Dynamic Data Center: Toolkit to create a private or public cloud based on Microsoft’s Hyper-V and System Center
To make it easier for hosting providers to create Dynamic Data Centers, Microsoft is providing a set of documents and code samples that will serve as guidelines and best practices.
The set of documents provided is as follows:
- Bare-metal provisioning of Windows Server 2008 to host virtual environments
- Provisioning a virtual environment (using Hyper-V). This document outlines:
- Configurations to deploy a virtual infrastructure based on Windows Server 2008 Hyper-V.
- Configuring the Active Directory® service to make it easier to create a multi-tenant environment.
- Securing the environment.
- Managing the virtual environment using System Center Virtual Machine Manager.
- Best practices to configure and use Virtual Machine Manager.
- Capacity planning.
- Installing and configuring System Center to manage your virtual environment
- Leveraging System Center Data Protection Manager to back up/restore the virtual environments in a delegated administration model
- Configure System Center Configuration Manager to:
- Perform updates on demand.
- Track inventory.
- Push out standard configurations and software.
- Configure System Center Operations Manager to monitor and alert individual end customers based on policies
In addition to these documents, Microsoft released a Silverlight™-based test portal for ContosoHosting.com. This portal includes a control panel that enables end customers to:
- Provision and manage Hyper-V–based clients.
- Perform file/folder-level backups and restores.
- Monitor important counters and receive alerts.
- Install updates during a configurable time window.
- Monitor events.
Along with the sample application, there is a source code for Windows® Communication Foundation (WCF) services and Windows Powershell™ scripts to perform all operations to provision and manage the System Center Server Management Suite Enterprise and Windows Server 2008

Hyper-V R2 cluster: Maximo numero de VM’s por nó
Planeje recursos o suficiente para permitir que um pelo menos 1(um) nó seja reservado para failover, o que significa que ele permanecerá ocioso até que outro nó receba o failover para ele. (nó passivo)
Minha recomendacao : reserve 2 nós como passivos. Não há uma taxa ou um multiplicador de nós reservados recomendados para nós ativos. A única exigência específica é que o número total de nós em um cluster não pode exceder o máximo de 16.
Vários fatores podem afetar o número real de máquinas virtuais que podem ser executadas ao mesmo tempo em um nó, como:
- Uma quantidade de memória física sendo usada por cada máquina virtual.
- Largura de banda de armazenamento e rede.
- Número de eixos de disco, o que afeta o desempenho de E/S do disco
Note que a alta desidade de VM’ em um cluster Hyper-V R2 requer uma capacidade alta de IO capability no Storage. Este sim pode ser o fator limitante.
Numero de Nós no Cluster | Media de VM’s por nó | Max # VMs no Cluster |
2 Nodes (1 active + 1 failover) | 384 | 384 |
3 Nodes (2 active + 1 failover) | 384 | 768 |
4 Nodes (3 active + 1 failover) | 333 | 1000 |
5 Nodes (4 active + 1 failover) | 250 | 1000 |
6 Nodes (5 active + 1 failover) | 200 | 1000 |
7 Nodes (6 active + 1 failover) | 166 | 1000 |
8 Nodes (7 active + 1 failover) | 142 | 1000 |
9 Nodes (8 active + 1 failover) | 125 | 1000 |
10 Nodes (9 active + 1 failover) | 111 | 1000 |
11 Nodes (10 active + 1 failover) | 100 | 1000 |
12 Nodes (11 active + 1 failover) | 90 | 1000 |
13 Nodes (12 active + 1 failover) | 83 | 1000 |
14 Nodes (13 active + 1 failover) | 76 | 1000 |
15 Nodes (14 active + 1 failover) | 71 | 1000 |
16 Nodes (15 active + 1 failover) | 66 | 1000 |
