Appendix C: Capacity Planning : Network Capacity Planning
   
Network Capacity Planning
A vCloud also brings network capacity planning to the forefront. Providers must consider IP address, VLAN, and ephemeral port capacity. The following table describes what must be managed from a capacity perspective and its impact.
Table 10. Network Capacity Planning Items
Item to Manage
Impact
IP addresses
*Available IP addresses to be assigned in support of a dedicated external network for an organization, such as for Internet access or hardware-based firewall rules.
*Need to track IP addresses assigned to specific organizations to determine what is available for a shared external organization network.
VLANs
*VLANs available for VLAN-backed pool assignment, if required.
*VLANs available for vCloud Director Network Isolation transport networks, one per vCloud Director Network Isolation pool.
Expandable static port bindings
*Default vCloud Director network pool type.
*Overall number of static ports expands in increments of ten as needed. Note that unused but allocated static port bindings do not increase the total number of static port bindings available.
