Virtualization & Network Connectivity

1. A Presentation by
HARDWARE & NETWORK CELL IT Department

2. •What is Virtualization?
Virtualization is Nothing But Creating Virtual Version of
Something, in Computer Terms it can be OS, Storage
Device, Network Resources.
Virtualization

3. Goal Of Virtualization
• Goal of Virtualization is to centralize administrative task while improving
scalability and overall Hardware Utilization. Many operating system can be
run on single high end server.
• An Enterprise can better manage the updates and rapid changes to OS
and applications without disturbing the users.
• Ultimately virtualization dramatically improves the efficiency and
Availability of System resources in enterprise.

4. Hardware Virtualization
• Hardware Virtualization or Platform Virtualization means
creation of virtual machine that act like real computer. For
Example Computer Running Microsoft Windows 7 May Host
The virtual machine look likes a ubuntu.
-Host Machine
-Guest Machine

5. Types Of Hardware Virtualization
• Full Virtualization :- Almost complete simulation of the actual hardware to
allow software, which typically consists of a guest operating system, to run
unmodified
• Partial Virtualization :- Some but not all of the target environment is
Simulated. Some guest programs, may need modifications to run in This virtual
environment.
• Para Virtualization :- Hardware environment is not simulated; however,
The guest programs are executed in their own isolated domains, as if they are
Running on a separate system. Guest programs need to be specifically modified
To run in this environment.

6. Creating Monitoring And
Maintenance Of Virtual Machines
• Prepare the requirement of virtual machine
Environment like how many user will connect
To the VM, How Many Applications will run on
The VM. As per requirement decide how much
Resources required for VM Like No. of Virtual
processor, RAM and NIC etc.
• Now Create the VM in hypervisor and install
The OS and All Other Application users want run.
• Keep Monitoring The VM And See How Much
Load it takes and if needed Change the resources
It uses.

7. Snapshotting of VM
• Snapshot is a state of virtual machine at an
exact time. Snapshots are taken by giving an
order to do so at a given time and can revert
on demand.
• Snapshot is extremely rapid backup technique.
• Snapshot can be moved to another machine
With its own hypervisor

8. Teleporation
• When the VM is temporarily stopped,
Snapshotted, then it can be moved to other
server and resumed on new host, this process
is known as Teleportation (or migration).
• If you take snapshot regularly then
Teleportation process become very fast
And uninterrupted to the users.

9. FailOver
• Failover allows VM to continue operations if
the host fails, in such failover case failover VM
continues its operation from last known
coherent state, rather then current state.

10. Challenges
• First challenge with virtualization is the
complexities of licensing.
• Virtualized desktop is depend on centralized
Server, storage and network.
Which puts user vulnerable to server and
Network outage or capacity limit.

11. Desktop Virtualization
• Desktop virtualization is the concept of separating the logical
desktop from the physical machine
• Desktop virtualization is more advance state of hardware
Virtualization.
• Rather than interacting with host computer directly via
Keyboard and mouse and monitor, user uses another
Computer or mobile device to interact with the server.
• Thin Clients in desktop virtualization are simple and much
Cheaper solution which are designed to connect through
The network

18. Introduction
GHCL Ltd – Sutrapada Facility is having a state of
the art Network infrastructure in place. To
Support the Business with almost 99.999%
uptime. IT Team conducts The audit of the
existing set up to study the gap Addressing the
below mentioned parameters to the HOD.
• Redundancy
• Network Scalability

19. GHCL Existing Network Setup
• Existing network is based on
the industry standard practice
of design i.e. core – distribution
& edge / access layer.
• Redundancy has been built at
the core layer by deploying the
HSRP Configuration on existing
layer – 3 switches.
• Redundancy has been built at
the link as well as path at
almost all the locations.
