Windows Server 2016 Minimm Hardware Requiremnts

CPU:

A minimum of 1.4 GHz 64-bit EMT64 or AMD64 processor. Quad Core Recommended for production systems.
Support for security features like NX Bit and DEP (Data Execution Prevention)
 The processor should support CMPXCHG16b, LAHF/SAHF, and PrefetchWNeeds
Needs to Support EPT or NPT (Second Level Address Translation)


Disk Space:

For Core installation, a minimum Disk Space of 32 GB is required. Additional 4 GB is necessary for GUI installation.

Disk Space Capacity Planning:

Microsoft Support recommends the following:

3 times the RAM size limited up to 32 GB. Which means 96 GB (32×3 = 96 GB)
Additional disk space of 10-12 GB for additional roles and features installed based on server roles. For 32 GB Systems with GUI (96 + 12 = 108 GB)
Additional 10 GB is required for Windows Updates. So, 108 GB +10 GB = 118 GB for 32 GB Systems.
10 GB extra space for miscellaneous files and logs (Perfmon, Server Trace, etc.) (128 GB for 32 GB Systems)
Any Disk Space requirements for applications that are installed on the OS partition are additional. For example SQL, Exchange, SharePoint MS-CRM, etc.


Storage Controller:

Needs to be a PCI Express Compliant Disk Controller.
ATA/PATA/IDE/EIDE are not supported for either boot, page, or data.
RAM (Random Access memory) Requirements:
512 MB ECC supported Memory Modules
800 MB for VM Installations, post-installation, reduce RAM to 512 MB.
Optional System Requirements Features:

Some of the requirements have changed compared to its predecessor, but most of the changes are already available in hardware that is sold in the market. For example, the processor feature requirements are already present in products sold for the last couple of years.
