NUMA (Non-uniform memory
access)
NUMA node 1
NUMA node 2
Helps hosts scale up the number of
cores and memory access
Partitions cores and memory into
“nodes”
Allocation and latency depends on the
memory location relative to a
processor
Processors

High performance applications
detect NUMA and minimize crossnode memory access

NUMA Node 2 has an odd number of

NUMA Node 3 doesn’t have enough
NUMA Node 4 has no local memory
(worst case)
Host NUMA
Guest NUMA
Presenting NUMA topology within
VM
Guest operating systems & apps
can make intelligent NUMA
decisions about thread and
memory allocation
Guest NUMA nodes are aligned
with host resources
Policy driven per host –
best effort, or force alignment
