Slots P1-C1 and P2-C1 inherit the I/O Adapter Enlarged Capacity attribute from the slot in the system
that connects to the EMX0 PCIe3 expansion drawer.
Notes:
• All slots are PCIe3 slots.
• All slots support full-length, full-height adapters or short form-factor with a full-height tailstock in
single-wide, generation 3, blind-swap cassettes.
• Slots C1 and C4 in each PCIe3 6-slot fanout module are PCIe3 x16 buses and slots C2, C3, C5, and C6
are PCIe x8 buses.
• All slots support enhanced error handling (EEH).
• All PCIe slots are hot swappable and can be serviced with the power on.
• All six adapters in a PCIe3 6-slot fanout module can be in SR-IOV shared mode.
• If you have a CCIN 50CB PCIe3 6-slot fanout module, the FC EC2S and FC EC2U adapters are only
supported in slots C2 and C5. If you have a CCIN 50CD PCIe3 6-slot fanout module, the FC EC2S and FC
EC2U adapters are supported in slots C1 through C6, but only four FC EC2S and FC EC2U adapters can
be in SR-IOV mode at a time.
Firmware slot capabilities
System PCIe slots are allocated direct memory access (DMA) space using the following algorithm:
• All slots are allocated a 2 GB default DMA window.
• Slots P1-C1 and P2-C1 inherit the I/O Adapter Enlarged Capacity attribute from the slot in the system
that connects to the EMX0 PCIe3 expansion drawer.
• All other I/O adapter slots are allocated Dynamic DMA Window (DDW) capability based on installed
platform memory. DDW capability is calculated assuming 4K I/O mappings:
– For systems with less than 64 GB of memory, slots are allocated no DDW capability.
