Hardware Requirements for Collector
Machines
VCM hardware requirements depend on the number of physical and virtual machines in your enterprise
that you plan to license for use with VCM. Use this information to determine how many machines you
plan to manage and the VCM components you plan to license. After you have this information, you can
determine the individual hardware requirements that you must satisfy to ensure a successful VCM
installation.
Disk space requirements vary based on the following factors.
n
Number of machines from which you collect 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 environment contains 1–1000,
1000–2000, 2000–5000, 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 or
Linux machines, and virtual machines that you are licensing. 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.
In VCM, the term “managed machines” indicates the servers and workstations that VCM manages, and
from which VCM collects data. If you are licensing VCM for Microsoft Active Directory (AD), this
definition includes AD objects that you plan to have in your environment in 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.
