The hardware requirements for server operating systems can vary based on the specific roles and features you plan to implement, as well as the workload you expect the server to handle. However, there are minimum hardware requirements to consider for installation. Here's a general overview for each of the mentioned Windows Server versions:
- Windows Server 2012
- Processor: 1.4 GHz 64-bit processor
- RAM: 512 MB (2 GB for Server with Desktop Experience installation option)
- Disk Space: 32 GB (more if there is 16 GB of RAM or more)
- Other: DVD drive (if installing from DVD media), Super VGA (1024 x 768) or higher-resolution monitor, Keyboard and mouse (or compatible pointing device), Internet access (optional)
- Windows Server 2016
- Processor: 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)
- RAM: 512 MB (2 GB for Server with Desktop Experience installation option)
- Disk Space: 32 GB
- Other: Ethernet adapter capable of at least gigabit throughput, Compliant with the PCI Express architecture specification. Persistent storage devices on servers classified as hard disk drives must not be PATA. Windows Server 2016 does not allow ATA/PATA/IDE/EIDE for boot, page, or data drives.
- Windows Server 2019
- Processor: 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)
- RAM: 512 MB (2 GB for Server with Desktop Experience installation option)
- Disk Space: 32 GB
- Other: Ethernet adapter capable of at least gigabit throughput, Compliant with the PCI Express architecture specification. Super VGA (1024 x 768) or higher-resolution monitor, Keyboard and mouse (or compatible pointing device), Internet access (optional)
- Windows Server 2022
- Processor: 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)
- RAM: 512 MB (2 GB for Server with Desktop Experience installation option)
- Disk Space: 32 GB
- Other: Ethernet adapter capable of at least gigabit throughput, Compliant with the PCI Express architecture specification. Super VGA (1024 x 768) or higher-resolution monitor, Keyboard and mouse (or compatible pointing device), Internet access (optional)
It's important to note that these are the minimum requirements, and meeting them does not guarantee efficient performance, especially for production environments. For production environments, it's recommended to exceed these minimums to ensure adequate performance based on the server roles and workload. Always refer to specific documentation for each version and planned roles/features for precise requirements and recommendations.
