DDR3 and AMD 2P/4P systems architecture
AMD-based HP ProLiant servers have used NUMA architecture since their inception. The ProLiant G7
servers are the first generation to use DDR3 memory. Figure 7 shows processor/memory architecture
for an AMD-based 4P ProLiant G7 server with three DIMM sockets per memory channel.
