SharePoint 2010 Virtualization

With virtualization we can have multiple virtual servers(OS) on the single physical server. For example we can have web server, application server and database server on a single physical server.This approach not only help with cost reduction and maintenance but also with response time, high availability and scalability with business needs.

For SharePoint 2010 virtualization, Windows Server 2008 R2 with Hyper-V contains tool set which help to achieve reduces cost and increase performance.

Benefits of Virtualization:

1. Restore previous server instance: Administrator can take snapshot of the servers on timely basis so that if something goes wrong with server settings or installation, he can restore previous server's snapshot.
2. Virtualization tool-sets ensures that physical hardware like processor, RAM are used to the full capacity. For example: In a small physical farm, we have 2 web servers, 1 application server, 1 DB server. There are times when these physical servers are not used at full capacity. Virtualization handles these parameters dynamically in-turn increasing application's performance.
3. Multiple applications with different software requirement can sit on one physical server. For example: We have MOSS 2007 portal and SharePoint 2010 portal to deploy on PROD. We can create 2 different operating systems on same physical server using virtualization.          
4. We can scale up or down easily with virtualization. For example, a small organization can use virtualization to built small farm (2WFEs,1App,1DB) on single physical server and as organization grows they can easily add couple of physical servers instead of switch from stand alone to small farm. 
5. Dynamic memory distribution treats memory as shared resource that can be reallocated automatically among running virtual machines

Generally Indexing server and Database server are not virtualized because they actually consume all the resources of physical server and there is little scope of physical server's resource sharing using virtualization.
