Dynamic Ports On Demand (DPOD) IMPORTANT: The DPOD feature is applicable only to the SAN Switch model 4/12 (part number AE370A). This switch ships in a 12-port configuration, and is upgradeable to a 24-port configuration. DPOD automatically enables ports as they are physically cabled or in the case of a server blade when the server is powered on. The pre-existing Ports On Demand (POD) functionality was static, that is, a preset group of ports were individually enabled with POD licenses. In contrast, the new Dynamic POD functionality does not require predefined assignment of ports. With DPOD, the determining factor is the total number of ports in use and the number of purchased dynamic ports. The DPOD feature: • Automatically detects HBA connected server ports or cabled ports. • Assigns a POD license to each of these ports. This dynamic allocation of POD licenses is controlled with the licensePort command (see below). When the DPOD mechanism detects a server blade in an online state, it automatically assigns a POD license to the blade. The Dynamic POD mechanism detects which ports have active links and make license assignments to these ports. If the initial DPOD assignment does not exhaust the number of ports purchased, then new connections can be made at a later time not to exceed the total number of purchased dynamic ports. A port is connected when the Port Status LED indicates an online state. NOTE: DPOD does not consider disabled ports as candidates for license assignments. You can persistently disable an otherwise viable port to cause it not to come online and preserve a license assignment to be used by some other port. When DPOD is used in server blades that are embedded in a blade server enclosure, such as the Brocade 4Gb SAN Switch for HP c-Class BladeSystem, a port can be detected and assigned a POD license only if the server blade is installed with an HBA present. A server blade that does not have a functioning HBA will not be treated as an active link for the purpose of initial POD port assignment. Fabric OS 5.0.5b 7

Dynamic Ports On Demand (DPOD)
IMPORTANT:
The DPOD feature is applicable only to the SAN Switch model 4/12 (part number
AE370A). This switch ships in a 12–port configuration, and is upgradeable to a
24–port configuration.
DPOD automatically enables ports as they are physically cabled or in the case of a
server blade when the server is powered on. The pre-existing Ports On Demand (POD)
functionality was static, that is, a preset group of ports were individually enabled
with POD licenses. In contrast, the new Dynamic POD functionality does not require
predefined assignment of ports. With DPOD, the determining factor is the total number
of ports in use and the number of purchased dynamic ports.
The DPOD feature:
•
Automatically detects HBA connected server ports or cabled ports.
•
Assigns a POD license to each of these ports.
This dynamic allocation of POD licenses is controlled with the
licensePort
command
(see below). When the DPOD mechanism detects a server blade in an online state, it
automatically assigns a POD license to the blade.
The Dynamic POD mechanism detects which ports have active links and make license
assignments to these ports. If the initial DPOD assignment does not exhaust the number
of ports purchased, then new connections can be made at a later time not to exceed the
total number of purchased dynamic ports. A port is connected when the Port Status LED
indicates an online state.
NOTE:
DPOD does not consider disabled ports as candidates for license assignments. You
can persistently disable an otherwise viable port to cause it not to come online and
preserve a license assignment to be used by some other port.
When DPOD is used in server blades that are embedded in a blade server enclosure,
such as the Brocade 4Gb SAN Switch for HP c-Class BladeSystem, a port can be
detected and assigned a POD license only if the server blade is installed with an HBA
present. A server blade that does not have a functioning HBA will not be treated as an
active link for the purpose of initial POD port assignment.
