Hyper-V Windows Server Hosts — Optimized for Microsoft Virtualization

Hyper-V is the default Microsoft virtualization stack — built into Windows Server 2019/2022 Datacenter at no extra licence cost. We stock hardware on Microsoft's official Hyper-V hardware compatibility list (Windows Server Catalog) so you get predictable behaviour with VM Manager, Azure Stack HCI, and System Center.

The Hyper-V sweet spot is Dell PowerEdge R740/R750 or HPE ProLiant DL380 Gen10/Gen11 with dual Xeon Gold processors. Microsoft validates these heavily for Azure Stack HCI — meaning you can later promote a standard Hyper-V cluster to a managed cloud cluster with no hardware refresh.

Sizing rule of thumb for general-purpose Hyper-V hosts: 8 GB RAM per VM × 25-40 VMs per host = 256-512 GB RAM per node. CPU: 1.5-2× overcommitment of vCPU to physical cores is comfortable for office workloads (HR systems, file/print, light databases).

For high-density VDI on Hyper-V (using RDS), bump to 768 GB+ RAM and add NVIDIA RTX vDWS-licensed GPUs. For Storage Spaces Direct (S2D) hyper-converged Hyper-V, validate 4× 1.6 TB SAS/NVMe in mirror-accelerated parity layout per node — we stock the certified ones.

Frequently Asked Questions

How many VMs can a Hyper-V host run?

A dual-socket server with 24 cores per CPU and 512 GB RAM comfortably runs 40-80 general-purpose VMs (8 GB RAM, 2 vCPU each) at 1.5x CPU overcommitment. Microsoft supports up to 1,024 VMs per Hyper-V host and 8,192 VMs per cluster.

Is Hyper-V free?

Yes for the hypervisor (Microsoft Hyper-V Server is a free standalone download). However, Windows Server Datacenter licensing on the host gives you unlimited Windows guest VMs included — that bundled deal makes it cheaper than buying separate Standard licences for each VM. Datacenter licensing is per-physical-core ($6,155 list per 2-core pack).

Should I use Hyper-V or VMware ESXi?

Hyper-V wins on cost if your guest OS is Windows (you get free guest Windows licences with Datacenter). VMware wins on third-party ecosystem (more storage/backup vendor integrations, vSAN maturity). For most Microsoft shops, Hyper-V is the default; for mixed environments with strong VMware skills, ESXi remains popular.

Can I run Linux VMs on Hyper-V?

Yes — Microsoft maintains the Linux Integration Services (LIS) drivers for Ubuntu, RHEL, CentOS, SUSE, and Debian. Performance is on par with VMware ESXi for Linux guests, especially with Generation 2 VMs which support UEFI boot and PXE.
