System Center R2 Virtual Machine Manager Introduction

A SCVMM2012R2 Overview:

Virtual Machine Manager (VMM) is a key component in the System Center 2012 product family, a management solution for virtualized data centers that enables you to configure and manage virtual hosts, networks, and storage resources. To create and deploy virtual machines and services to the private cloud that you create. Virtual Machine Manager R2 can help you achieve:

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

2. Apply cloud principles to build and service your datacenter applications through service modeling, service provisioning, and image-based management. You can also use server application virtualization to decouple the state of your applications and services from the underlying infrastructure. This enables a "service-centric" approach to managing the lifecycle of applications and services, not just for data center infrastructure or virtual machines.

3. Optimize your existing investments by managing multiple hypervisor environments, including Hyper-v,xenserver and VMware VSphere. Workload-based requirements ensure that reliable services are delivered with high availability, enabling dynamic optimization of your data center. In its class, it is the best virtualization management scenario for Microsoft workloads such as Exchange or SharePoint.

4. Integrated management of Windows Server Update Services enables coordinated cluster patching.

II: SCVMM2012R2 Architecture Overview

System Center R2 Virtual Machine Manager is primarily composed of a VMM Management Server, VMM console, VMM database, VMM library server, VMM PowerShell, and a unified console provided by one An app Controller2012 R2 that can help you manage public and private clouds, as well as cloud-based virtual machines and services. Figure one is a single-node architecture. Figure II is a multi-node cluster environment. Figure III is the complete functional architecture diagram for system Center R2 Virtual Machine Manager.

Might

VMM Management Server	The Virtual Machine Manager service runs on the computer and handles the command and control communication with the VMM database, the library server, and the virtual machine host
VMM Database	A Microsoft SQL Server database stores VMM configuration information
VMM Console	This program enables you to connect to a VMM Management Server to centrally view and manage physical and virtual resources such as virtual hosts, virtual machines, services, and library resources.
VMM Library and library server	A directory of resources (for example, virtual hard disks, templates, and configuration files) that are used to deploy virtual machines and services. Library servers host shared folders that are used to store file-based resources in the VMM library
VMM PowerShell	Windows PowerShell-based command-line interface that allows users to access cmdlets that perform all the functions in VMM

VMM enables you to configure and manage the following resources. These resources need to be configured before you can deploy virtual machines and services to private clouds or virtual hosts:

Store	Storage resources for use with Hyper-V hosts and host clusters, such as storage classifications, logical units, and storage pools
Internet	network resources for deploying virtual machines and services, such as logical networks, IP address pools, and load balancers
Virtual Host	Microsoft Hyper-V, Citrix XenServer, and VMware ESXI hosts and host clusters on which you will deploy virtual machines and services. You can create host groups to organize hosts based on physical site locations, resource allocations, or some other criteria
Library server and library sharing	A directory of resources (for example, virtual hard disks, templates, and configuration files) for deploying virtual machines and services

at System Center SP1, the role of the VMM self-service portal has been removed, and using System Center 2012-app Controller as a self-service solution can help you easily configure in the private cloud and public cloud, Deploy and manage virtual machines and services. We will introduce this system Center R2 component in the next chapter.

The System Center R2 Virtual Machine Manager feature consists of four parts: deployment, construction, cloud, and service. Such as

Three: SCVMM2012R2 demand

(i) hardware Requirements

1. no more than 150 hosts managed

Hardware components	Minimum	Recommended
Processor	Pentium 4,2 GHz (x64)	Dual-processor, dual-core, 2.8 GHz (x64) or faster
Ram	2 GB	4 GB
Hard disk space-no local VMM database	2 GB	+ GB
Hard disk space-Microsof SQL Server with local full version	GB	GB

2. management of more than 150 host units

Hardware components	Minimum	Recommended
Processor	Pentium 4,2.8ghz (x64)	Dual-processor, dual-core, 2.8 GHz (x64) or faster
Ram	4 GB	8 GB
Hard disk space	GB	GB

To improve performance, when you manage more than 150 hosts, it is recommended that you use a dedicated computer for the VMM Management Server and do the following:

? Add one or more remote computers as a library server, and do not use the default library share on the VMM Management Server.

? Use the version of SQL Server that is installed on the other computer for the VMM database.

(ii) software Requirements

1. Windows Remote Management (WinRM) service

2. Microsoft. NET Framework 4.5 or Microsoft. NET Framework 4.5.1

3. Windows ADK for Windows Server R2

4. SQL Server R2 and later a new SQL Server command prompt
