This server has six PCIe 3.0 slots that accommodate low-profile PCIe cards. All slots support x8 PCIe cards and two slots can support x16 PCIe cards.
To determine the slot in which to install a PCIe card, follow these guidelines:
Install cards that require a specific slot. Refer to the SPARC T7-1 Server Product Notes and the documentation for each card to determine if there are slot requirements.
The switch card supporting NVMe drives must be in slot 3, because of cable lengths.
x16 cards can only be in slots 3 and 4.
If a x16 card is in slot 3, any card in slot 2 is ignored.
If a x16 card is in slot 4, any card in slot 5 is ignored.
