Assigned PCIe slot order when the I/O Adapter Enlarged Capacity option is enabled. For example, if the option was enabled with a value of 5, ve slots are enabled with the I/O enlarged capacity.
Note: Enabling the I/O Adapter Enlarged Capacity option will only affect Linux
®
partitions. If your system does not have Linux partitions, the I/O Adapter Enlarged Capacity setting should be disabled.
Note the following:
• The I/O cassettes that are used in the 9040-MR9 system can hold half length, full height and half length, half height PCIe adapters.
• All PCIe slots support the single root I/O virtualization (SR-IOV) function.
