Core Viewpoint - Microsoft has officially introduced native NVMe storage support in Windows Server 2025, breaking a long-standing architectural limitation and moving away from traditional SCSI compatibility mode [1]. Group 1: Performance Improvements - The introduction of native NVMe support has led to a significant performance enhancement, with IOPS (Input/Output Operations Per Second) increasing by approximately 80% when comparing Windows Server 2025 to Windows Server 2022, based on tests with Intel dual-CPU and Solidigm 3.5TB NVMe devices [2]. - The CPU resource consumption for each I/O operation during 4K random read workloads has decreased by about 45%, allowing the system to run more virtual machines or business applications [5][6]. Group 2: Impact on Applications - The performance improvements are particularly beneficial for I/O-intensive applications such as SQL databases, Hyper-V virtualization environments, AI/ML data analysis, and high-performance file servers [6]. Group 3: Activation Process - Although the feature is built into Windows Server 2025, it is set to "off" by default for compatibility reasons, requiring manual activation [7]. - The system must be Windows Server 2025, and users need to install cumulative updates from October 2025 or later to enable this feature [10]. - Users must modify the registry to activate the feature and restart the server to complete the process [12]. Group 4: Verification of Activation - After restarting, users can verify successful activation by checking the Device Manager; if the NVMe SSD is listed under "Storage Disks" instead of "Disk Drives," the activation was successful [13].
