The System Center suite includes several core components to meet specific infrastructure management needs, such as monitoring, data protection, virtualization, and service management.
Here are the key components of the System Center:
- The System Center Operations Manager (SCOM) monitors the IT infrastructure’s health, performance, and availability.
- System Center Configuration Manager (SCCM): Facilitates deploying, managing, and securing devices and applications across an organization.
- System Center Virtual Machine Manager (SCVMM): Helps manage virtualized environments, including Hyper-V, VMware, and Citrix XenServer.
- System Center Data Protection Manager (DPM): Provides backup and recovery solutions for Microsoft workloads.
- System Center Orchestrator: Used to automate and integrate IT processes.
- System Center Service Manager (SCSM): Offers IT service management capabilities, including incident and change management.
Licensing System Center effectively depends on understanding the type of infrastructure you need to manage and the different licensing models available.
2. System Center Licensing Models
Microsoft System Center is licensed primarily in Server Management Licenses (SMLs) and Client Management Licenses (CMLs). Each license type has specific use cases, and choosing the right one depends on the infrastructure setup and management needs.
2.1 Server Management Licenses (SMLs)
Server Management Licenses are required to manage servers using the System Center. These licenses come in two main editions:
- System Center Standard Edition: Suitable for managing non-virtualized or lightly virtualized environments. The Standard Edition is designed for servers with limited virtualization needs, allowing for managing up to two virtual machines (VMs) per licensed server.
- System Center Datacenter Edition: Ideal for managing highly virtualized or cloud-based environments. Datacenter Edition allows unlimited virtualization, meaning you can manage unlimited VMs on the licensed server. This edition is best suited for enterprises with extensive virtualization requirements.
The licensing of System Center is closely aligned with Windows Server Licensing and follows a core-based model:
- Core-Based Licensing: Standard and center editions require you to license all physical cores on a server, with a minimum of 16 licenses per server, regardless of the actual number of cores. Core licenses are sold in packs of two.
- Virtual Machines: Each licensed server covers up to two VMs for the Standard Edition. If you need to manage more VMs, additional licenses are required. For the Datacenter Edition, licensing all physical cores allows you to manage unlimited VMs on that server.
2.2 Client Management Licenses (CMLs)
Client Management Licenses are required to manage client devices (such as desktops, laptops, and mobile devices) with System Center Configuration Manager (SCCM) or other System Center tools. CMLs are available in two types:
Device CML: Licenses a single device, regardless of how many users access it. This is more suitable for shared devices or kiosks where multiple users access the same device.
User CML: Licenses a specific user to manage multiple devices. This is ideal if users have multiple devices they need to manage.
3. Key Considerations for Choosing Between Standard and Datacenter Editions
Choosing between System Center Standard and Datacenter Editions largely depends on the level of virtualization your organization requires:
- Virtualization Needs: If your server environment is largely virtualized, with multiple virtual machines on each host, the Datacenter Edition is likely the most cost-effective choice. Licensing the physical cores with Datacenter Edition allows unlimited VM management, making it highly suitable for environments that host multiple workloads.
- Low Virtualization or Physical Servers: The Standard Edition is a better choice for environments that do not rely heavily on virtualization or primarily use physical servers. It provides sufficient management capability for up to two VMs per licensed server.
- Cost-Effectiveness: System Center Datacenter Edition may have a higher initial cost. However, its ability to manage unlimited VMs per host makes it cost-effective in environments with many virtual servers. In contrast, Standard Edition can become costly if you manage many VMs, as additional licenses are required for each additional set of two VMs.
4. Components and Capabilities Covered by System Center Licensing
When licensing Microsoft System Center, it’s important to understand the components and capabilities included under each edition. A System Center license allows you to manage the following aspects of your IT infrastructure:
Configuration Management: With SCCM, you can deploy software, patches, and configurations to servers and client devices. SCCM offers remote control, inventory management, and operating system deployment capabilities, whereas the Standard Edition will require numerous additional licenses.
Virtual Machine Management: SCVMM allows you to manage VMs across different platforms, including Hyper-V, VMware, and Citrix XenServer. The Datacenter Edition offers unlimited virtualization rights, allowing for comprehensive VM management across all hosts.
Monitoring and Automation: SCOM helps monitor IT infrastructure, including physical and virtual resources, while Orchestrator automates workflows across System Center components to reduce manual processes.
Backup and Recovery: DPM provides backup, restore, and data recovery for Microsoft workloads, including Exchange, SQL Server, SharePoint, and Windows Server.
5. Licensing System Center in Hybrid Environments
Many organizations today are deploying hybrid environments—a mix of on-premises and cloud infrastructure. System Center can manage both on-premises and cloud resources, but understanding the licensing implications is important.
- Azure Integration: Microsoft System Center integrates with Microsoft Azure, allowing organizations to manage their on-premises infrastructure and cloud workloads. Licensing for System Centers in hybrid environments follows the same core-based model for managing physical servers and VMs.
- Azure Hybrid Benefit: By leveraging the Azure Hybrid Benefit, organizations can use their System Center licenses to manage Azure VMs, helping lower cloud costs and simplify license management.
- System Center and Azure Arc: Azure Arc extends System Center’s management capabilities beyond the traditional data center to the cloud, enabling unified management for on-premises, multi-cloud, and edge environments. In this case, System Center licensing should cover the physical hosts or VMs where workloads are running.
6. Licensing Compliance and Best Practices
Ensuring compliance with Microsoft System Center licensing is crucial to avoid penalties and optimize costs. Here are some best practices to follow:
6.1 Keep Track of Virtualization and Scaling
Managing licenses becomes easier for organizations using System Center Datacenter Edition as the number of VMs increases because of the unlimited virtualization rights. However, if you use Standard Edition, track how many VMs are deployed per host to ensure you purchase the correct additional licenses.
6.2 Use Licensing Tools
Microsoft provides tools such as the Microsoft Volume Licensing Service Center (VLSC) and System Center Configuration Manager (SCCM) to help track license usage and ensure compliance. These tools allow you to monitor your licensing status and prevent under- or over-licensing issues.
6.3 Plan for Growth
If your IT environment is expected to grow, consider purchasing System Center Datacenter Edition to accommodate increased virtualization without incurring additional licensing costs. Planning for growth helps prevent the need for constant license adjustments as the environment scales up.
7. Pricing Considerations
The cost of licensing Microsoft System Center depends on various factors, such as the number of servers, virtualization density, and the need for client management licenses. Here are some pricing considerations:
- Core Licensing Costs: Both the Standard and Datacenter Editions require core-based licenses, with a minimum of 16 cores per server. Depending on the number of cores, pricing can vary significantly.
- Subscription vs. Perpetual Licensing: System Center licenses can be purchased through a perpetual model or subscription. Subscription licensing may offer lower upfront costs, while perpetual licensing can provide a cost benefit over time.
- Software Assurance: Adding Software Assurance (SA) to System Center licenses can provide benefits such as version upgrades, technical support, and license mobility. Software Assurance is particularly useful if you move workloads to the cloud or need additional flexibility for license use.
