Installing Multiple PCIe Cards and Resolving Limited Resources

When a large number of PCIe add-on cards are installed in the server, the system may run out of the
following resources required for PCIe devices:
•
•
The topics in this section provide guidelines for resolving the issues related to these limited resources.
