I/O expansion
The SR650 server supports one LOM card slot and up to seven PCIe slots: one slot on the system planar that is
dedicated to an internal storage controller, one regular PCIe slot on the system planar, and up to five 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:
LOM card slot
Slot 1: PCIe 3.0 x16 or PCIe 3.0 x8; full-height, half-length (PCIe x16 slot is double-wide)
Slot 2: PCIe 3.0 x8; full-height, half-length (not present if the slot 1 is PCIe x16 or slot 3 is ML2 x16)
Slot 3: PCIe 3.0 x8, or ML2 x8, or ML2 x16; full-height, half-length
Slot 4: PCIe 3.0 x8; low profile (vertical slot on system planar)
Slot 5: PCIe 3.0 x16; full-height, half-length
