Designed for HPE ProLiant and Apollo server families, this high-capacity module ensures robust data integrity and enhanced system efficiency, making it ideal for data-intensive workloads, virtualization, and large-scale computing environments. Its low-voltage 1.2V design contributes to reduced power consumption while maintaining superior operational stability.

Characteristics of HPE M0S31A LRDIMM Modules

High-Speed DDR4-2133MHz Memory

The DDR4-2133MHz architecture enables the HPE M0S31A memory module to process data at high transfer rates, providing significant performance improvements compared to older DDR3 modules. The high bandwidth capability supports demanding applications such as large databases, high-performance computing, and virtualized server deployments. Users benefit from reduced latency and faster response times, enhancing overall system productivity.

Quad Rank ECC Registered Configuration

This module utilizes a Quad Rank configuration, providing additional memory ranks per module, which allows servers to handle larger memory footprints efficiently. The ECC (Error Correcting Code) feature ensures that any single-bit errors are automatically detected and corrected, preserving data integrity and minimizing the risk of data corruption during critical operations. ECC Registered technology further stabilizes memory operations, particularly in multi-processor server environments, ensuring reliable performance even under heavy workloads.

Compatibility and Server Integration

HPE Server Compatibility

The HPE M0S31A memory module is fully compatible with a wide range of HPE ProLiant Gen9 and Gen10 servers, as well as select HPE Apollo platforms. Its design follows HPE’s stringent validation standards, ensuring seamless integration with server hardware and firmware. This guarantees that enterprise IT teams can upgrade or expand their memory infrastructure without compatibility concerns, allowing for scalable and efficient server deployments.

Scalability for Enterprise Workloads

With a massive capacity of 128GB per module, these LRDIMMs provide the flexibility required for memory-intensive workloads. Enterprises can scale memory across multiple servers to accommodate large datasets, advanced analytics, and in-memory computing applications. The ability to expand memory without compromising system stability ensures that organizations can meet evolving computational requirements while maintaining high performance.

Power Efficiency and Thermal Management

Low-Voltage 1.2V Design

The HPE M0S31A module operates at an energy-efficient 1.2 volts, reducing overall power consumption compared to standard 1.35V DDR4 modules. This low-voltage design not only lowers operational costs but also contributes to improved thermal performance, helping data centers manage heat generation and cooling requirements more effectively. Lower power draw also extends the lifespan of memory components and other server hardware.

Advanced Thermal Control

Each memory module incorporates advanced thermal sensors and heat spreaders to monitor and manage operating temperatures. These features ensure consistent performance even under high workloads, reducing the risk of thermal throttling or memory-related failures. Reliable thermal management is crucial for enterprise environments, where uptime and stability are paramount.
