This document is a companion guide to the VMware ESX 4 guides.
This document helps you to deploy ESX 4 on Dell PowerEdge systems and
provides specific information on recommended configurations, best practices,
and additional resources.
NOTE: For information on deploying ESXi 4, see VMware ESXi 4 on Dell PowerEdge
Systems Deployment Guide at support.dell.com/manuals.
VMware License Offerings
Dell offers the following VMware editions:
•vSphere Essentials Plus
•vSphere Standard
•vSphere Enterprise
•vSphere Enterprise Plus
•vCenter Server
•vSphere Standard Acceleration Kit (8 sockets)
•vSphere Enterprise Acceleration Kit (6 sockets)
•vSphere Enterprise Plus Acceleration Kit (6 sockets)
NOTE: The latest releases to include both ESX and ESXi hypervisor architectures
are vSphere 4.1 and its subsequent update and patch releases. Future major
releases of vSphere will include only the ESXi architecture. It is recommended that
you consider a plan for migrating to ESXi starting with this release.
NOTE: vSphere Essentials Plus is an all-inclusive package that includes licenses
for three physical systems, each system with up to two processors. It also includes
VMware vCenter Server to centrally manage the systems. vSphere Essentials Plus
edition is supported only on two-socket systems. The additional licenses must still
be deployed on approved systems for Dell support.
NOTE: vSphere Acceleration Kits are packages of vSphere licenses plus a vCenter
Server Standard license for initial deployments. All the licenses provided are on the
same VMware contract and Dell support contract. The additional licenses must be
deployed on approved systems for Dell support.
ESX 4 Deployment Guide5
ESX Architecture Overview
ESX allows multiple operating systems to run simultaneously in virtual
environments on a single physical system. These virtual environments,
referred to as virtual machines (VMs), can be created and managed faster
than conventional systems. The VMs do not interact directly with the
physical hardware. Each of these VMs runs in a resource-isolated,
secure environment and can include Microsoft
Novell NetWare, and Solaris operating systems with their
associated applications.

vSphere infrastructure consists of the following components:
ESX
— Allows multiple operating systems to run simultaneously on
asingle system.
vCenter Server — Runs on Windows-based operating systems and
monitors and manages VMs and copies of ESX. With vCenter Server,
you can create, start, stop, and migrate VMs across the entire physical
data center. vCenter Server is optional and is required for advanced
management capabilities such as VMware VMotion, Distributed
Resource Scheduling (DRS), and High Availability (HA).
ESX 4 Deployment Guide7
•
vCenter Server Database
— Stores all the configuration data about
vSphere. It is recommended that you use a production database such as
Microsoft SQL Server or Oracle for the vCenter Server database.
•
License Server
— Authorizes ESX hosts and vCenter Server as per the
purchased license keys and licensing agreement. It is recommended to
install the license server on the vCenter Server host. This can also reside
on a separate host.
NOTE: A license sever is not required for ESX 4 hosts. However,
if vCenter Server manages the ESX 3.0.x or ESX/ESXi 3.5 hosts,
you require a license server.
•
vSphere Client
— Manages an ESX host by directly connecting to it or
through the vCenter Server. It is installed on a system running a supported
Windows operating system.
•
VM DataStore
— Stores VMs configuration and virtual disk files. The VM
storage can either be an internal storage local to ESX or an external storage
that can be shared by multiple copies of ESX. Advanced features such as
VMotion, HA, and DRS require that the disk and configuration files are
stored on VMs external shared storage.
•
vSphere CLI
— Performs many operations that you can also perform using
the ESX 4 service console. vSphere CLI commands are especially useful for
an ESXi 4 host because it does not include a service console. vSphere CLI
commands can be used in scripts that run on ESXi 4 and ESX 4 hosts
located remotely.
