Intel® Server Board S2600CP Functional Architecture Intel® Server Board S2600CP and Server System P4000CP TPS 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® Server Board S2600CP supports 6 PCI-e slots from two processors:  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® QuickData Technology Used for efficient, high bandwidth data movement between two locations in memory or from memory to I/O. 4.3 Intel® C600 Chipset Functional Overview The following sub-sections will provide an overview of the key features and functions of the Intel® C600-A chipset used on the server board. 38 Revision 1.2 Intel order number G26942-003
