This document provides an overview of virtualization components and tools used in VMware vSphere. It discusses key concepts like virtualization types, hypervisors, computer clusters, VMware ESXi, vCenter Server, VMware vMotion, Distributed Resource Scheduler (DRS), High Availability (HA), and Distributed Power Management (DPM). The document aims to explain how these various virtualization technologies can help implement an organizational strategy in the workplace.

Virtualization
 Virtualization, in computing, refers the act of creating a virtual (rather than
actual) version of something, including but not limited to a virtual hardware
platform, operating system (OS), storage device, or network resources.

Hypervisor
 A computer on which a hypervisor is running one or more virtual machines
is defined as a host machine. Each virtual machine is called aguest
machine. The hypervisor presents the guest operating systems with a virtual
operating platform and manages the execution of the guest operating
systems. Multiple instances of a variety of operating systems may share the
virtualized hardware resources.
 Types :
 Type 1 :
 Vmware Workstation , Virtual Box
 Type 2 :
 ESXi ,OVM

6. 6
Computer Cluster
 A computer cluster consists of a set of loosely connected or tightly
connected computers that work together so that in many respects they
can be viewed as a single system.

7. 7
Types of cluster
 High avalibility (HA)
 Load balance
 High performance computing (HPC)

VMware vSphere
VMware, Inc. is an American software company that provides
cloud and virtualization software and services, being the first who
managed to virtualize the x86 architecture. It was founded in 1998
and based in Palo Alto, California, USA. In 2004, it was acquired
by EMC Corporation and now operates as a subsidiary.
In August 2011, VMware launched ESXi 5.0, which now falls under
the vSphere 5.0 suite of products.

10. 10
ESXi 5.x
 VMware ESX and VMware ESXi are bare metal embedded hypervisors that
are VMware's enterprise software hypervisors for guest virtual servers that
run directly on host server hardware without requiring an additional
underlying operating system.
vSphere ESXi

11. 11
vCenter Server
 VMware vCenter Server provides a central location for managing all of the
virtual machines deployed inside the VMware vSphere infrastructure.

12. 12
VMware vSphere client
 The vCenter client is used to manage individual ESXi hosts as well as to
provide an administration interface to the vCenter server.

13. 13
Types of storage in Vmware vSphere
 Network file system (NFS)
 Virtual machine file system (VMFS)

14. 14
VMware vMotion
 enables live migration of virtual machines between servers with no
disruption to users or loss of service, eliminating the need to schedule
application downtime for planned server maintenance.

Distributed resource schedular (DRS)
 provides dynamic, hardware-independent load balancing and resource
allocation for virtual machies in a cluster.

High availibility (HA)
 High-availability clusters (also known as HA clusters or failover clusters) are
groups of computers that support server applications that can be reliably
utilized
with a
minimum
of
down-time.
They
operate
by
harnessing redundant computers in groups or clusters that provide
continued service when system components fail.

17. 17
VMware Disributed Power Managment (DPM)
 automates energy efficiency in vSphere Distributed Resource Scheduler
clusters by continuously optimizing server power consumption within each
cluster
