License Model
Server/CAL
Server Licenses (per Instance)
For Products under the Server/CAL License Model, customer may use one Running Instance of server software in either a Physical OSE or Virtual OSE on a Licensed Server for each License it acquires.
Subscription licenses or licenses with active Software Assurance only. All CALs used to access the software under this model must also be acquired as subscription licenses or have active Software Assurance: When licensing by Virtual OSE, Customer may reassign any of its Licenses to any of its Licensed Servers located within the same Server Farm as often as needed. Customer may also reassign these Licenses from one Server Farm to another, but not on a short-term basis (i.e., not within 90 days of the last assignment).
Access Licenses
- Except as described here and noted in the Product-Specific License Terms, all server software access requires CALs or CAL Equivalent Licenses.
- CALs are not required for access by another Licensed Server.
