Hyper-V in Windows 8: Breaking the limits

March 10, 2012 1 comment

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.

So it is here…Get Ready for the new Wave

System Center 2012 cloud and datacenter management solutions empower you with a common management tool set for your private and public cloud applications and services. System Center helps you confidently deliver IT as a Service for your business. Virtual Machine Manager 2012 Release Candidate (RC) is key to delivering the promise of the System Center 2012 release wave. Virtual Machine Manager 2012 enables you to:

Deliver flexible and cost effective Infrastructure as a Service (IaaS). You can pool and dynamically allocate virtualized datacenter resources (compute, network, and storage) enabling self-service infrastructure experience for your business, with flexible role based delegation and access control.

Apply cloud principles to provisioning and servicing your datacenter applications with techniques like service modeling, service configuration and image based management. You can also state-separate your applications and services from the underlying infrastructure using server application virtualization. This results in a “service centric” approach to management where you manage the application or service lifecycle and not just datacenter infrastructure or virtual machines.

Optimize your existing investments by managing multi-hypervisor environments, including Hyper-V, Xen and VMware.

Dynamic optimization of your datacenter resources based on workload demands, while ensuring reliable service delivery with features like high availability.

Best-of-breed virtualization-management for Microsoft workloads like Exchange and Sharepoint.

[RHS] Error 5023 from ResourceControl for resource Cluster Disk

August 18, 2011 1 comment

This week I got a call from one of my team mates (Nashaat Sorial) telling me that he is facing a problem with his Hyper-V cluster..

He is running 3 Hyper-V hosts with Windows 2008 R2 SP1 running multiple applications. One of the hosts keep failing and He can not Live migrate any VM to the other hosts until restart.

We went through all well known workarounds for such cases like

1- if you have AV please disable

2- Also check

3- Please if you have teaming..Break it and check again

4- Please check

5- Make sure that you enable the "file and printer sharing" as well as the "client for MS networks" on the heartbeat networks cards on all nodes.

So we have to start reading more in the cluster logs. You can generate the cluster logs as per

We got some interesting data and errors in the logs just like:

In Win2008 the Physical Disk resource type private property that stores the disk signature change from "Signature" and it is now "DiskSignature" in Win2008.  The lack of the DiskSignature property not being populated was resulting in the resource failing to come online

ERROR_CLUSTER_GROUP_MOVING(5908)’ because of ”Virtual Machine Configuration R-Web2003′ is owned by node 2, not 1.’

mm.. So it looks like something from the Hardware level. Searching HP blades errors come with more useful information


he HP Integrated Management Log shows ‘ASR Detected by System ROM‘ along with the following events in the System event log on an affected machine:

Event Type:    Warning
Event Source:    hpqilo2
Event Category:    None
Event ID:    57
Failed GET SENSOR READING, sensor 16
Event Type:    Warning
Event Source:    hpqilo2
Event Category:    None
Event ID:    57
NetFN 0x4, command 0x2D timed out

The solution for this was to perform the following:

  • Install the latest ILO Firmware Update v. 1.81
  • Install the HP iLO Management Channel Interface Driver v.
  • Install the HP ProLiant iLO2 Management Controller Driver v.

All of these drivers can be downloaded form the following location, selecting your operating system:

SQL Server / Dynamic Memory Whitepaper

Today SQL Server team published a whitepaper about considerations for Dynamic Memory in SQL Server VMs.

You can download the paper from:

Running SQL Server with Hyper-V Dynamic Memory – Best Practices and Considerations


Summary: Memory is a critical resource to Microsoft SQL Server workloads, especially in a virtualized environment where resources are shared and contention for shared resources can lead to negative impact on the workload. Windows Server 2008 R2 SP1 introduced Hyper-V Dynamic Memory, which enables virtual machines to make more efficient use of physical memory resources. Hyper-V Dynamic Memory treats memory as a shared resource that can be reallocated automatically among running virtual machines. There are unique considerations that apply to virtual machines that run SQL Server workloads in such environments. This document provides insight into considerations and best practices for running SQL Server 2008 R2 in Hyper-V Dynamic Memory configurations on Windows Server 2008 R2 SP1.


I am not SQL Expert but I will try to provide any hints or comments on this Whitepaper


Enjoy it Smile
