3.4.1
PCI Express*
The Intel
®
C600-A PCH provides up to eight PCI Express* Root Ports, supporting the PCI
Express* Base Specification, Revision 2.0. Each Root Port x1 lane supports up to 5 Gb/s
bandwidth in each direction (10 Gb/s concurrent). PCI Express* Root Ports 1-4 or Ports 5-8 can
independently be configured to support four x1s, two x2s, one x2 and two x1s, or one x4
port widths.
From PCH on Intel
®
Server Board S2600WP, PCIe Port8 x1 Gen2 is connected to BMC Gen1
Uplink.
Ports 1-4 are connected to Intel
®
I350 GbE NIC. The remaining PCIe Gen2 interconnect
(Port 5-7, 1 based numbering) are unused.
3.4.2
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.
The PCI Express Port 3A of Intel
®
Xeon
®
Processor E5-2600 and E5-2600 v2 Product Families
can be configured to be a transparent bridge or a NTB with x4/x8 link width and
Gen1/Gen2/Gen3 link speed. Also this NTB port could be attached to another NTB port or PCI
Express* Root Port on another subsystem. NTB supports three 64bit BARs as configuration
space or prefetchable memory windows that can access both 32bit and 64bit address space
through 64bit BARs.
There are three NTB supported configuration:
 NTB Port to NTB Port Based Connection (Back-to-Back)
 NTB Port to Root Port Based Connection - Symmetric Configuration. The NTB port on
the first system is connected to the root port of the second. The second system’s NTB
port is connected to the root port on the first system, making this a fully symmetric
configuration.
 NTB Port to Root Port Based Connection - Non-Symmetric Configuration. The root port
on the first system is connected to the NTB port of the second system. And it is not
necessary for the first system to be a of Intel
®
Xeon
®
Processor E5-2600 and E5-2600
v2 Product Families system.
