– For systems with at least 64 GB of memory, but less than 128 GB of memory, slots are allocated 16
GB of DDW capability.
– For systems with at least 128 GB of memory, but less than 256GB of memory, slots are allocated 32
GB of DDW capability.
– For systems with 256 GB or more of memory, slots are allocated 64 GB of DDW capability.
Adapters placement rules
Use this information while selecting slots for installing adapters in the EMX0 PCIe3 expansion drawer
attached to the system. Use Table 11 on page 19 to identify slot placement priorities and the maximum
number of adapters that can be installed in the EMX0 PCIe3 expansion drawer based on the operating
system.
Note: You can click the link that appears in the feature code column for more technical information
specific to the adapter.
• If the EMX0 PCIe3 expansion drawer is configured with two PCIe3 6-slot fanout modules, distribute the
adapters across both I/O modules whenever possible.
• If FC EC46 is driving the internal DVD, it must be installed in the I/O expansion drawer that is closest to
the system. The system and IO expansion drawer must be in the same rack.
Note: If slot P1-C2 of the first node contains a controller adapter (CC), it must be the first option to
consider for wiring the module with the USB adapter driving the internal DVD. If it is a PCIe3 6-slot
fanout module, install FC EC46 in slot Px-C3 of the PCIe3 6-slot fanout module.
• Do not attempt to install x16 adapters in x8 slots. Doing so can damage the x16 connectors in the EMX0
PCIe3 expansion drawer.
