Solution Guide 5

Introduction

Dell PowerEdge servers enabled with VMware ESX Server 3i represent the

next generation of servers designed specifically for virtualization. Through its

close partnership with VMware, Dell is able to offer qualified VMware-based

virtualization solutions optimized for today’s active data centers.

With its hardware-like footprint, VMware ESX Server 3i offers a standards-

based management solution designed for reduced deployment time,

centralized management, and increased security. When coupled with energy

efficient Dell PowerEdge servers, you can also take advantage of reduced

power and cooling needs, the latest in CPU technologies, reduced server

downtime, and greater reliability.

This guide will help you understand the differences between ESX Server 3i

and ESX Server 3 versions of VMware’s Virtual Infrastructure 3 (VI3)

products as they are deployed on Dell servers, how to deploy, manage, license,

and support your solution, and Dell’s deployment best practices. A

deployment best practices checklist is also provided (see "Appendix A:

Deployment Best Practices Check List" on page 26).

NOTE: Although this guide will help you use your ESX Server 3i enabled

PowerEdge server, you are also encouraged to review the information provided by

VMware (www.vmware.com).

VMware ESX Server 3i Features

Ease of Deployment

VMware ESX Server 3i is sold as an OEM product pre-installed on Dell

servers. Because ESX Server 3i is pre-installed, your server can be deployed

within minutes by simply connecting a keyboard, monitor, and mouse, and by

enabling basic Ethernet-based connectivity for management traffic; there is

no need to configure local storage, install ESX from CD, or configure the

server via the service console. With server data center deployments often

handled by several technicians and engineers through a formal deployment

process, eliminating these steps may save time and simplify IT deployment

flows.

6Solution Guide

Integrated Management and Health Monitoring

Tightly integrated with the Dell PowerEdge platforms, VMware ESX Server 3i

uses the standards-based Common Interface Model (CIM) to monitor

(graphically) the PowerEdge server on which it is running and provide up-to-

date system health information. This information is available for one or more

servers within the Virtual Infrastructure Client (VI Client) and includes the

following data: internal storage array, physical and logical drive health, and

analog system parameters, such as cooling fan speeds and system board

ambient temperature readings. The ESX Server 3i kernel also supports SNMP

alerting, a widely adopted management protocol. SNMP support allows you

to integrate your PowerEdge systems into your existing management

infrastructure.

In addition, VMware’s software is now able to take advantage of power

monitoring capabilities offered by Dell PowerEdge servers. You can monitor

instantaneous power usage and input voltages, as well as cumulative power,

max current and max power usage since last reset.

For more information about systems management with VMware ESX Server

3i on Dell PowerEdge servers, and a comprehensive management guide

greatly expanding on the architecture, out-of-band management, and

baseboard management controller (BMC) capabilities of this solution, please

visit www.dell.com/vmware.

Enhanced security

With a service console based on a hardened Linux®distribution, ESX Server

software already helps provide a secure virtualization environment.

ESX Server 3i further enhances security by eliminating the service console

altogether, which simplifies the process of securing the IT infrastructure by

reducing the number of open network ports and preventing other programs

that can compromise security from being installed.

Reduced Patch Management

Removal of the service console in ESX Server 3i simplifies patch

management, reducing VMware support costs, simplifying IT processes and

maintenance scheduling, and improving host security.

Solution Guide 7

Improved Reliability

Hard drives represent one of the greatest sources of hardware failures in data

center environments. Shared storage arrays (fibre channel or iSCSI) are better

suited for virtual machine (VM) and data storage than local hard drives,

providing higher levels of performance and increased single point of failure

recovery. Additionally, solid-state, internal storage is easier to configure than

other hard drive-less solutions, such as Boot-from-SAN. Because shared

storage arrays are required to take advantage of ESX Server 3i enterprise and

standard-level features, Dynamic Resource Scheduling (DRS) and High-

Availability (HA), server local hard drives are not needed.

Rapid Deployment and Provisioning

Dell offers VMware ESX Server 3i pre-installed direct from the Dell factory,

enabling greatly simplified data center deployment and provisioning. For the

first time, VMware users have the ability to go from box to rack to processing

workloads in minutes.

Solution Guide 9

Figure 1. VMware Infrastructure Components Using Dell PowerEdge Systems and

Storage Systems

Diagram Components:

• ESX Server — allows multiple operating systems to run simultaneously on

a single PowerEdge system.

• VirtualCenter Server — manages multiple ESX Servers and runs on

Windows Server 2003. VirtualCenter is optional and is required for

advanced management capabilities such as VMotion, DRS, and HA.

• VirtualCenter Database — stores all of the configuration data about a

VMware Infrastructure. It is recommended that you use a professional

database such as Microsoft SQL Server™ or Oracle™ for the VirtualCenter

database.

• License Server — authorizes ESX Server hosts and the VirtualCenter

server per the purchased license keys and licensing agreement. It is

recommended to install the license server on the VirtualCenter host. This

can also reside on a separate host. License server is required when using a

centralized licensing model, but is not required for host-based licensing.

For more information on the different licensing configurations, see the

10 Solution Guide

Installation Guide

and

Upgrade Guide

for ESX Server 3 under VMware

Infrastructure 3 on the VMware documentation website at

www.vmware.com/support/pubs

• VMware Infrastructure Client - installs on a system running a supported

Windows operating system and is the primary tool to manage an ESX

Server host by directly connecting to it or through the VirtualCenter

server.

• Virtual Machine Storage — stores virtual machine configuration and

virtual disk files. This can be either an internal storage local to the ESX

Server or an external storage that can be shared by multiple ESX Servers.

Advanced features such as VMotion, DRS, and HA require that the virtual

machine’s disk and configuration files are stored on external shared

storage.

• VMware Infrastructure Web Access — a web interface for managing

virtual machines and accessing remote consoles.

Guidelines

Before deploying VMware Infrastructure, follow the guidelines below:

• Determine the licensing mode that will best suit the deployment

environment and design the licensing infrastructure accordingly.

• Determine the type of storage (local SCSI/SAS/SATA, iSCSI, or Fibre

Channel SAN) for hosting virtual machines that will best suit the

deployment environment and design your storage infrastructure

accordingly.

• Determine the number of logical unit numbers (LUNs), size of the LUNs,

RAID level of the LUNs, and the number of storage groups.

• Determine the number of virtual machines that will run on the ESX

Servers and their corresponding workloads.

• Size the resource requirements for the virtual machines, such as the

microprocessor requirements, memory size, and networking. For more

information on general sizing and scaling studies, see the documentation

available on the Dell and VMware Alliance website at
