Windows Server 2025 Hyper-V integration with Failover Clustering creates a highly available, fault-tolerant virtualization platform where VMs automatically restart on surviving nodes if a host fails, minimizing downtime. It uses shared storage (CSV), live migration for maintenance, and advanced networking to ensure continuous service, now featuring faster, cloud-ready capabilities. Here is a detailed breakdown of this integration in Windows Server 2025:

|| Key Features and Capabilities
__Automatic VM Failover: If a physical host (node) goes down, the cluster automatically moves and restarts VMs on another healthy node, ensuring near-zero downtime.

__Cluster Shared Volumes (CSV): Allows multiple nodes in the cluster to read and write to the same shared storage simultaneously, critical for VM mobility.

__Live Migration: Enables moving running VMs between hosts with zero service interruption for planned maintenance.
Storage Spaces Direct (S2D): Supports hyper-converged infrastructure, allowing local disks on nodes to be pooled as shared storage.

__Hyper-V Replica Integration: Complements clustering with asynchronous replication for disaster recovery scenarios.
Enhanced Performance & Scalability: Generation 2 VMs now support up to 2,048 vCPUs and 240 TB of memory.

|| Core Technical Components
__Nodes: Multiple physical servers running Hyper-V.

__Shared Storage: SAN, iSCSI, or S2D to store VM files.

__Networking: Dedicated networks for cluster traffic, VM traffic, and live migration.

__Switch Embedded Teaming (SET): The recommended, mandatory networking method for high availability in WS2025.

|| Benefits in Windows Server 2025
__Improved Resiliency: Faster node detection and recovery.

__Azure Integration: Features "cloud-ready" updates and capabilities inherited from Azure Stack HCI.

__Security: Support for shielded VMs and Virtualization-based Security (VBS).

|| Essentially, this integration transforms individual Hyper-V hosts into a single, cohesive, and resilient resource pool.
