reduces the potential for performance issues. Once the operating conditions have
been monitored, the decision to provide more capacity and more users can be
considered.
A virtual terminal server is defined as a Windows 2008 R2 virtual machine.
Windows, VMware Tools, Third party software, and 800xA are installed.
Table 9 provides an example to the concept of defining the virtual machine that the
virtual terminal serve is to run in based on the expected number of concurrent users.
Note that, based on the level of loading that the user session creates, it is possible to
have more or less users per terminal server. As this is a factor of what the users are
doing, and the CPU speed of the physical server, this cannot be accurately
determined beforehand. This table provides an example for the dimensioning of a
virtual terminal server based on the number of concurrent users.

There are many factors involved in providing adequate physical computer resources
for the virtual environment. The physical server supports other 800xA virtual nodes.
When specifying physical hardware, the requirements of all virtual nodes are
