PA-5400 Series Firewall Data Processor Card
(DPC)
The PA-5400 Series Data Processor Card (DPC) is a front slot card that improves the processing capacity of
the firewall. You can install up to four or five DPCs depending on your scaling needs and slot configuration.
A DPC can be installed in slots 2 through 6; however, slot 2 may also be used for the installation of a
PA-5400 Series Firewall Networking Card (NC)
The PA-5450 firewall makes use of paired
in order to direct processing
power from a DPC to a corresponding Networking Card (NC). Certain commands issued to
the NC affect or are affected by the status of its corresponding DPC.
Because the DPC has no front ports or interfaces, you must change the firewall’s session distribution policy
from the default.
It is recommended that you change the session distribution policy to session-load when
installing the DPC.
The following DPCs can be installed in a PA-5400 Series firewall:
•
PA-5400 DPC-A
The PA-5400 DPC-A improves session capacity and performance through additional data plane instances.
