What Is Virtual Infrastructure?

• Virtualization is a technology that allows you to transform hardware into software.

• Virtualization allows you to run multiple operating system simultaneously on a single computer.

• Each copy of an operating system is installed into a virtual machine.

• Virtualization is not either of these:• Simulation

• Emulation

How Does Virtualization Work?

• Allows multiple operating system instances to run concurrently within virtual machines on a single computer.

• A virtualization layer is installed. It uses either a hosted or hypervisor architecture.

Host Operating System-Based Virtualization

A host-based virtualization system requires an operating system (such as Windows or Linux) to be installed on the computer.

Virtualization Using a Bare-Metal Hypervisor

A bare-metal hypervisor system does not require an operating system. The hypervisor is the operating system.

The service console provides an extensible, secure management interface to the VMkernel

Before Virtualization: Single OS image per machine Software and hardware tightly coupled Running multiple applications on same

machine often creates conflict Underutilized resources Inflexible and costly infrastructure

After Virtualization: Break dependencies between OS and

hardware Manage OS and application as single unit

by encapsulating them into VMs Strong fault and security isolation VM’s are hardware-independent: they can

be provisioned anywhere

Server Virtualization Basics

Encapsulation Entire state of the virtual machine can be saved to files Move and copy virtual machines as easily as moving and copying files

Key Properties of Virtual Machines

Partitioning Run multiple operating systems on one physical machine Divide system resources between virtual machines

Isolation Fault and security isolation at the hardware level Advanced resource controls preserve performance

Hardware Independence Provision or migrate any virtual machine to any similar or different physical

server

VMotion Provides

Moves a running VM from one ESX server to another ESX server, leveraging shared storage

But the storage resource stays in the same storage location

Storage VMotion

Migrate running VM to new storage

VM stays on same host

VM disks may be individually placed

Storage type independent

Migration does not disturb VM

No downtime

Transparent to guest OS and apps

Minimal performance impact

Ensure High availability with VMware HA

What is it?Automatic restart of virtual machines in case of server failure

Customer ImpactCost effective high availability for all applicationsNo need for dedicated stand-by hardwareNone of the cost and complexity of clustering

VMware HA enables cost-effective high availability for all applications

Resource Pool

X

Resource Optimization with VMware DRS

What is it?Dynamic balancing of computing resources across resource poolsIntelligent resource allocation based on pre-defined rules

Customer ImpactAlign IT resources with business priorities Operational simplicity; dramatically increase system administrator productivityAdd hardware dynamically to avoid over-provisioning to peak loadAutomate hardware maintenance

Dynamic and intelligent allocation of hardware resources to ensure optimal alignment between business and IT

Resource Pool

Business Demand

New Resource Distribution Charts

Using Resources Pools to Meet Business Needs

A resource pool is a logical abstraction for hierarchically managing CPU and memory resources.

Configurable on a standalone host or a VMware DRS-enables cluster.

Provides resources for VMs and child resource pools.
