Option Description
NOTE: The Memory Operating Mode option can have dierent default and available options based on
the memory conguration 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
Species the current state of the memory operating mode.
Node Interleaving Species if Non-Uniform Memory Architecture (NUMA) is supported. If this eld is set to Enabled, memory
interleaving is supported if a symmetric memory conguration is installed. If the eld is set to Disabled, the system
supports NUMA (asymmetric) memory congurations. This option is set to Disabled by default.
Opportunistic Self-
Refresh
Enables or disables opportunistic self-refresh feature. This option is set to Disabled by default.
Persistent Memory This eld controls Persistent Memory on the system.
Persistent Memory details
The Persistent Memory screen details are explained as follows:
Option
Description
Persistent Memory Enables or disables persistency for NVDIMM-N. If this option is set to O, persistency for all NVDIMM-N 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 and
Secure Erase 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 aected 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-Oine
• Not-Ready
The following settings are applicable for every NVDIMM-N present in the system.
NVDIMM-N
Memory Location
Species the location of the NVDIMM-N in each channel.
NVDIMM-N
Memory Size
Species information on the capacity of the NVDIMM-N.
NVDIMM-N
Memory Speed
Species information on the speed of the NVDIMM-N.
NVDIMM-N
Memory Firmware
version
Species information on the current rmware version on the NVDIMM-N.
