26 Release Notes
On a Non-
Uniform Memory
Access (NUMA)
enabled system,
ESX/ESXi may
fail to install or
boot because of
unbalanced
memory
distribution across
the nodes.
On a NUMA enabled
system with unbalanced
memory configuration,
ESX/ESXi may fail to
install or boot. The
following error message
is displayed: The BIOS
reports that NUMA
node X has no
memory. This
problem is either
caused by a bad
BIOS or a very
unbalanced
distribution of
memory modules.
The performance of the
system may be
degraded.
NOTE: The PowerEdge
M905 system installed
with ESX/ESXi and
configured with the Node
Interleaving option as
Disabled (NUMA
enabled) in the system
BIOS may fail to boot.
This issue occurs if the
processor nodes are not
populated with similar
amount of memory.
VMware recommends
populating all the processor
nodes with similar amount
of memory to enable
balanced distribution of
memory across the nodes.
