Reference Configuration 

The hardware platform consists of nodes with dual processors and 384 GB of memory each. The processors are 

Intel

®

 Xeon

®

 processor E5-2680 v3 CPUs, each with 12 cores and operating at 2.5 GHz. The density and number 

of memory DIMMs selected are consistent with Intel’s recommendations for optimal performance given the number 

of memory channels and DIMMs supported by each CPU (Figure 4). 

Figure 4.    Processor Configuration 

 

 

System performance is optimized when the DIMM type and number are the same for each CPU channel. Peak 

memory performance is at 2133 MHz for up to two DIMMs for each CPU. Therefore, a higher-density DIMM is 

recommended to provide the required amount of memory while also delivering peak memory performance by not 

expanding to the third memory channel.  

Hardware and Software Specifications  

Table 2 provides cluster-based specifications. It shows the hardware required for a minimum configuration cluster 

with N+1 resiliency.
