• Virtualization Overview

• VMware Virtualization Technology

• Architectures and Use Cases

• Why VMware?


What is Virtualization

Virtualization is an abstraction layer that decouples the physical hardware from the operating system to deliver greater IT resource utilization and flexibility”

It allows multiple virtual machines, with heterogeneous operating systems to run in isolation, side-by-side on the same physical machine.

Each virtual machine has its own set of virtual hardware (e.g., RAM, CPU, NIC, etc.) upon which an operating system and applications are loaded.

The operating system sees a consistent, normalized set of hardware regardless of the actual physical hardware components

What is Virtualization?

• VMware provides hardware virtualization that presents a complete x86 platform to the virtual machine

• Allows multiple applications to run in isolation within virtual machines on the same physical machine

• Virtualization provides direct access to the hardware resources to give you much greater performance than software emulation

CPU Utilization

• Server utilization is low today

Source: VMware Capacity Planner customer analysis

But ability to utilize that computing capacity is low and continuing to decrease

• And technology advances continue to drive it lower

• Increasing clock speeds• Hyperthreading• Dual-core systems


What are the business drivers ?

Save Money!• Lower TCO

• Cost Avoidance vs. Cost of Business As Usual

• According to Gartner 85% of x-86 servers are only utilizing 15% or less of its computing resources

• ~ 72% of IT resources perform maintenance & support tasks, only 28% are assigned to support strategic initiatives

Improve Flexibility in the x86 environment• Significantly reduce provisioning time

• Create a proactive “lights on” datacenter

• Enable workload management / capacity on demand

• Architect IT as a profit center

Operational Efficiency• Reduce or eliminate maintenance windows

• Enable cost affective DR opportunities

• Respond quicker to business demands on IT


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

Hardware-Independence Provision or migrate any virtual machine

to any similar or different physical server

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

VMware Infrastructure – Key Solutions / Use Cases

Server Consolidation and Containment – Eliminate server sprawl by deploying systems into virtual machines

Test and Development – Rapidly provision and re-provision test and development servers; store libraries of pre-configured test machines

Enterprise Desktop – Secure unmanaged PCs. Alternatively, provide standardized enterprise desktop environments hosted on servers.

Business Continuity – Reduce the cost and complexity of business continuity by encapsulating entire systems files that can be replicated and restored onto any target server

Infrastructure Provisioning – Reduce the time for provisioning new infrastructure to minutes with sophisticated automation capabilities.

Legacy Application Re-hosting – Migrate legacy operating systems and software applications to virtual machines running on new hardware for better reliability


Server Consolidation and Containment


Resource Pools

Aggregate collections of disparate hardware resources into unified logical resource pools

Failed server mean less resources not a failed application

Dedicated (virtual) infrastructure for each business unit; central IT retains control over hardware

Delegation of resource and virtual machine management down to the business unit

Management of an entire SOA application stack as a single entity

Network VirtualizationSimplify port configuration by

utilizing a single configuration object across large groups of ports

Expanded port configuration policies including:

• NIC teaming policy (now per port instead of per virtual switch)

• VLAN tagging • Layer 2 security • Traffic shaping

Flexible virtual switches. • Create Virtual switches with any

number of ports from 8 to 1016

• Max number of virtual switches has been raised from 128 to 248

• Scale up to handle more virtual machines

"We can deploy servers in a pinch. With VirtualCenter, it takes 10 minutes. It's absolutely fantastic to be able to deliver a server and have the applications up, have them tested and then put them in production in a matter of four or five hours."

What The Analysts Say About VMware

Illuminata“…VMware is one of the very few

who have the deep experience needed to create, harden, and

optimize complex, sophisticated virtualization products.”

Gartner“Enterprises that do not leverage

virtualization technologies will spend 25 percent more annually for hardware, software, labor and

space for Intel servers…”

Forrester“Forrester believes that Intel’s

economies of scale will eventually shift most computing workloads to

Intel- or AMD- based servers. And VMware now makes it

possible to bring the Organic IT benefit of high utilization to underutilized Intel servers.”

Gartner(formerly Meta Group)

“There is very strong market momentum for VMware within

META Group’s Global 2000 client base. VMware has become the de

facto standard for Intel server virtualization.”
