ISS Technology Update Volume 8, Number 4 Optimizing memory performance in ProLiant G6 Intel-based servers To achieve higher performance and better efficiency, the new HP ProLiant G6 servers featuring the Intel® Nehalem architecture use a memory architecture that is significantly different than previous generations of servers.

ISS Technology Update Volume 8, Number 4 Figure 1-2. Intel Nehalem architecture with NUMA Understanding and optimizing memory performance in G6 servers With Intel Nehalem architecture, each processor has its own memory controller and three memory channels that it controls directly. In its fastest configuration, the new DDR3 memory used with these systems operates at 1333 Megatransfers per second.

ISS Technology Update Volume 8, Number 4 Unbuffered DDR-3 DIMMs are a cost-effective solution for ProLiant G6 servers HP ProLiant G6 servers support Double Data Rate-3 (DDR-3) Synchronous Dynamic Random Access Memory (SDRAM) technology. DDR-3 SDRAM technology doubles the peak bandwidth of DDR-2 when operating at the same memory bus frequency. Memory manufacturers are producing two types of DDR-3 SDRAM DIMMs: Registered DIMMs (RDIMMs) and Unbuffered DIMMs (UDIMMs).

ISS Technology Update Volume 8, Number 4 The transition from Megahertz to Gigatransfers Traditional front side bus architecture The front side bus (FSB) has been the traditional interconnect between processors and the system chipset. The FSB is unidirectional and it is shared by all of the devices (processors and chipset) that are attached to it. The FSB in Intel processorbased systems is clocked at a frequency (speed) of 266 MHz, 333 MHz or 400 MHz.
