System IO
The server board Input/Output features are provided via the embedded features and
functions of several onboard components including the Integrated I/O Module (IIO) of the
Intel® Xeon® E5-2600 v3 and v4 processors, the Intel® C612 series chipset, the Intel® Ethernet
controller I350 or X540, and the I/O controllers embedded within the Emulex* Pilot-III
Management Controller.
3.4.1
PCI Express* Support
The integrated I/O module incorporates the PCI Express* interface and supports up to 40
lanes of PCI Express. The Intel® Server Board S2600CW supports six PCIe slots from two
processors and PCH:
From PCH:
-
Slot 1: PCIe Gen II x4
From the first processor:
-
Slot 5: PCIe Gen III x16/x8 electrical with x16 physical connector. Electrical x16 for
S2600CW2R or S2600CWTR, electrical x8 for S2600CW2SR or S2600CWTSR
-
Slot 6 PCIe Gen III x16 electrical with x16 physical connector
From the second processor:
-
Slot 2: PCIe Gen III x16 electrical with x16 physical connector
-
Slot 3: PCIe Gen III x8 electrical with x8 physical connector
-
Slot 4: PCIe Gen III x16 electrical with x16 physical connector
The server board supports up to three full length full height double-width PCIe cards on slot
2, slot 4, and slot 6.
Standard PCIe slots can provide up to 25W power. PCIe slot 2, 4, and 6 can provide up to 75W
power. The higher power requirement needs direct power cables from power supplies.
Note:
1.
Both CPU power connectors need to be connected in order for all the PCIe slots to work
even only one CPU is installed.
2.
While PCIe slot 5 is also an x16 connector, only 3 x16 PCIe slots on the board can support
up to 75W slot power at a time. This is a configuration limitation based on the System
Power budget. When used as riser slot, slot 6 can each provide up to 75W power to the
riser.
Below is a list of possible power configurations supporting different high power PCIe cards:
x16 150W card
-
75W from PCIe slot and 75W from PSU direct cable attach: 75W (2x3 conn)
