The document discusses server virtualization concepts including different types of virtualization like server, application, presentation, network, and storage virtualization. It describes virtual server concepts like Type 1 and Type 2 hypervisors. It also covers combinations of virtualizations, virtual desktop infrastructure, high availability and disaster recovery features in virtual infrastructures. Server virtualization consolidates multiple physical servers onto a single physical server to improve hardware utilization and reduce costs.

17. Different types of virtualizations
Server Virtualization – consolidating multiple physical servers into
virtual servers that run on a single physical server.
Application Virtualization – an application runs on another host from
where it is installed in a variety of ways. It could be done by application
streaming, desktop virtualization or VDI, Microsoft Softgrid (App-v) is an
example of Application virtualization.
Presentation Virtualization – This is what Citrix Met frame (and the ICA
protocol) as well as Microsoft Terminal Services (and RDP) are able to
create.
Network Virtualization – with network virtualization, the network is
“carved up” and can be used for multiple purposes such as running a
protocol analyzer inside an Ethernet switch.
Storage Virtualization – with storage virtualization, the disk/data
storage for your data is consolidated to and managed by a virtual
storage system. The servers connected to the storage system aren’t
aware of where the data really is.
