Licensing Models
System Center 2025 employs a dual licensing approach that addresses both server and client management needs. This model aligns with Windows Server licensing to provide consistency and simplify license management for organizations using both products.
Server Management Licenses (Server MLs)
Server Management Licenses follow a core-based model that scales with the computing capacity of the managed infrastructure. This approach ensures that licensing accurately reflects the resources being managed.
| Aspect | Details | Additional Information |
|---|---|---|
| Licensing Metric | Physical cores in the server | All physical cores must be licensed |
| Minimum Requirements | 8 cores per processor, 16 cores per server | Even if actual core count is lower |
| License Packaging | Sold in packs of two cores | Minimum 8 packs per server |
| Standard Edition Rights | 2 OSEs per license (stack for more) | For every 2 additional VMs, all cores must be licensed again |
| Datacenter Edition Rights | Unlimited OSEs per license | No additional licensing regardless of VM count |
The core-based licensing model provides a consistent approach that aligns with modern datacenter architecture. By focusing on physical cores rather than processors, the model scales appropriately with varying server configurations and capabilities.
For organizations transitioning from previous versions with Software Assurance, core grants ensure that existing virtualization rights are maintained during the migration to the core-based model.
Client Management Licenses (Client MLs)
Client Management Licenses address the management of non-server devices such as desktops, laptops, and mobile devices. The flexible options allow organizations to choose the most cost-effective approach based on their specific environment.
| License Type | Coverage | Best For |
|---|---|---|
| Per User ML | Any OSE accessed by one user | Environments where users access multiple devices |
| Per OSE ML | One OSE accessed by any user | Shared device scenarios (kiosks, shift workers) |
| Device ML | Any OSE on one device | Organizations standardized on device-based licensing |
Client management licensing provides the flexibility needed to accommodate various organizational structures and device usage patterns. Organizations can select the model that best aligns with their environment, or even mix models to optimize licensing costs across different scenarios.
Core Licensing Requirements
Understanding the specific requirements for core-based licensing is essential for ensuring compliance and optimizing costs. System Center 2025 follows clear rules regarding core counting and licensing minimums.
| Requirement | Description | Implementation Details |
|---|---|---|
| Core Coverage | All physical cores must be licensed | Count all cores across all processors in each managed server |
| Minimum Licensing | 8 cores per processor, 16 cores per server | Apply these minimums even if actual core count is lower |
| Purchase Units | 2-core packs (minimum 8 packs per server) | Calculate total packs needed based on core count and minimums |
| Standard Edition Stacking | For every 2 additional VMs beyond initial 2, all cores must be licensed again | Example: 6 VMs requires 3 sets of Standard licenses |
| Datacenter Edition | No additional licenses needed regardless of VM count | Simplifies management for highly virtualized environments |
The core licensing model includes provisions for various server configurations, ensuring that licensing scales appropriately with the computing capacity being managed. Organizations should carefully inventory their server infrastructure to determine the total core count and apply the appropriate minimums when calculating license requirements.
Licensing Scenarios
Different IT environments require different licensing approaches. Understanding how System Center 2025 licensing applies to various scenarios helps organizations make informed decisions about their licensing strategy.
Scenario Comparison
