<title>Setting Zone VLAN and Running VM Maximums</title>
|
|
<para>In the external networking case, every VM in a zone must have a unique guest IP address.
|
|
There are two variables that you need to consider in determining how to configure &PRODUCT;
|
|
to support this: how many Zone VLANs do you expect to have and how many VMs do you expect to
|
|
have running in the Zone at any one time.</para>
|
|
<para>Use the following table to determine how to configure &PRODUCT; for your
|
|
deployment.</para>
