Windows Server 2022 is the new long-term servicing channel release of Windows Server for on-premises data centers and virtual machines. The two main editions are Standard and Datacenter. While the two editions of Windows Server 2022 offer the same core server features that build on existing Windows Server functionality, there are some differences around how they support Hyper-V virtual machines and how they manage networking and storage.
If you’re building a virtual infrastructure, then you will need to choose Datacenter, as it adds support for unlimited VMs (Standard only supports two), along with shielded Hyper-V VMs for enhanced isolation and security, and support for both software-defined networking and storage.
Minimum system requirements remain the same:
- 1.4 GHz 64-bit processor
- Compatible with x64 instruction set
- Supports NX and DEP
- Supports CMPXCHG16b, LAHF/SAHF and PrefetchW
- Supports Second Level Address Translation (EPT or NPT)
- 512 MB (2 GB for Server with Desktop Experience installation option)
- ECC (Error Correcting Code) type or similar technology, for physical host deployments
- An Ethernet adapter capable of at least 1 gigabit per second throughput
- Compliant with the PCI Express architecture specification
- UEFI 2.3.1c-based system and firmware that supports secure boot
- Trusted Platform Module 2.0
