3.  Why Server Virtualization
 Flexible Infrastructure
 High Availability & Resiliency
 Virtual Machine Migration
 Summary & Wrap Up

5. Server virtualization is a virtualization technique that involves
, with the help
of virtualization software. In server virtualization, each virtual server runs
multiple operating system instances at the same time.

6.  Reduce footprints of datacenter
 Reduce Hardware, Software License and Operating Cost
 Save In Utility bill
 Simplify The Administration Overhead
 Improve the application performance
 Ensure high availability
 Gain operational flexibility

7. What Savings Virtualization Brings?
 Reduced hardware costs – Ideally, 1 physical machine can be divided into 8-16 virtual ones.
This leads to hardware saving on every virtual machine.
 Reduced power consumption and cooling needs.
 Savings on physical space in the data center.
 Rapid deployment – The ability to rapidly deploy a new system without purchasing or
building new hardware.
 Increase availability of hardware and applications for business continuity:-Securely backup and migrate
entire virtual environments with no interruption in service. Eliminate planned downtime
and recover immediately from unplanned issues.

19. Hyper-V Host
VM1 VM23 Types of Hyper-V Network
• Private = VM to VM Communication
• Internal = VM to VM to Host (loopback)
• External = VM to Outside & Host
Each vNIC can have multiple VLANs attached to it,
however if using the GUI, only a single VLAN ID can
be specified.
Set-VMNetworkAdapterVlan -VMName VM01
-Trunk -AllowedVlanIdList 14,22,40
Creating an external network transforms the chosen
physical NIC into a switch and removes TCP/IP stack
and other protocols
Optional host vNIC is created to allow
communication of host out of the physical NIC
Connecting VMs to each
other, and the outside world

20. Extensible Switch
• Virtual Ethernet switch that runs in the
management OS of the host
• Exists on Windows Server Hyper-V, and
Windows Client Hyper-V
• Managed programmatically
• Extensible by partners and customers
• Virtual machines connect to the
extensible switch with their
virtual network adaptor
• Can bind to a physical NIC or team
• Bypassed by SR-IOV
