Severity 1 (emergency): the failure has a serious impact on your use of software in a production environment (such as loss of production data or failure of the production system). Your production cannot continue in this case, and there is no temporary solution.

Serious sector 2 (high): the production environment is partially affected, the processing capacity is seriously reduced, affecting some business operations, and there is no temporary solution.

Severity level 3 (medium): non-critical businesses in the production or development environment are affected, affecting the business system, but business operations can continue to operate. Or you can use a temporary method to keep the business operation going. For the development environment, the failure prevents you from importing or migrating the development results to the production environment.

Severity level 4 (low): common usage questions, either errors in documentation, or suggestions for future product features. For the production system, the impact is small or zero. For the development environment, the impact is moderate to low, and the business can continue to run.

Subscribe to packaging model physical CPU pairs and virtual machine pairs

Physical CPU pair: 2 physical CPU

Virtual machine pair: 2 virtual machine instances

Users can be based on physical or virtualization. If the RED HAT is deployed to the physical machine, the number of subscriptions is based on the physical CPU pair of the installation system; if the RED HAT is deployed to the virtualized environment, the subscribed data is based on the virtual machine pair. This model is suitable for low-to medium-density virtualized environments.

The subscription types that apply to this model include:

Red Hat Enterprise Linux Server.

Red Hat Enterprise Linux Server Entry Level, Self-support.

Red Hat Enterprise Linux Add-Ons.

Unlimited number of virtual machine licen

Subscriptions to this model are based on physical CPU pairs. With this type of subscription, users can run an unlimited number of virtual instances on the physical host. The model is suitable for high-density virtualized environment. The subscription types that are appropriate for this model include:

Red Hat Cloud Infrastructure.

Red Hat OpenStack ®Platform.

Red Hat Enterprise Linux for Virtual Datacenters.

Red Hat Enterprise Linux Add-Ons.

Subscription merge

When your system has more than one physical CPU pair or virtual machine pair, you can calculate the number of subscriptions you need according to the multiple of CPU pair or virtual machine pair. For example, if you have an 8-way server, the number of subscriptions you need to buy is 8-way, 2-way, 4-way.

Subscription reuse

You can exchange subscriptions between physical hosts and virtual machines. For example:

If you have a free subscription for 2CPU on hand, you happen to need 2 virtual machines, which are used in 2 virtual machine environments. And vice versa.
