HPE 879505-B21 32GB DDR4 ECC RDIMM SmartMemory
Overview
The HPE 879505-B21 is a 32GB DDR4 Registered ECC SmartMemory module designed for HPE ProLiant Gen10 server platforms. It is used in enterprise environments that require high-capacity memory for virtualization, in-memory databases, and large-scale application workloads.
The module operates at 2666 MT/s (PC4-2666) and uses dual-rank architecture with ECC support to ensure data integrity and stable performance under continuous server workloads. Registered DIMM design enables higher memory density per system while maintaining signal stability in multi-module configurations.
It is commonly deployed in ProLiant rack and tower servers where scalable memory capacity is required for consolidated workloads, virtualization clusters, and high-performance computing environments. The module supports balanced performance and reliability in enterprise-grade infrastructures.
The memory integrates with HPE SmartMemory technology, enabling platform validation, optimized system performance, and enhanced reliability reporting within supported HPE ProLiant ecosystems.
Typical Deployment Scenarios
- Virtualization cluster memory expansion
- Enterprise database in-memory workloads
- Cloud infrastructure compute nodes
- High-density application hosting servers
- HPE ProLiant Gen10 server upgrades
- Consolidated enterprise workloads
