This document provides an overview of virtualization and VMware technologies from a presentation. It defines key concepts like hypervisors, benefits of virtualization like resource utilization and hardware independence. It also outlines VMware products like vSphere, vCenter, and their main features that provide server virtualization, live migration, high availability, and fault tolerance. Examples are given showing how virtualization with VMware can significantly reduce hardware costs and energy consumption compared to physical server deployment alone.

3. Virtualization Technology Overview
The Old /Traditional Model:
• Single OS per machine
• Software and hardware tightly
coupled
• Multiple applications often
conflict
• Underutilized resources
 Old model is challenging!

4. VmwarePresentation
Virtualization is a proven software technology that is
rapidly transforming the IT landscape and fundamentally
changing the way that people compute, such as an
Operating system, a server, a storage device or network
resources.
Ex: Run both Windows and Linux in the same machine

What is Virtualization
Hypervisor Layer

6. VmwarePresentation
“Hypervisor is a software layer sits between Hardware
and OSes which will interact with hardware and
resources and provide an interface to share the available
resources to Virtual containers.
Each operating system appears to have the host’s
processor, memory, and resources to itself. Instead, the
hypervisor is controlling the host processor and
resources.
What is Hypervisor

7. VmwarePresentation
Bare Mental/Native Hypervisors
Software systems (Virtualization Software
like VMware) that run directly on the host’s
software as a hardware control and guest
operating system monitor.
The guest operating system thus runs on
another level above the hypervisor. This is
the classic implementation of the virtual
machine architectures.
Hypervisor Classifications
Embedded/Hosted Hypervisors
Software applications (Virtualization
Software like HyperV, Xen, Citrix) that run
within a conventional operating system
environment. Considering the hypervisor
layer being a distinct software layer, guest
operating systems thus run at the third level
above the hardware

Partitioning
 Run multiple operating systems
on one physical machine
 Divide system resources
between virtual machines
Key Benefits of Virtualization
Isolation
 Fault and security isolation at
the hardware level
 Advanced resource controls
preserve performance

11. VmwarePresentation Key Benefits of Virtualization
Encapsulation
 Entire state of the virtual machine
can be saved to files
 Move and copy virtual machines as
easily as moving and copying files
Hardware-Independence
 Provision or migrate
any virtual machine to
any similar or different
physical server

12. VmwarePresentation
• Vmware vSphere5 is a Bare Mental/Native
Hypervisors which provides hardware virtualization
that presents a complete x86 platform to the virtual
machines.
• VMware vSphere, the industry-leading virtualization
platform for building cloud infrastructures, enables you
to run business critical applications with confidence
and respond to the business faster.
• It Allows multiple applications to run in isolation
within virtual machines on the same physical machine.
• It also provides direct access to the hardware resources
to give you much greater performance than software
emulation.
VMware vSphere 5

13. VmwarePresentation
• vSphere ESXi
• vSphere Distributed Resources Scheduler (DRS)
• vSphere Distributed Power Management (DPM)
• vSphere vMotion
• vSphere High Availability (HA)
• vSphere Fault Tolerance (FT)
Top vSphere Features

14. VmwarePresentation
vSphere ESXi provides a robust, production-proven, high
performance virtualization layer that abstract server
hardware resources and allow their sharing by multiple
virtual machines.
Unique memory engagement including memory
compression and advanced scheduling capabilities of the
vSphere host allow for the highest consolidation ratios
and the best application performance, in many cases,
even better than physical servers.

• Dynamic and intelligent allocation of hardware resources
• Ensure optimal alignment between business and IT

17. VmwarePresentation Top vSphere Features
vSphere Distributed Power Management (DPM)
• Consolidates workloads onto fewer servers when the
cluster needs fewer resources
• Places unneeded servers in standby mode
• Brings servers back online as workload needs
increase

Top vSphere Features
vSphere Fault Tolerance (FT)
Maximize uptime in your datacenter and reduce
downtime management costs by enabling vSphere Fault
Tolerance (FT) for your virtual machines.
FT provides zero downtime, zero data loss, and
continuous availability for your applications, without the
cost and complexity of traditional hardware or software
clustering solutions.

VMware vCenter
VMware vCenter Server, formerly known as
VirtualCenter, is a centralized management tool for the
vSphere environments allowing IT administration.
VMware vCenter Server provides a scalable and
extensible platform that forms the foundation for
virtualization management. VMware vCenter Server:
• Provides centralized control and visibility at every
level of virtual infrastructure
• Unlocks the power of vSphere through proactive
management
• Is a scalable and extensible management platform
with a broad partner ecosystem

26. VmwarePresentation
Without vmware in a data center
Suppose you got a requirement of 20 server implementation in a data center.
We consider 6 years (2190 days) service life of the servers and the UPS.
Each server requires 600w of power.
Consider,
1 server price = 5,00,000 BDT
i.e. 20 server price= 5,00,000 X 20 BDT
=1,00,00,000 BDT
Power consumption by each server (600 w) in 1 day = 14.4 Unit (KWH)
i.e.Power consumption by 20 server (600 w) in 1 day = 14.4 X 20 Unit
i.e.Power consumption by 20 server in 2190 days = 14.4 X 20 X 2190 Unit
= 630720 Unit
Recommended UPS requirement for 20 servers = 20 KVA
Backup UPS requirement for 20 servers = 20 KVA.

With VMware in a data center
Suppose you got a requirement of 20 servers. Each server requires 600w of
power. We consider 6 years (2190 days) service life of the servers and the
UPS.
You can implement 20 server on only 4 physical servers.
Consider,
1 server price = 5,00,000 BDT
i.e. 4 server price =(5,00,000 X 4) BDT
=20,00,000 BDT
Power consumption by each server (600 w) in 1 day = 14.4 Unit (KWH)
i.e. Power consumption by 4 server (600 w) in 1 day = 14.4 X 4 Unit
i.e. Power consumption by 4 server in 2190 days = 14.4 X 4 X 2190 Unit
= 126144 Unit
Recommended UPS requirement for 4 servers = 6 KVA
Backup UPS requirement for 4 servers = 6 KVA
