NOTE:
The Memory Operating Mode can have different defaults and available options based on the
memory configuration of your system.
NOTE:
The Dell Fault Resilient Mode establishes an area of memory that is fault resilient. This mode
can be used by an operating system that supports the feature to load critical applications or enables the
operating system kernel to maximize system availability.
Current State of
Memory Operating
Mode
Specifies current state of memory operating mode. Option is
Optimizer
.
Node Interleaving
Specifies if Non-Uniform Memory architecture (NUMA) is supported. If this field is
Enabled
, memory interleaving is
supported if a symmetric memory configuration is installed. If
Disabled
, the system supports NUMA (asymmetric)
memory configurations. By default,
Node Interleaving
option is set to
Disabled
.
