The single-server topology is suitable for small to
medium, single-site enterprises. This topology facilitates administration
by a single administrator, but does not preclude the creation of
additional administrator accounts as required by your Administration
plan.
However, this arrangement concentrates the burden of network
traffic (agent polling, data transfer, update deployment, and so
on) on a single server, and the LAN that hosts it. As your network
grows, the impact on performance also increases.
