Hardware Requirements for Collector
Machines
VCM hardware requirements are dependent on the number of physical and virtual machines within your
enterprise that 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
Determine 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. To determine your total number of managed machines, enter data for your
enterprise in the Sizing Worksheet.
Within VCM, the term “managed machines” indicates the servers and workstations that VCM manages,
and from which VCM collects data. However, if you are licensing VCM for Microsoft Active Directory
(AD), expand this definition to include AD objects that you plan to have in your environment within the
next 12 to 24 months. Use the formulas in the worksheets to determine how your AD objects will increase
your managed machine count and affect your final sizing requirements. Taking these considerations into
account now ensures that you will have adequate disk space to accommodate VCM now and in the
future.
After you complete the worksheet and determined the number of managed machines, you must size your
Collector machine. See "Identify Your Specific Hardware Requirements" on page 12 for more information.
