Achieving a Successful VCMInstallation

Perform the requirements to successfully install VMware vCenter Configuration Manager (VCM), and then install VCM in any of the supported single-tier, two-tier, or three-tier installation configurations.

Determine your specific hardware and software requirements for VMware vCenter Configuration Manager (VCM). Perform the preparatory steps to install and configure your physical and virtual machines for a successful VCM installation.

To determine your hardware and software requirements, begin by answering several questions.

How many vCenter Server, UNIX, Linux, and Windows servers and workstations will you license?

How often will you collect data?

How much data will you collect?

How long will you retain the collected data and change data?

What additional VCM components will you use? For available VCM components, see the Download VMware vCenter Configuration Manager Web site.

Do you understand the VCM security requirements? See the VCM Security Guide.

To achieve a successful VCM installation, you must understand the hardware and software requirements for VCM Collector machines and VCM managed machines, prepare your environment for VCM installation, then install VCM.

Before you install VCM, use the following chapters to prepare for VCM installation. Perform the prerequisite steps and procedures in the order presented, configure resources, configure your installation environment, then install VCM.

After you install VCM, set the file growth for your VCMdatabase, then create a maintenance plan.

VCM Collector and Agent OS Platform Support

All Agent and Collector OS platform support is specific to versions and editions indicated in the supported platforms table. Some configurations can reduce or block the performance or functionality of VCM components, such as configurations by vendors, third-party, custom lock downs, endpoint security products, policies, and restricted system. Troubleshooting and support of VCM components in lockeddown or reconfigured environments is not included under the standard product maintenance agreement. Support in these environments is available through an additional Professional Services engagement.

All testing is performed in a hardened environment, as documented in the VCM Security Guide. Testing with OS vendor hardening applied for the VCM Collector is part of the supported configurations.

VMware, Inc.

vCenter Configuration Manager Advanced Installation Guide

For details about VCM Collector machines, see Hardware Requirements for Collector Machines and Software and Operating System Requirements for Collector Machines in the VCM Installation Guide.

For details about VCM managed machines, see Hardware and Operating System Requirements for Managed Machines in the VCM Installation Guide.

VMware, Inc.

Hardware Requirements for Collector Machines

Your VCM Collector hardware requirements depend on the number of physical and virtual managed machines in your environment.

Disk space requirements vary based on the following factors.

Number of machines from which you collect data

Type of data collected and filters used

Frequency of collections

Data retention

Determine the Size of Your Environment

In VCM, the term “managed machines” refers to the servers and workstations that VCM manages, and from which VCM collects data. If you use VCM for Microsoft Active Directory (AD), this total should also include AD objects that you plan to have in your environment in the next 12 to 24 months.

VCM hardware requirements are recommended based on whether your environment contains 1–1000, 1001–2000, 2001–5000, or more managed machines. To determine the number of managed machines on which to base your collector size, consider the number of vCenter Server instances, Windows servers and workstations, Linux or UNIX machines, and virtual machines that you are licensing. Identify any other VCM components that you are licensing.

VMware, Inc.

To determine your total number of managed machines, enter data for your enterprise in the sizing worksheet. In the following example, an enterprise environment contains machines and objects that represent 1377 managed machines.

Total Managed Machines:

Identify Your Specific Hardware Requirements

Size your VCM Collector and database based on the requirements for managed vCenter Server instances and the number of machines managed by VCM.

Database Sizing for Managed vCenter Server Instances

Use the following requirements to size your SQLServer database depending on the number of hosts and guests per vCenter Server managed by VCM. Guest collections include only the virtual machine data that vCenter provides and do not include any in-guest data. In-guest collections are separate from vCenter collections.

VMware, Inc.

Hardware Requirements for Collector Machines

These requirements are in addition to the base VCM storage requirements, and are based on an estimated 10% data change per day times 15 days of data retention.

Table 2–3. VCMDatabase Sizing per vCenter Server Instance

Host s Guests Est. Daily Ch ange Data Retent ion in Days Data Size

25 250 10% 15 3GB

50 500 10% 15 6GB

250 2500 10% 15 30GB

The best practice in production environments is to have the Managing Agent process requests for a single vCenter Server. Dedicate one Managing Agent machine for each vCenter Server. In a single vCenter Server instance environment, the VCM Collector can be the Managing Agent.

A single Managing Agent can manage multiple vCenter Server instances depending on your collection schedules and when potential job latency is not an issue, such as when a single Managing Agent must process multiple requests serially. A single Managing Agent can manage multiple vCenter Server instances as long as only one vCenter Server is collected at a time.

When job latency is not a problem, and depending on your collection schedules, you might dedicate a single Managing Agent for every five vCenter Server instances or 100 hosts. You could dedicate one Managing Agent to a vCenter Server that manages 100 hosts, or a collection of four vCenter Server instances that each manage 10 hosts could share a Managing Agent.

Hardware and Disk Requirements By Number of Managed Machines

Use the Minimum Hardware Requirements and Minimum Disk Configuration Requirements tables to determine your hardware and disk configuration requirements for a single-tier server installation.

Use the total number of managed machines from the Sizing Worksheet to locate your environment size (1–1000, 1000–2000, 2000–5000, or more). If you have more than 5000 machines in your environment, contact VMware Technical Support to help you determine your hardware requirements.

If you run SQLServer on a virtual machine, see Microsoft SQL Server on VMware Best Practices Guide at

http://www.vmware.com/files/pdf/sql_server_best_practices_guide.pdf. If you run SQL Server in a Hyper-

V environment, see Best Practices and Performance Considerations for Running SQL Server 2008 in a Hyper-V Environment on the Microsoft Web site.

The requirements listed in the following tables are based on the following assumptions.

Daily VCM collections using the default filter set with additional Microsoft AD security descriptors collected using VCM for AD.

15 days retention of change data.

Simple recovery mode only.

Daily VCM Patching collections.

No applications other than VCM are running on your server.

VCM for AD collections cause the TempDB database to grow significantly. If you have a fully populated Microsoft Active Directory and plan to perform frequent AD collections, increase your hardware requirements.

VMware, Inc.

Longer data retention, additional WMI, registry filters, and custom information collections also add to the requirements.

vCenter Configuration Manager Advanced Installation Guide

Software Installation and Configuration Overview

VCM supports the Collector running on a Windows Server 2008 R2 operating system. Complete the preparatory steps to prepare your Windows Server 2008 R2 machine for a successful VCM installation. When you use VCM Installation Manager to install VCM, the system checks will run without error, indicating that you have met all of the requirements to install VCM.

VCM supports several installation configurations including single-tier, two-tier, and three-tier. You use Installation Manager to install VCM in these configurations.See "Preparing for Installation" on page 19.

To understand the requirements to upgrade or migrate your environment to the latest version of VCM, see "Upgrading or Migrating VCM" on page 129.

VMware, Inc.

Preparing for Installation

Prepare your environment for a VCMinstallation by performing the prerequisites to include hardware, software, and physical and virtual machines before you install VCM components and tools.

VCM Installation Configurations

VCM supports several installation configurations including single-tier, two-tier, and three-tier. Use Installation Manager to install VCM in these configurations.

Single-Tier Server Installation

In a single-tier server installation, the VCM database server, Web server, and the VCM Collector components reside on a single Windows Server 2008 R2 machine, which is referred to as the VCM Collector. The installation installs all of the core VCM components, including the databases, console, and services. This configuration enables integrated security by default.

Two-Tier Split Installation

In a two-tier split installation, the VCM database resides on the Windows Server 2008 R2 database server machine, and the VCM Collector and Web components reside on the second Windows Server 2008 R2 machine.

Three-Tier Split Installation

In a three-tier split installation, the VCM databases, the Web applications, and the VCM Collector components reside on three different Windows Server 2008 R2 machines.

To perform the prerequisite steps for VCM installation, see "System Prerequisites to Install VCM" on page

21.

VMware, Inc.

vCenter Configuration Manager Advanced Installation Guide

VMware, Inc.

System Prerequisites to Install VCM

Perform the system prerequisites to prepare your physical or virtual machine for VCM installation. The prerequisites ensure that your machine meets the requirements for your environment to support a successful VCM installation.

After you perform the system prerequisites, during VCM installation the Installation Manager runs system checks on the database server, Web server, and VCM Collector machine in your installation configuration. These system checks verify that you have satisfied all of the prerequisites for a successful VCM installation. During the system checks, Foundation Checker verifies component-specific issues against VCM, captures common issues, and identifies any problems with the version of VCM being installed.

Foundation Checker might generate warnings, which you must review. In some cases, you might need to resolve the warnings before you install VCM, even though the warnings will not prevent you from starting the installation.

If Foundation Checker generates errors, you must resolve them before you install VCM. For more information about Foundation Checker, see the VCM Foundation Checker User's Guide.

Use the following topics to verify your system requirements.

Verify that your environment meets the security requirements. See the VCM Security Guide.

"Establish Local Administration Rights" on the next page

Verify that the user account of the person who performs the VCM installation, upgrade, or migration has all of the required rights.

"Verify Browser Compatibility" on the next page

Verify that the target VCM Collector machine, and any other machines that will access the VCM Web console interface on the VCM Collector, have a compatible Web browser installed.

"Verify the Default Network Authority Account" on the next page

Define the network authority account in the Local Administrators group on the Collector machine before you install VCM. The network authority account must be a domain account. VCM uses the default network authority account to collect data from Windows Agent machines.

"Specify the Collector Services Account" on page 23

Specify the Collector Service account to use during VCM installation. The account can be a system administrator account and must exist in the Local Administrators group on the Collector machine. The account must not be the Local System account.

"Verify the VCM Agent is Not Installed" on page 24

VMware, Inc.

vCenter Configuration Manager Advanced Installation Guide

The target Windows machine must not have a VCM Agent installed before you install VCM. If an Agent is installed, you must uninstall the Agent for VCM to install.

"Verify the SQLXML Version" on page 25

SQLXML provides client-side XML functionality and enhancements to existing SQL features. Verify that the correct version is installed.

Establish Local Administration Rights

Verify that the user account of the person who performs the VCM installation, upgrade, or migration has all of the required rights.

The following rights are required.

System administrator on the machines on which the installation or upgrade is performed.

System administrator on the database instance to be used.

Member of a domain.

The installing user account should not be the account used for VCM services, because the login of the VCM service account is disabled during installation.

After installation, do not create a VCM user that uses the SQL Server services account credentials.

What to do next

Verify the compatibility of your browser. See "Verify Browser Compatibility" below.

Verify Browser Compatibility

Verify that the target VCM Collector machine, and any other machines that will access the VCM Web console interface on the VCM Collector, have a compatible Web browser installed.

VCM supports the following browsers.

Internet Explorer version 8 and 9.

Internet Explorer version 10 in compatibility mode.

Mozilla Firefox version 6.0 or later with the Internet Explorer IE Tab add-on. This add-on requires Internet Explorer 6.0 to be installed on the machine.

What to do next

Verify the default Network Authority account. See "Verify the Default Network Authority Account"

below.

Verify the Default Network Authority Account

You specify the default network authority account during VCM installation. The default network authority account can be a system administrator account, such as a Domain Admin in the Local Admin Group.

VMware, Inc.

System Prerequisites to Install VCM

It is acceptable, but not preferred, to use the same account for the Collector, VCM Remote, vSphere Client VCM Plug-in, and Tomcat service accounts. If you use a single account, the permissions required for the Collector service account are sufficient. The account must be a local administrator, should not be a domain administrator, has bulk-insert permissions in SQL, and is a dbo of the VCM databases. In general, the Default Network Authority should be a different account, possibly a Domain Administrator with rights on more systems in the environment.

Procedure

1. On the Collector, right-click Computer and select Manage to open Server Manager.

2. Expand Configuration, expand Local Users and Groups, and click Groups.

3. Double-click Administrators and verify that the network authority account is listed as a member of the

Administrators group.

If the user or administrator’s group is not listed, add the user or group to the list. Verify that the user has Windows administrator rights issued by the network administrator.

To change the network authority account after installing VCM, click Administration and select Settings > Network Authority.

What to do next

Keep Server Manager open to specify the Collector Services account. See "Specify the Collector Services

Account" below.

Specify the Collector Services Account

Logging in to VCM using a service account can lead to unexpected or inconsistent behavior. Services that use the same account as a logged in user might modify the logged in user's current role or the machine group, or log the user out of the system.

If the password for the account changes, you must change the password in the Services Management console and the Component Services DCOM Config console.

Procedure

1. In Server Manager, verify that the Groups menu is open.

If not, expand Configuration, expand Local Users and Groups, and click Groups.

2. Double-click Administrators and verify that the account used for Collector Services is listed as a

member of the Administrators group.

If the user or administrator’s group is not listed, to ensure that the user has Windows administrator rights issued by the network administrator, add the user or group to the list.

What to do next

Verify that the VCM Agent is not installed on the Collector machine. See "Verify the VCM Agent is Not

Installed" on the next page.

Verify the VCM Agent is Not Installed

The VCM Collector installation includes an updated Agent. The target Windows machine must not have a VCM Agent installed before you install VCM. If an Agent is installed, you must uninstall the Agent for VCM to install.

Procedure

1. To determine whether a VCM Agent is installed on the Windows machine, verify whether the following folder exists.

%windir%\CMAgent

The %windir% environment variable specifies the directory where Windows is installed. This folder is the default location. The Agent installation directory is accessible in the registry at the following location.

HKLM\Software\Configuresoft\ECM\4.0\Common\PathsRootDir

2. If a VCM Agent is installed, remove the Agent from the target Windows machine.

a. If a working VCM Collector exists, use the VCM Web console to unlicense this machine and

remove the VCM Agent.

b. If a working VCM Collector does not exist, uninstall the Agent manually.

3. To uninstall the Agent manually, determine if the Agent was installed using the MSI installer.

a. Search for the string CMAgent under the following registry key.

HKEY_LOCAL_

MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

If an Uninstall registry subkey exists that has a GUID-named key and reference to the VCM Agent, such as {7C51E2CA-C932-44EF-8B77-3C03356A24CC}, the VCM Agent was installed using the MSI Installer.

b. Examine the uninstall data to confirm that this is the VCM Agent.

c. Open the setting UninstallString and copy the value.

An example value is as follows.

MsiExec.exe /X{7C51E2CA-C932-44EF-8B77-3C03356A24CC}

d. If an Uninstall GUIDregistry key that references the VCM Agent does not exist, the Agent was

installed using the manual installer.

4. Uninstall the VCM Agent.

a. If the Agent was installed using the MSI installer, to uninstall the Agent click Start and click Run to

execute the command line using the UninstallString registry value.

An example value is as follows.

MsiExec.exe /X{7C51E2CA-C932-44EF-8B77-3C03356A24CC}.

b. If the Agent was installed using the manual installer, run the following command to uninstall the

Agent.

%windir%\CMAgent\Uninstall\Packages\CMAgentInstall\UnCMAgentInstall.exe /S

Configure Resources to Install VCM on a Virtual Machine

To install VCM on a virtual machine, you must prepare the virtual machine to be used as a VCM Collector. Because VCM can place heavy workloads on the database, you must understand your environment workloads to determine the resource requirements.

For the VCM Collector to operate properly on a virtual machine, the virtual machine must satisfy several prerequisites to run SQL Server on a VMware virtual machine.You should provision the VCM virtual machine similar to a high throughput OLTP database application.

Use these guidelines to install VCM in development, test, or IT environments. For large scale environments, you might need to alter the requirements.

IMPORTANT Do not install VCM on a virtual machine on an ESX server that has over-allocated resources.

Prerequisites

Follow the requirements for physical hardware.See the VCM Installation Guide.

Perform the system prerequisite tasks. See the VCM Installation Guide.

Follow the best practices to install SQLServer. See the Microsoft SQL Server on VMware Best Practices Guide available on the VMware Web site at http://www.vmware.com.
