By combining DDR4 SDRAM with Intel Optane DC Persistent Memory technology, this module provides the high-speed access of conventional DRAM while offering persistent memory functionality to retain data during system power cycles, ensuring data reliability and accelerated workload performance.

Intel Optane DC Persistent Memory Architecture

Intel Optane DC Persistent Memory is built to provide data persistence while delivering near-DRAM performance. The Intel NMA1XBD128GQS leverages this architecture to maintain critical data in memory across power cycles, reducing the overhead of data reload from storage during system restarts. This persistent functionality is highly advantageous for applications such as in-memory databases, real-time analytics, and AI/ML model training, where repeated access to large datasets is required. The memory module can operate in two main modes: App Direct mode and Memory Mode. App Direct mode allows applications to directly utilize persistent memory, maintaining data integrity with high-speed access, whereas Memory Mode uses the persistent memory as an extension of DRAM, increasing overall memory capacity while applications remain unaware of the underlying persistent memory technology.

High-Capacity 128GB Modules for Scalable Enterprise Servers

With 128GB per module, the Intel NMA1XBD128GQS allows enterprises to achieve high-density memory configurations without occupying numerous DIMM slots, which simplifies server design and improves thermal management. High-capacity memory modules are critical in virtualized environments where multiple virtual machines require substantial memory allocations to function efficiently. By deploying 128GB Optane DC Persistent Memory modules, data centers can reduce the total number of DIMMs needed to achieve a large memory pool, ensuring more efficient airflow, easier maintenance, and reduced power consumption per server.
