This server has six PCIe 3.0 slots on the rear panel that accommodate low-profile PCIe cards. All slots support x8 PCIe cards and slots 2 and 5 can support x8 PCIe cards with physical x16 connectors. There is a seventh PCIe slot on the motherboard for an HBA or PCIe switch card.
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 S7-2 Series Servers Product Notes and the documentation for each card to determine if there are slot requirements.
For example, on the server supporting twelve NVMe drives, the three PCIe switch cards must be in slots 1, 3, and 7.
Cards with physical x16 connectors can only be in slots 2 and 5.
