Introduction

VMware ESXi software is the next generation virtualization software that

comes integrated with Dell PowerEdge™ servers. By integrating VMware

virtualization, Dell has taken a major step toward simplifying deployment and

management of virtualized environments. Unlike traditional ESX Server,

ESXi Server does not have a service console, helping reduce the installation

footprint of the software and allowing the hypervisor to be directly installed

on the server’s internal flash storage. ESXi ships pre-installed on certain Dell

servers. No additional software installation is needed on the server for systems

management. With minimal configuration, users will be able to monitor and

manage their virtualization environment.

This document provides an overview of the systems management architecture

in VMware ESXi software on Dell PowerEdge systems. Detailed steps to

install and configure the server and tools to manage the server are provided,

including troubleshooting tips and known issues.

For more information on setting up ESXi with your Dell PowerEdge server,

refer to the VMware ESXi Dell Solutions Guide at support.dell.com. For

information on managing the virtualization environment, refer to the

VMware documentation at

www.vmware.com/support/pubs/vi_pages/vi_pubs_35_3i_e.html.

Overview

Common Information Model

To help reduce the system footprint and simplify deployment, ESXi does not

have a traditional service console management interface where Dell

OpenManage™ agents are installed. Instead, to provide the required hardware

manageability, VMware has incorporated standard Common Information

Model (CIM) management profiles into the virtualization software. The CIM

framework is an open standard that defines a framework on how managed

hardware elements in a server are represented. The CIM framework consists

of CIM providers developed by hardware vendors to enable monitoring and

managing of the hardware device. By representing the hardware elements

using standard CIM, ESX provides any management tool implementing the

6Systems Management Guide

same open standards the ability to manage the server. The hardware

management data is provided to management applications via CIM XML as

well as WSMAN.

VMware Infrastructure (VI) Client has been enhanced to provide hardware

health status of various hardware devices. VMware Infrastructure Client uses

CIM XML, a protocol to read hardware information provided by the CIM

providers. Each of the monitored hardware devices are listed along with the

health status. Future Dell Systems Management applications will make use of

WSMAN for hardware management on ESXi.

Simple Network Management Protocol

In addition to CIM, hardware health alerts are available through standard

Simple Network Management Protocol (SNMP) traps. Administrators may

now monitor and manage the hardware through any management application

that supports any of these standard protocols. Dell OpenManage IT Assistant

may be used to monitor the PowerEdge servers running ESXi through SNMP.

VMware has developed remote command line (RCLI) tool to configure the

SNMP agent in ESXi. This tool is available for download for Windows, Linux

and also as a Virtual Appliance. The RCLI tool can be downloaded from the

VMware website at www.vmware.com/download/vi/drivers_tools.html.

Remote Management

PowerEdge servers may also be remotely managed through the Dell Baseboard

Management Controller (BMC) and Dell Remote Access Controller

(DRAC). Both BMC and DRAC use the Intelligent Platform Management

Interface (IPMI) for out-of-band remote access. The BMC can be accessed by

using the BMC Management Utilities (BMU), a collection of software

applications that enable remote management of Dell systems equipped with

a BMC. BMU include the following components: IPMItool with Dell

extensions, IPMI Shell, and Serial-Over-LAN Proxy (SOL Proxy). IPMItool is

a CLI utility that helps in configuring and managing devices using the IPMI

version 1.5 and later. IPMItool supports out-of-band (OOB) remote access

(over a LAN or through the serial port) to a single system at a time. DRAC

can be accessed via its web served GUI as well as SSH and the racadm

command line interface. IT Assistant can be utilized in conjunction with the

Systems Management Guide 7

BMC’s IPMI over LAN interface for limited network discovery and health

monitoring. Its event console can also receive and act upon SNMP Platform

Event Traps (PETs) that are generated by the BMC.

Figure 1-1. Systems Management Overview With VMware ESXi

The following table lists the common use cases in systems management and

the tools used to perform the task:

Use Case Tools Needed

Deployment and

Configuration

VMware ESXi comes pre-installed on Dell PowerEdge servers.

There is no need to utilize the System Build and Update Utility

(SBUU) to install ESXi. Note that the SBUU does not create or

install Virtual Machine (VM) images.

The Dell Deployment Toolkit (DTK) and SBUU may be used to

configure the BIOS, storage, and DRAC prior to booting into

ESXi. The server can also be configured at boot time by pressing

<F2> to enter BIOS setup, <Ctrl><M> to configure the RAID

controller, and <Ctrl><E> to configure the BMC/DRAC

features.

8Systems Management Guide

NOTE: Each of these use cases and various operations for these use cases are

explained in detail in "Systems Management Use Cases" on page 11.

Install and Configure Systems Management

Components

First Boot Setup and Configuration

VMware ESXi comes pre-installed on supported Dell PowerEdge servers. For

steps to setup and configure ESXi on PowerEdge server, refer to VMware ESXi

Dell Solutions Guide at support.dell.com. Make sure that the DRAC is

configured as per the steps in the document.

Health

Monitoring

VI Client may be used to monitor the health information of

various hardware components. IT Assistant, DRAC, and the BMU

can also be used for limited health monitoring.

Alert Monitoring The event console feature of IT Assistant may be used to monitor

hardware and virtual machine traps generated from ESXi as well

as SNMP Platform Event Traps generated by the BMC.

Change

Management

SBUU may be used to update the BIOS and firmware of the PE

server. SBUU does not support updating of device drivers for ESXi

or virtual machines.

VMware update manager is used to update the ESXi image

which could contain updated device drivers for the system.

Troubleshooting,

Logging, and

Diagnostics

The system log and management agent log may be retrieved using

VI Client or may be viewed from the terminal.

The BMC System Event Log (SEL) is available using DRAC, IT

Assistant, or the BMU.

Diagnostics can be performed using Dell offline diagnostics tools.

Remote

Management

Dell Remote Access Controller (DRAC) provides lights out

remote management functionality.

Use Case Tools Needed

Systems Management Guide 9

Management Station Setup

The Management Station is the system from which one or more systems

running ESXi will be managed. The management station can also be used to

manage systems not running ESXi. The management station is required to

support some but not all of the identified use cases, and typically contains the

following set of management tools:

• IT Assistant

• Baseboard Management Utilities

• VMware Infrastructure Remote Command Line Interface (RCLI)

•

VMware Infrastructure

Client

• VMware VirtualCenter Server (optional)

Based on number of systems and devices to be managed and the hardware

configuration of the management station, it may be desirable to install IT

Assistant and VirtualCenter Server on separate systems. Figure 1-2 shows the

various components required to manage ESXi on PowerEdge Servers.

ESXi Software Configuration

ESXi must be configured to enable monitoring of the server using SNMP. To

configure SNMP in ESXi:

Configure the SNMP settings in ESX Server by using VMware RCLI. The

following commands must be executed from the server where VMware

RCLI is installed:

Configure the SNMP setting using the following command:

vicfg-snmp --server <ESX_IP_Address> --username

root --password <password> -c <community_name>

-t <ITAIP>@162/<community_name>

Enable SNMP using the following command:

vicfg-snmp --server <ESX_IP_Address> --username

root --password <password> -E

To view the SNMP configuration, execute the following command:

vicfg-snmp --server <ESX_IP_Address> --username

root --password <password> -s

Perform discovery and inventory of the server using IT Assistant.

Perform discovery and inventory of the ESX server system interface

using SNMP

Perform discovery and inventory of the DRAC interface using IPMI.

For more information, refer to the

IT Assistant User Guide

www.support.dell.com/support/edocs/software/smitasst/

Once discovered, the ESX server is ready to be monitored using IT

Assistant. SNMP traps from the ESX server can be received in IT Assistant.
