HPE 815101-B21 64GB DDR4 ECC LRDIMM SmartMemory
Overview
The HPE 815101-B21 is a 64GB DDR4 Load Reduced ECC (LRDIMM) SmartMemory module designed for HPE ProLiant Gen10 server platforms. It is used in enterprise environments that require high memory capacity per server for virtualization, large databases, and memory-intensive workloads.
The module operates at 2666 MT/s (PC4-2666V) and uses LRDIMM architecture to reduce electrical load on the memory controller, allowing higher total memory population per system compared to standard RDIMM modules. This makes it suitable for dense, high-capacity server configurations.
It is typically deployed in ProLiant rack servers and blade systems where maximizing memory scalability is critical for consolidation, cloud infrastructure, and enterprise application hosting. The quad-rank 4Rx4 design supports stable operation in heavily populated memory channels.
The module integrates with HPE SmartMemory validation, ensuring platform compatibility, optimized performance behavior, and improved reliability reporting within supported HPE ProLiant Gen10 ecosystems.
Typical Deployment Scenarios
- Virtualization cluster memory expansion
- Large-scale database workloads
- Cloud and hybrid infrastructure nodes
- High-density enterprise application hosting
- HPE ProLiant Gen10 server upgrades
- Memory-intensive analytics environments
