ProLiant 7000 Architecture The ProLiant 7000 architecture allows customers to scale the processor and memory subsystems to run their mission-critical applications. The following sections describe the ProLiant 7000 architecture-the processor board, memory expansion boards, input/output (I/O) board, and standard peripheral board. Processor Board The processor board (Figure 2) has four sockets for Pentium II Xeon processors, four sockets for redundant processor power modules, and two slots for memory expansion boards. The redundant processor power modules maintain the precise voltage requirements of the processors. The memory expansion boards allow customers to scale system memory up to 8 GB. The ProLiant 7000 ships with one Pentium II Xeon processor, one redundant processor power module, and two memory expansion boards. Processor terminator cards are also provided with the server. A processor terminator card must remain in each processor socket not occupied by a processor. Memory Expansion Boards The ProLiant 7000 ships with two memory expansion boards installed on the processor board. As shown in Figure 3, each memory expansion board has sixteen memory sockets (four banks of four sockets) for Dual In-Line Memory Modules, or DIMMs. The DIMMs must be installed in sets of 7
