to the limit of concurrent queries or the platform of deployment, not all features make sense at all tiers. For example, as developer only have 2 concurrent queries, it would not make sense to have workload management or memory optimizations as they are features that are leveraged in large, mixed workload environments.

As for the difference between advanced and enterprise it is a matter of degree. Not all customers need the leading edge active system management available in TASM. The advanced tier allows for a large, complex user community but at a lower cost than enterprise. When a customer evolves to the point where such capabilities are necessary, it is simply a licensing issue whereas in the past TASM was not offered on the 2800 system.

6. Are there any other bundled features?

Yes. The chart was not an exhaustive listing but highlighted some previously charged for features that are now included. Other bundled features includeviewpoint and ecosystem manager (both for a single system), REST services, Data Stream Utility (DSU), TTU, and TPT Streaming / TPump data loading tool.

7. So what is not bundled but still sold as separate licensing?

Features that would be licensed separately are those features that require more than one Database instance to operate. These are items such as the Viewpoint for multiple systems, Data Lab portlet, Data Mover, Unity and QueryGrid. These features are not available on the Developer tier

8. Why isn’t developer tier offered on IntelliCloud, IntelliBase or IntelliFlex?

This is a matter of applicability. The developer tier is a free license with limited scale and concurrency. It would not make any sense for someone to buy a physical platform, or enter into a contract for IntelliCloud and then ONLY have the Developer Tier with the limitations.

9. Does Subscription Based Pricing cost more over time?

No it does not. When you look at the payments patterns between perpetual and subscription based over time you see that the payments tend to equal out. The benefit of Subscription-Based licensing is less up front commitment of cash  and new benefits, such as bundles and portability, which are not available with the Perpetual license model.

10. Will Subscription-Based prices increase over time?

While we cannot guarantee that prices will not increase, the history of the Teradata database license has been to decrease prices over time. The few instances where the price increased it were associated with significant new database features.

For customers that want to preserve their pricing they can enter into a 3 year commitment for subscription period.

11. What support comes with the Subscription-Based license?

All tiers come with premier support included. Customers wanting to upgrade to Business Critical support or add additional services may do so.

12. Are database software upgrades included with the license?

Yes. This is another significant difference and benefit of the new licensing model. Customer will now have access to software updates throughout the subscription period. You should encourage your customer to stay current with our software to leverage all the benefits and features as we incorporate them into the database.
