Microsoft’s hardware virtualization platform that enables multiple virtual machines (VMs) to run on a single physical host, widely used to virtualize SQL Server workloads.
- SQL Server is fully supported on Hyper-V and other hypervisors: These include VMware vSphere and Nutanix AHV. Virtualization is the standard deployment model for most SQL Server instances today.
- DBAs managing virtualized SQL Server environments must understand how CPU, memory, and storage resources are shared: Resource contention at the hypervisor level can directly impact database performance.
- Key Hyper-V considerations for SQL Server include: Avoiding memory over-commitment by using static or minimum reserved memory, assigning dedicated virtual CPUs to SQL Server virtual machines, and configuring storage with appropriate queue depth.
- NUMA topology requires special attention: Hyper-V virtual NUMA should be configured correctly, as misconfigured virtual NUMA can lead to significant SQL Server memory management issues.
- Hyper-V supports SQL Server in guest virtual machines only: SQL Server itself does not run as a Hyper-V component.
