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. Application Operating System Application Operating System Virtualization Layer X86 Architecture CPUMemoryNICDisk

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. VMware Server Application Operating System X86 Architecture Application Operating System Application Operating System Application Operating System Windows or Linux Operating System

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 VMware Hypervisor Application Operating System X86 Architecture Application Operating System Application Operating System Application Operating System Application Service Console CPUMemoryNICDisk

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 Impact Cost effective high availability for all applications No need for dedicated stand-by hardware None 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 pools Intelligent resource allocation based on pre-defined rules Customer Impact Align IT resources with business priorities Operational simplicity; dramatically increase system administrator productivity Add hardware dynamically to avoid over-provisioning to peak load Automate 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.

Enhanced Performance Charts Quickly identify bottlenecks and isolate root causes Side-by-side performance charts in a single view Correlation and drill-down capabilities Richer set of performance metrics Aggregated Usage Key Metrics Displayed D1

Backup Anytime VMWARE CONSOLIDATED BACKUP Decouple backup from production VMs 20-40% better resource utilization Pre-integrated with 3 rd party backup products BACKUP
