The memory requirements to support port processing also increase with
each new port. A fully configured system, with the maximum number of
ports (100), needs 600 MB of main memory. Hard disk requirements are
less than 40 MB.
Table 89 lists the theoretical maximum number of ports that typical
Pentium processors can manage.
The maximum number of ports can be limited by the number of licenses.
