PCIe Slot Characteristics

There are three external PCIe slots and one internal PCIe slot available in the Oracle Server X7-2. The external slots support optional, standard PCIe cards and are numbered 1, 2, and 3 from left to right when you view the server from the rear. The internal slot, which installs on the riser in PCIe slots 3 and 4, supports a required internal SAS controller HBA card. For a view of the back panel that shows PCIe slot numbering, see Back Panel Components and Cable Connections.


Note -  PCIe slot 1 is nonfunctional in single-processor systems.

Note -  All of the PCIe slots comply with the PCI Express 3.0 specification and can accommodate 25 Watt PCIe cards.
