Hyper-V in Windows 8: Breaking the limits

The next release of Windows Server, Windows Server "8", offers businesses and hosting providers a scalable, dynamic, and multitenant-aware, cloud-optimized infrastructure. Download Windows Server "8" Beta

Hyper-V in Windows Server 8 introduce a new challenge to the world of IT, breaking the limits With Windows Server 8 we have a new Hyper-V features that increase scale, performance, and density of your virtualized environment. The main features included are:

•  Hyper-V host scale and scale-up workload support
•  Dynamic Memory improvements for Hyper-V
•  Resource Metering in Hyper-V
•  New virtual hard disk format
•  Offloaded Data Transfer support in Hyper-V
•  Data Center Bridging (DCB)
•  Virtual Fiber Channel in Hyper-V
•  Support for 4-KB disk sectors in Hyper-V virtual disks
•  Quality of Service

I will try to cover these features on my next posts but the most important part the Hyper-V scale matrix is not going linear it is just breaking the limits Smile

Windows Server 8 Beta Hyper-V Scale Metrics:

  • 160 logical processors per host
  • 1024 VMs per host
  • 64 nodes per cluster
  • 4000 VMs per cluster
  • 32 virtual processors per VM
  • 1 TB memory per VM (No taxes, no entitlements, no penalty for buying a large scale up server) 
  • 64 TB per VHDX

In addition, these scalability metrics lead the industry:

  • VMware vSphere 5.0 support up to 32 nodes in a cluster. Windows Server 8 Hyper-V supports 64 nodes. (2x over VMware)
  • VMware vSphere 5.0  supports virtual disks up to 2 TB in size. Windows Server Hyper-V 8 supports virtual disks up to 64 TB in size (32x over VMware)
  • VMware vSphere 5.0 supports 3,000 VMs per cluster.  Windows Server 8 supports 4,000
  • VMware vSphere 5.0 supports 512 VMs per host.  Windows Server 8 supports 1,024

While VMware supports up to 1 TB of memory per VM, you have to purchase vSphere 5.x Enterprise Plus ($3,500 per processor) and then purchase memory entitlements (taxes) to achieve this goal. Hyper-V 8 has no such tax or entitlement. Such taxes are an anathema to our customers. Every version of Windows Server 8 that ships with Hyper-V will support up to 1 TB of memory per VM.
