Hardware Requirements -- Collector
Machines
Your VCM hardware requirements are directly dependent on the number of physical and virtual
machines within your enterprise you plan to license for use with VCM. Use the information in this chapter
to determine how many machines you plan to manage and what VCM components you plan to license.
Once you have this information, you will be able to continue using this chapter to determine the individual
hardware requirements that you must satisfy in order to ensure a successful VCM installation.
Disk space requirements vary based on:
n
Number of machines from which you are collecting data
n
Type of data collected and filters used
n
Frequency of collections
n
Data retention
Determining the Size of Your Environment
VCM hardware requirements are recommended based on whether your enterprise contains 1 to 1,000,
1,000 to 2,000, 2,000 to 5,000, or more managed machines. To determine the number of managed machines
on which to base your collector size, consider the number of Windows (servers and workstations),
UNIX/Linux, and virtual machines that you are licensing. In addition, identify any other VCM components
that you are licensing. Populate the worksheet in this section with your enterprise-specific data to
determine your total number of managed machines.
The following charts are designed to help you determine your sizing requirements for installing VCM.
Within VCM, the term “managed machines” is used to identify the servers and workstations from which
VCM collects data and manages. However, for the purposes of sizing your environment, it is necessary to
expand this definition to account for the Microsoft Active Directory (AD) objects (if you are licensing VCM
for AD) that you anticipate having in your environment within the next 12 to 24 months. Use the formulas
within the following worksheets to determine how your AD objects will increase your ’managed machine’
count, and thereby affect your final sizing requirements. By taking these considerations into account now,
you will be sure to have adequate disk space to accommodate VCM both now and in the future.
Once you have completed the following worksheet and determined the number of managed machines,
you will need to size your Collector machine. See "Identifying Your Specific Hardware Requirements" on
page 12 for more information.
