PCIe Card Configuration

Note -
the documentation for each PCIe card for detailed information about known issues and
configuration limitations.
This server has eight PCI Express 3.0 slots that accommodate low-profile PCIe cards. All slots
support x8 PCIe cards. Four slots are also capable of supporting x16 PCIe cards:
All Slots – x8 electrical interface
■
Slots 1, 2, 7 and 8 – x16 electrical interface
■
To determine the slot in which to install a PCIe card, follow these guidelines:
1. Install cards that require a specific slot. Refer to the SPARC T8-2 Server Product Notes and
the documentation for each card to determine if there are slot requirements.
2. Install the first NMVe switch card in slot 1. Install a second NMVe switch card in slot 2.
3. Install the remaining cards so that the load on the server is balanced.
In general, install the biggest and hottest cards in the outside slots and work your way to the
middle, alternating sides to evenly distribute cooling.

Before installing PCIe cards, refer to the SPARC T8-2 Server Product Notes and
Fill the PCIe slots in this sequence: 8, 1, 7, 2, 6, 3, 5, 4.
Place the cards in this order: Expansion cards, storage cards, network cards, other cards.
