Guest Numa - Hitachi Compute Blade 500 Series User Manual

Guest NUMA

Overview
NUMA (Non-Uniform Memory Access) is an architecture where memory is
shared in a multiprocessor computer system. To create an LPAR that meets
all of the conditions listed below, we recommend that you use a NUMA
configuration so you can easily improve memory access and memory
bandwidth. The NUMA running on an LPAR is called a guest NUMA.
• You are creating an LPAR on a server blade in an SMP configuration.
• You are creating an LPAR with the processor scheduling mode set to
dedicated mode.
• You are manually specifying the number for the physical processor to be
assigned to the LPAR and making the number fixed.
