Technical Product Specification
Intel® Server Board S2600CO Family TPS Functional Architecture Overview
Revision 1.6 31
Intel order number G42278-004
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.
Integrated IOAPIC: Provides support for PCI Express* devices implementing legacy
interrupt messages without interrupt sharing
Non Transparent Bridge: PCI Express* non-transparent bridge (NTB) acts as a
gateway that enables high performance, low overhead communication between two
intelligent subsystems; the local and the remote subsystems. The NTB allows a local
processor to independently configure and control the local subsystem, provides isolation
of the local host memory domain from the remote host memory domain while enabling
status and data exchange between the two domains.
