Conclusions
When planning an x64 HP SBC environment, you should select servers equipped with multi-core
processors to help maximize scalability. If your budget allows, consider the fastest processors, the
most cores, and largest cache; if your objective is to reduce overall power consumption and you are
prepared to accept a small performance penalty, use low-power processors.
Memory is an important factor in the x64 environment: while an x64 platform can utilize more RAM,
it also has a higher minimum RAM requirement than an x86 platform. Since a system that is not
memory-starved is less likely to experience disk I/O bottlenecks, HP recommends adding as much
RAM as your budget permits.
For optimal performance, configure FBWC for 100% write. Consider using 15,000 rpm SAS drives.
Virtualized server
Do not oversubscribe vCPUs – after a certain point, additional vCPUs can degrade performance.
Determine the optimal server configuration for your particular workload: How many VMs? How many
vCPUs? How much memory? Significant testing may be required.
Consider virtualizing later x86 platforms to take advantage of improvements made to processors,
memory, and I/O. You may experience dramatic scalability enhancements.
