Glossary
Term
Definition
3D XPoint
3D Xpoint is a non-volatile memory (NVM) technology developed jointly by Intel and
Micron Technology.
ACPI
The Advanced Configuration and Power Interface is used by BIOS to expose platform
capabilities.
ADR
Asynchronous DRAM Refresh is a feature supported on Intel that triggers a flush of
write pending queues in the memory controller on power failure. Note that ADR does
not flush the processor cache.
AMD
Advanced Micro Devices https://www.amd.com
BIOS
Basic Input/Output System refers to the firmware used to initialize a server.
CPU
Central processing unit
DCPM
Intel Optane DC persistent memory
DCPMM
Intel Optane DC persistent memory module(s)
DDR
Double Data Rate is an advanced version of SDRAM, a type of computer memory.
DDIO
Direct Data IO. Intel DDIO makes the processor cache the primary destination and
source of I/O data rather than main memory. By avoiding system memory, Intel DDIO
reduces latency, increases system I/O bandwidth, and reduces power consumption
due to memory reads and writes.
DRAM
Dynamic random-access memory
eADR
Enhanced Asynchronous DRAM Refresh, a superset of ADR that also flushes the CPU
caches on power failure.
