Option DescriptionNOTE: The Memory Operating Mode option can have different default and available options based onthe memory configuration of your system.NOTE: The Dell Fault Resilient Mode option establishes an area of memory that is fault resilient. Thismode can be used by an operating system that supports the feature to load critical applications orenables the operating system kernel to maximize system availability.Current State ofMemory OperatingModeSpecifies 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, memoryinterleaving is supported if a symmetric memory configuration is installed. If the field is set to Disabled, the systemsupports NUMA (asymmetric) memory configurations. This option is set to Disabled by default.Opportunistic Self-RefreshEnables or disables opportunistic self-refresh feature. This option is set to Disabled by default.Persistent Memory This field controls Persistent Memory on the system.Persistent Memory detailsThe Persistent Memory screen details are explained as follows:Option DescriptionPersistent Memory Enables or disables persistency for NVDIMM-N. If this option is set to Off, persistency for all NVDIMM-N isdisabled and is not presented to OS (data is not preserved). If this option is set to Non-Volatile DIMM, persistencyfor all NVDIMM-N is enabled and presented to OS (data is preserved). This option is set to Non-Volatile DIMM bydefault.NVDIMM-N Read-OnlyEnables 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 dataand also to lock it from being updated. This option is set to Disable by default.NVDIMM-NFactory Reset andSecure Erase AllDimmsEnables or disables clearing data on the NVDIMM-N. If set to Enable, all data on the NVDIMM-N is lost. Thisoption is used to remove data on the NVDIMM-N, repurpose your system. This option is set to Disable by default.NVDIMM-NInterleaveEnables 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• Not-ReadyThe following settings are applicable for every NVDIMM-N present in the system.NVDIMM-NMemory LocationSpecifies the location of the NVDIMM-N in each channel.NVDIMM-NMemory SizeSpecifies information on the capacity of the NVDIMM-N.NVDIMM-NMemory SpeedSpecifies information on the speed of the NVDIMM-N.NVDIMM-NMemory FirmwareversionSpecifies information on the current firmware version on the NVDIMM-N.Dell EMC PowerEdge R740 Installation and Service ManualPre-operating system management applications45
