DataStax Licensing – FAQs

DataStax software Subscriptions are sold on a per-Node or per-Core basis. Each Node may run on a maximum of 16 Cores:

• “Node” means a Java Virtual Machine (a platform-independent execution environment that converts Java bytecode into machine language and executes it) that runs an instance of the software
  
• “Core” means an independent physical processing unit on a CPU responsible for executing programs
  
• Virtualised CPUs do not count as Cores for these purposes and so a Node may have any number of virtualised CPUs provided that the physical CPUs do not exceed 16
  
• For DataStax Enterprise version 6.0 or higher, customers can use the system settings (tpc_cores:16) to comply with the above limitation.

If you have a DataStax Enterprise license you may:

• install and use DataStax Enterprise inside your organization
  
• install and use DataStax Enterprise on external servers that are hosted on your behalf (e.g. in AWS)
  
• take advantage of the free ‘bursting use’ benefit, enabling you to increase your DataStax Enterprise usage by 20% for up to two months in each 12 month period
  
• spin up dedicated DataStax Enterprise clusters to store OpsCenter storage metrics at no additional cost

You may not:

• have DSE clusters containing different types of DSE Subscription (i.e. all Nodes in each Cluster must be uniformly licensed to use the same level of DSE Subscription)
  
• incorporate DataStax Enterprise within a new software application that you distribute to other organizations
  
• use DataStax Enterprise to provide a database-as-a-service product made available to other organizations
  
• purchase DataStax Enterprise on behalf of someone else

The above examples are indicative and for guidance purposes only – please refer to the full DataStax licence terms available here.

Customers that have purchased DataStax Enterprise will receive a welcome guide and on-boarding documentation that detail how many Nodes of subscriptions they have purchased, along with any applicable restrictions.

You are responsible for ensuring that your usage of DataStax Enterprise complies with the quantity and type of licenses you have purchased. If you think you may exceed or have exceeded your licensed usage, you should take one of the following steps:

• identify any (additional) Nodes running DataStax Software and inform your DataStax relationship manager
  
• if this is not possible, request assistance from DataStax to enable you to run scanning tools to identify any (additional) Nodes running DataStax Enterprise within your organization.

Customers that are using free DataStax Software under the No-Fee Licence terms must comply with the relevant licence terms (please refer to question 4).

Please note that DataStax reserves the right to verify compliance, including by conducting audits on randomly selected users from time to time.
