on the memory configuration of your system.
NOTE: The Dell Fault Resilient Mode option 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 the current state of the memory operating mode.
Node Interleaving Specifies if Non-Uniform Memory Architecture (NUMA) is supported. If this field is set to Enabled,
memory interleaving is supported if a symmetric memory configuration is installed. If the field is set
to Disabled, the system supports NUMA (asymmetric) memory configurations. This option is set to
Disabled by default.

is disabled and is not presented to OS (data is not preserved). If this option is set to Non-Volatile
DIMM, persistency for all NVDIMM-N is enabled and presented to OS (data is preserved). This option is
set to Non-Volatile DIMM by default.
NVDIMM-N
Read-Only
Enables or disables the read-only option for the NVDIMM-N. If set to Enable, all NVDIMM-N is forced to
read-only. Read-only is intended to be for debug or maintenance when customers would like to access the
NVDIMM-N data and also to lock it from being updated. This option is set to Disable by default.
NVDIMM-N
Factory Reset

All Dimms
Enables or disables clearing data on the NVDIMM-N. If set to Enable, all data on the NVDIMM-N is
lost. This option is used to remove data on the NVDIMM-N, repurpose your system. This option is set to
Disable by default.
NVDIMM-N
Interleave
Enables or disables interleaving on NVDIMM-N. Volatile RDIMM interleaving policy is not affected by this
option. This option is set to Disable by default.
Battery Status Indicates if the NVDIMM-N battery is ready. Battery Status can display one of the following states:
● Present-Ready
● Present-Offline
