Windows Server Standard vs Datacenter: Unraveling the Key Differences You Need to Know
Have you ever wondered what the difference between Windows Server Standard and Datacenter is? Both of these options are server operating system variants, but they have unique features, advantages, and limitations. Understanding the differences is crucial for businesses that utilize large-scale IT infrastructure.
Let’s dive into the key differences you need to know.
Features
The primary difference between Windows Server Standard and Datacenter is the features they offer. Windows Server Standard provides core functionality for your business needs, including server roles and features such as Active Directory, DNS, DHCP, and file and print services. In contrast, Windows Server Datacenter provides the same features as Standard but also includes advanced features such as Storage Spaces Direct, Shielded Virtual Machines, and Storage Replica.
Licensing Model
Another significant difference between the two versions is their licensing model. Windows Server Standard can only be licensed in a physical or virtual environment for up to two processor cores per license. In contrast, Datacenter can be licensed for a physical or virtual environment with an unlimited number of processor cores. Businesses with large-scale IT infrastructure usually prefer the Datacenter licensing model due to its unlimited processor cores.
Server Virtualization
Server virtualization refers to a common IT infrastructure resource-sharing technique that allows multiple operating systems to run on a single server simultaneously. Windows Server Datacenter provides some virtualization perks that are not available in Standard, such as the ability to run an unlimited number of VMs on a single licensed physical server. This feature can significantly benefit larger businesses that require multiple virtual machines to reduce costs and optimize their IT infrastructure.
Failover Clustering
Failover clustering is an essential element of business continuity, and it allows a business to avoid data loss and downtime in the event of a server crash. However, this feature is only available in Windows Server Datacenter. Failover Clustering in Datacenter enables businesses to create clustered environments that have shared disks and VMs, making it possible to run applications that never stop, even when a server fails. Standard only provides basic failover clustering capabilities, making it less attractive for larger businesses.
Storage Spaces Direct
Storage Spaces Direct is a feature available only in Datacenter, and it enables businesses to utilize the local storage of clustered servers for storing data. This feature can be especially useful for businesses that want to create highly available and scalable storage solutions without having to invest in expensive SAN hardware.
Nested Virtualization
Nested Virtualization is a newer technology that allows running Hyper-V inside a Virtual Machine (VM). This feature isn’t typically used in production environments, but it can be valuable for testing and development. Windows Server 2016 Datacenter supports Nested Virtualization, while Windows Server Standard doesn’t.
Cost
Finally, there’s the question of cost. Windows Server Standard is less expensive than Datacenter, but it offers fewer features. This makes it a better option for small to medium businesses with a lower dependency on advanced IT infrastructure. In contrast, Windows Server Datacenter is more expensive but provides more advanced features, and it’s suitable for large-scale businesses with advanced IT infrastructure.
FAQs

Q. Can I use Standard to create a failover cluster?
Yes, you can create a failover cluster using Windows Server Standard, but it has specific limitations. Windows Server Standard only supports a maximum of two nodes, while Windows Server Datacenter supports unlimited nodes.
Q. Will I miss out on anything if I choose Windows Server Standard over Datacenter?
You will miss out on advanced features such as Shielded Virtual Machines, Storage Replica, Storage Spaces Direct, and more. However, these features may not be necessary for businesses with smaller-scale IT infrastructure.
Q. Does Standard support virtualization?
Yes, Windows Server Standard supports virtualization. However, it has some limitations in regards to the number of VMs allowed and hardware resources allocation.
