Optimal BIOS settings for HPC with Dell PowerEdge 12 th generation servers
7
The following features are common to the servers:
 Support for processors from the Intel Xeon E5-2600 series.
 4 memory channels per socket. The number of DIMM slots per server varies by product line.
o 3 DIMMs per channel for the PowerEdge R and M product line. Total of 12 DIMMs per
socket, 24 DIMMs per server.
o 2 DIMMs per channel for the PowerEdge C product. Total of 8 DIMMs per socket, 16
DIMMs per server.
 Support memory speeds of 800 MT/s, 1066 MT/s, 1333 MT/s and 1600 MT/s.
Table 1. Dell PowerEdge 12 th generation server models
Server model Form factor
PowerEdge R620 1U Rack
PowerEdge R720 2U Rack
PowerEdge M620 Half height Blade
PowerEdge C6220 Shared Infrastructure system,
2U Rack with 4 servers.
The servers differ in
 Form factor
 Number of hard drives supported
 Support for hot plug flash storage
 Number of onboard NICs
 Number and configuration of PCI slots
 PERC options for internal and external hard drives
 Support for GP GPU and other PCI cards.
This study used the Dell PowerEdge M620 blade servers, but the recommendations contained here apply
to the PowerEdge R and M server models that use the Intel Xeon E5-2600 series processors.
The PowerEdge C product line has a different BIOS interface from the standard PowerEdge products.
The BIOS layout and the options exposed are different and all 12
th generation features may not apply.
In general, however, the analysis and recommendations in this document will apply to the PowerEdge
C6220 as well.
2.1. Intel SandyBridge architecture
The Intel microarchitecture codenamed Sandy Bridge is the latest “tock” in Intel’s tick-tock model
of development
5 . It uses the same 32nm process technology as its predecessor (Intel Xeon 5600
series, codenamed Westmere-EP) but introduces a whole new microarchitecture.
