What are the main benefits of Microsoft Server 2019 Datacenter?

Windows Server 2019 Datacenter is Microsoft's top 2019 server edition, built for heavily virtualized data centers and private-cloud hosts. It bundles every Datacenter-only feature: unlimited VMs, Storage Spaces Direct, Shielded VMs, and Software-Defined Networking.

VM Density – License cores once, run unlimited guests
Hyper-Converged Storage – Build resilient clusters without a separate SAN
Workload Isolation – Shielded VMs protect tenant data from admins
Hybrid Ready – Connects on-premises hosts to Azure services
Inherited Activation – Activate Standard guests automatically on this host
Long Support – Extended Microsoft support runs through January 2029

What does Microsoft Server 2019 Datacenter do?

It runs server workloads and an unlimited number of Hyper-V virtual machines on one licensed physical host, which is the core reason to choose Datacenter over Standard. On Standard you may run only two VMs per fully licensed server, then must re-license all cores for each additional pair, so dense virtualization quickly becomes cheaper on Datacenter. The edition also adds Storage Spaces Direct and Storage Replica, letting you build clustered storage from local disks instead of buying a SAN. For a host packing many VMs onto a few physical servers, this combination removes both the per-VM licensing math and the external storage cost.

How does Datacenter differ from Windows Server 2019 Standard?

The two editions share the same code base and roles, but Datacenter removes the virtualization cap and unlocks the software-defined features Standard locks out. Standard is limited to two operating system environments per fully licensed server and cannot run Storage Spaces Direct, Shielded VMs, or full Software-Defined Networking. Standard's Storage Replica is also capped at one partnership and a single 2 TB volume, while Datacenter allows unlimited replicas. Choose Datacenter when VM count is high or you need clustered local storage; choose Standard for a few fixed VMs where those features are unnecessary.

Feature	Standard 2019	Datacenter 2019
Virtual machines	2 per license	Unlimited
Storage Spaces Direct	✕	✓
Shielded VMs	✕	✓
Software-Defined Networking	✕	✓
Storage Replica	1 × 2 TB	Unlimited
Core licensing minimum	16 cores	16 cores

Does Microsoft Server 2019 Datacenter include CALs?

No. The Datacenter license covers the server operating system and its cores, but each user or device that accesses the server still needs a separate Windows Server CAL. A User CAL lets one named person connect from any number of devices, while a Device CAL lets any number of users share one device, so shift-based workers usually cost less with Device CALs. Remote Desktop sessions need a second, separate RDS CAL on top of the Windows Server CAL. Plan the CAL count before deployment, because the server runs but blocks unlicensed client access once configured for it.

Can Microsoft Server 2019 Datacenter host Remote Desktop Services sessions?

Yes, the RDS role is built in, but it needs RDS CALs and an RD Licensing server to keep working past the 120-day grace period. RDS CALs are not edition-specific, so the same CAL works on Standard or Datacenter; what matters is version, since a 2019 session host requires a 2019-or-newer RDS CAL and will reject older 2016 CALs. After the grace window expires without valid CALs installed, remote sign-ins fail. Buy the RDS CALs separately and match or exceed the server version to avoid that lockout.

What limitations should buyers know before choosing this edition?

The main constraint is licensing math rather than features: you must license every physical core, with a minimum of 8 cores per processor and 16 cores per server, even on smaller hardware. Datacenter only pays off over Standard once you run many VMs or need Storage Spaces Direct, Shielded VMs, or full SDN, since those are the features Standard lacks. Mainstream support for Windows Server 2019 has ended, and extended support runs until January 2029, so it suits workloads not yet ready for Server 2022 or 2025. Confirm your core count and CAL needs first, because both add cost on top of the base license.

What is the difference between a User CAL and a Device CAL?

A User CAL is tied to a person and lets that one user reach the server from any number of devices, while a Device CAL is tied to hardware and lets any number of users connect from that single device. User CALs fit staff who use a laptop, phone, and desktop, since one CAL covers all three. Device CALs fit shared machines such as a shift-worked terminal or a shop-floor PC used by many people. Count whichever number is lower for your environment, because mixing both types is allowed and usually cheaper.

Frequently asked questions about Microsoft Server 2019 Datacenter

Is the Datacenter VM count really unlimited?

Yes. Once every physical core on the host is licensed, Datacenter grants rights to run an unlimited number of Windows operating system environments on that server. This is the single biggest difference from Standard, which caps you at two VMs before you must re-license all cores again.

Can a Standard VM be activated by a Datacenter host?

Yes. Windows Server 2019 supports Automatic Virtual Machine Activation, so Standard or Datacenter guests inherit activation from a licensed Datacenter host without separate keys per VM. This simplifies activation across large VM fleets running on the same physical server.

Can older RDS CALs connect to a 2019 server?

No. RDS CALs are backward-compatible but not forward-compatible, so a 2016 RDS CAL cannot license a 2019 session host. You need a 2019-or-newer RDS CAL, and your RD Licensing server must run a version equal to or newer than the CAL.

The license for the software must have been granted in return for the payment of a fee which should enable the rights’ holder to obtain a remuneration corresponding to the economic value of the copy of the software.
The rights’ holder has granted the first buyer the right to use the software permanently (unlimited).
Improvements and updates, which the computer program downloaded by the subsequent purchaser has in comparison with the computer program downloaded by the first purchaser, must be covered by a maintenance contract concluded between the author/right’s holder and the first purchaser.
The original licensee must have rendered his copies unusable.
In addition, the seller must also inform the customer that the purchase of a product key by transmitting a combination of numbers and letters in digital form does not yet constitute a license to use the program legally. Corresponding information can be found on this page under point 2 and at various other places on our website.
