Intel® Server Board S2600CP Functional Architecture
4.2.3

Processor Integrated I/O Module (IIO)

The processor's integrated I/O module provides features traditionally supported through chipset
components. The integrated I/O module provides the following features:
4.2.3.1.1 PCI Express Interfaces
The integrated I/O module incorporates the PCI Express interface and supports up to 40 lanes
of PCI Express. Intel
From first processor:

o Slot 1: PCIe Gen III x4/x8 electrical with x8 physical connector
o Slot 2: PCIe Gen III x8 electrical with x8 physical connector
o Slot 3: PCIe Gen III x8 electrical with x8 open-ended physical connector
o Slot 4: PCIe Gen III x8 electrical with x8 physical connector
o Slot 6: PCIe Gen III x8 electrical with x16 connector, support riser card.
From second processor:

o Slot 5: PCIe Gen III x8 electrical with x8 open-ended physical connector
Note: PCIe slot 5 is functional only when the second processor is installed.
4.2.3.1.2 DMI2 Interface to the PCH
The platform requires an interface to the legacy Southbridge (PCH) which provides basic,
legacy functions required for the server platform and operating systems. Since only one PCH is
required and allowed for the system, any sockets which do not connect to PCH would use this
port as a standard x4 PCI Express 2.0 interface.
4.2.3.1.3 Integrated IOAPIC
Provides support for PCI Express devices implementing legacy interrupt messages without
interrupt sharing.
4.2.3.1.4 Intel
