Hardware Requirements for Collector
Machines
Your VCM Collector hardware requirements depend on the number of physical and virtual managed
machines in your environment.
Use this information to determine how many machines you plan to manage. You can determine the
individual hardware requirements 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 vCenter Server instances, 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” 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 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. After you complete the worksheet and
determined the number of managed machines, size your Collector machine. Use the blank worksheet to
record the managed machines in your environment.
