steppings. A stepping is a version of the processor that is associated with a set of fixes and errata.

When mixing processors or processor steppings, observe the following rules:

•Each processor board (or each cell) supports only one processor family.

•All processors in a partition must be the same frequency and have the same amount of cache.

Processor Voltage Regulator Modules

The processor board contains voltage regulator modules that convert the 12-volt DC from the power supplies to the voltage required by the processors.

Node Controller

The node controller provides scalability, native PCIe, and fully buffered DIMM memory for the Express5800/A1160 cell. It maintains coherency between the processors, memory, and I

O subsystem and contains extensive error detection and correction logic.

The node controller provides the following interfaces:

•Four dedicated high-speed interconnect interfaces for the processor sockets (one interface for each socket).

•Four fully buffered DIMM interfaces.

•Three x8 PCIe interfaces

•One x4 PCIe interface

•Three high-speed serial interfaces that support 10 high-speed serial lanes in parallel for each direction for each interface. The interface enables a cell to be connected to up to three other cells using interconnect cables that run between the interconnect ports on the rear of the cell.

•Enterprise South Bridge Interface (ESI) to the I/O controller hub (south bridge) Figure 2-3 illustrates the node controller.
