Windows Server 2019 Datacenter: server operating system for highly virtualised environments

Windows Server 2019 Datacenter is the edition of the Windows Server 2019 generation for datacentres and Hyper-V hosts with many virtual servers. If all physical processor cores are licensed, any number of virtual machines running Windows Server may run on the server. In addition, there are features for software-defined storage, shielded virtual machines and software-defined networking. The edition is aimed at businesses that consolidate servers, build a hyperconverged infrastructure or provide virtual machines for several departments or customers.

Licensing and virtualisation rights

Microsoft licenses Windows Server 2019 Datacenter by physical processor cores. All physical cores of the server are licensed, with a minimum of 8 cores per processor and 16 cores per server. If this is met, the physical operating system environment and any number of virtual machines may be operated on this server without further server licences being required. The same applies to containers: Windows containers and Hyper-V containers can be used without limit. With Automatic Virtual Machine Activation (AVMA), Windows Server VMs on a Hyper-V host activated with Datacenter are activated via the host.

Access licences are required in addition: every user or device that accesses the server needs a Windows Server CAL, unless the Microsoft Product Terms provide for an exception. For Remote Desktop sessions, an RDS CAL per user or device is added. Neither is part of this offer.

Features of the Datacenter edition

Storage Spaces Direct combines the internal drives of 2 to 16 servers in a cluster into a software-defined storage pool. This allows compute and storage to run on the same servers without a separate storage system. For this, Windows Server 2019 adds nested resiliency for two-node clusters, which withstands two simultaneous hardware failures, as well as a performance history for the cluster.

Support for shielded virtual machines is only available in the Datacenter edition. Shielded VMs run exclusively on guarded hosts whose health has been attested by the Host Guardian Service. In Windows Server 2019, such VMs can also run Ubuntu, Red Hat Enterprise Linux or SUSE Linux Enterprise Server, and at sites with intermittent connectivity, a fallback Host Guardian Service or an offline mode can be used.

For software-defined networking, the edition contains Network Controller. New in Windows Server 2019 are encrypted virtual networks, in which traffic between virtual machines of a marked subnet is encrypted using DTLS. Storage Replica replicates volumes between servers or clusters for disaster recovery, in the Datacenter edition without limits on the number and size of volumes. The other new features of Windows Server 2019, such as Windows Admin Center, System Insights and Storage Migration Service, are also included.
