Client Access Licenses (CALs)
In addition to server licenses, Client Access Licenses (CALs) are essential for users or devices accessing a licensed Windows Server. CALs grant the right to access and utilize the server’s resources, such as file sharing, printing, and remote desktop services.
There are two main types of CALs⁚
- User CAL⁚ A User CAL is assigned to a specific individual, regardless of the device they use to access the server. This option is ideal for scenarios where users access the server from multiple devices.
- Device CAL⁚ A Device CAL is associated with a specific device, such as a computer or mobile device. It allows any user to access the server from that particular device.
The type of CAL you choose depends on your specific needs and usage patterns. For example, if your organization has a large number of users who access the server from various devices, User CALs might be a more cost-effective option. Conversely, if your users primarily access the server from designated workstations, Device CALs could be more suitable.
It’s important to note that CALs are not required for all Windows Server editions. For instance, Windows Server Essentials Edition does not require CALs, as it has a built-in user limit of 25 users and 50 devices.
Virtualization Rights
Windows Server licensing allows for virtualization, enabling organizations to run multiple virtual machines (VMs) on a single physical server. However, the virtualization rights vary depending on the specific edition of Windows Server.
Windows Server Standard Edition provides limited virtualization rights, allowing for up to two virtual instances of the operating system environment (VMs/OSEs) or two Hyper-V Containers. This means that you can run two virtual machines or two containers on a single server with a Standard Edition license.
Windows Server Datacenter Edition offers unlimited virtualization rights, allowing you to run as many virtual machines as you need on the licensed hardware. This is particularly beneficial for organizations with large virtualized environments or those planning to scale their virtualization infrastructure.
It’s crucial to consider the specific virtualization needs of your organization when choosing between Standard and Datacenter editions. If you anticipate running a large number of virtual machines or require the flexibility to scale your virtualization environment, the Datacenter Edition might be the better choice.
