The following table describes each option that is available in the BIOS setup screen.
Table 7. BIOS setup screen
Option Description
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. Node Interleaving is not supported when NVDIMM-N
is present in the system.
WARNING: When Persistent Memory Interleaving is enabled in the Persistent
Memory System Setup page, Node Interleaving setting also applies to Persistent
Memory Interleaving.
This option is set to Disabled by default.
Persistent Memory Enables or disables NVDIMM-N operation. If this option is set to Off, NVDIMM-Ns are not
mapped to System Physical Address (SPA) and are not presented to the OS. Data that has
already persisted to NVDIMM flash are unaffected and are available for OS utilization when this
option is returned to Non-Volatile DIMM.
This option is set to Non-Volatile DIMM by default.
NVDIMM-N Read-Only When set to Enable, this forces NVDIMMs to be read-only. NVDIMM-N data is accessible to
the OS but locked from any modifications. Read-only is intended for debug or maintenance
operations.
This option is set to Disable by default.
NVDIMM-N
Factory Reset and
Secure Erase All
Enables resetting the NVDIMM-N to factory defaults and clearing data on the NVDIMM-N. If set
to Enable, all data on all NVDIMM-N will be erased. This option does not clear the NVDIMM’s
health information, and should be used to remove data and/or repurpose the NVDIMM-N. The
reset and data erasure will occur when BIOS confirms that Setting Changes should be saved.
