The correct answer is B. Benchmarks on x86 systems exclude VMware overhead but the POWER Hypervisor is always. See the full explanation below for the reasoning.

Question

A prospective client is planning a server consolidation project which relies heavily on virtualization technologies. The client showed some SPEC benchmark numbers that made POWER7 and Xeon performance appear to be equivalent. Which response articulates the advantage of Power Systems when used in benchmarks?

Options

  • ABenchmarks do not utilize SMT and will show less positive results than can actually be obtained.
  • BBenchmarks on x86 systems exclude VMware overhead but the POWER Hypervisor is always
  • CBenchmarks for POWER7 do not recognize that execution speeds will increase as performance
  • DBenchmarks run on x86 architecture servers use different rules and generally show better results
