I/O expansion options
The server supports up to nine PCIe slots: one slot on the system planar that is dedicated for an internal
RAID controller, two regular PCIe slots on the system planar, and up to six PCIe slots with different riser
cards installed into two riser sockets on the system planar (one riser socket supports installation of one
riser card). The slot form factors are as follows:
Slot 0: PCIe 3.0 x8 (dedicated for an internal RAID controller)
Slot 1: PCIe 3.0 x16 or PCIe 3.0 x8; full-height, full-length (PCIe x16 slot is double-wide)
Slot 2: PCIe 3.0 x8; full-height, full-length (not present if the slot 1 is PCIe x16)
Slot 3: PCIe 3.0 x8 or ML2; full-height, half-length
Slot 4: PCIe 3.0 x8; low profile (vertical slot on system planar)
Slot 5: PCIe 3.0 x16; low profile (vertical slot on system planar)
Slot 6: PCIe 3.0 x16 or PCIe 3.0 x8; full-height, full-length (PCIe x16 slot is double-wide)
Slot 7: PCIe 3.0 x8; full-height, full-length (not present if the slot 6 is PCIe x16)
Slot 8: PCIe 3.0 x8; full-height, half-length
Note:
Slots 5, 6, 7, and 8 require the second processor to be installed.
The locations of the PCIe slots are shown in Figure 7.
