With Brocade's Dynamic Ports on Demand (DPOD) feature, ports are licensed in one of two methods: as
they come online or as selected by the administrator. With the 16 Gb SAN switch, the first 12 ports
reporting (on a first-come, first-served basis) on boot-up are assigned licenses. These 12 ports can be
any combination of external or internal Fibre Channel (FC) ports. After all port licenses have been
assigned, you can manually move those licenses from one port to another. Because this is dynamic, no
defined ports are reserved except ports 0 and 29. The 24-port 16 Gb SAN switches have the same
behavior; the only difference is the number of ports, which is 24.
Table 5 shows the total number of port licenses on the switch after applying compatible port upgrades.
Note: A maximum of one upgrade of each type (one Upgrade 1 and one Upgrade 2) is supported per one
switch module. Upgrade 1 and Upgrade 2 can be applied independently of each other.

* With the dual-port FC adapters installed in compute nodes, up to 34 ports (14 internal, 20 external) can be utilized.
The remaining 14 internal ports require use of the 4-port FC adapters in the server's ITE.
