11. • NUMA (Non-uniform memory access) NUMA node 1 NUMA node 2
• Helps hosts scale up the number of
Processors
cores and memory access
• Partitions cores and memory into
Memory
“nodes”
• Allocation and latency depends on the
memory location relative to a processor
• High performance applications detect
NUMA and minimize cross-node
memory access
Host NUMA

12. NUMA node 1 NUMA node 2
• This is optimal… Processors
• System is balanced
Memory
• Memory allocation and thread
allocations within the same NUMA NUMA node 3 NUMA node 4
node
Processors
• Memory populated in each NUMA
node Memory

13. NUMA node 1 NUMA node 2
• This isn’t optimal… Processors
• System is imbalanced
• Memory allocation and thread allocations Memory
across different NUMA nodes
• Multiple node hops
NUMA node 3 NUMA node 4
• NUMA Node 2 has an odd number of
DIMMS Processors
• NUMA Node 3 doesn’t have enough
Memory
• NUMA Node 4 has no local memory (worst
case)
Host NUMA

14. • Guest NUMA
• Presenting NUMA topology within VM
• Guest operating systems & apps can
vNUMA node A vNUMA node B vNUMA node A vNUMA node B
make intelligent NUMA decisions about
thread and memory allocation
• Guest NUMA nodes are aligned
with host resources
NUMA node 1 NUMA node 2 NUMA node 3 NUMA node 4
• Policy driven per host –
best effort, or force alignment
