What is System Center Virtual Machine Manager 2012 (SCVMM)?

System Center Virtual Machine Manager (SCVMM) 2012 enables you to manage physical and virtual infrastructure. Data centers have evolved from physical to virtual to IaaS. Customers are using different services across datacenters on premises and in public cloud and managing these services costs a lot to organizations.

SCVMM 2012 provides tools to manage cloud and datacenter applications and services. Virtual Machine Manager 2012 supports Citrix, VMWare and Hyper-V infrastructure. We can pool key components like compute, network and storage resources into private cloud fabric resources and dynamically allocate, by enabling a service catalog-based self-service experience for our business. Quotas can be applied to define the level of granularity on a Shared basis or on per-user basis.

Steps to configure and use Private Cloud

1.       Configure the fabric (servers, network and storage)

2.       Create a cloud from the fabric

3.       Delegate the cloud to a Self Service User

4.       Self Service User created VMs and Services in the Cloud

 

Once hosts and fabric is configured, we can perform the below tasks to deploy virtual machines and services in VMM:

·         Create private clouds

·         Create sequenced applications

·         Create profiles (hardware, guest OS, application, SQL)

·         Create virtual machine templates

·         Create service templates

·         Deploy virtual machines

·         Deploy services

·         Scale out a service

·         Update a service

 

 

There have been a number of new enhancements made across the four pillars of the VMM 2012, as shown below: 

 

New in System Center 2012 Service Pack:

The VMM Self-Service Portal is no longer supported in System Center 2012 SP1. Instead, we recommend that you use System Center 2012 SP1 - App Controller as the self-service portal solution.

 

SCVMM 2012 also allows us to manage from the bare metal to a fully provisioned cluster.

 

 

As we can see in the VMM 2012 architecture, hypervisors can be communicated through abstraction layer that expands the scope to WDS and WSUS. Connectors are available to SCOM for monitoring the virtual resources.

 

VMM 2012 directly talks to VMWare vCenter and SQL is a necessary component of the architecture of VMM 2012.

 

VMM 2012 supports:

·         Dynamic Optimization (live-migrate workloads to get better performance and optimize the system)

·         Power Optimization (brings down unused serves to save power in the data center)

 

Out-of-Band Management gives basic level of hardware inventory, that is discovered though the baseboard management controller. Power Optimization feature can then be used to power on or off the systems.
