HPE 128GB (1x128GB) Octal Rank x4 DDR4-2666 CAS-19-19-19 Load Reduced Smart Memory Kit

The HPE 128GB (1x128GB) Octal Rank x4 DDR4-2666 CAS-19-19-19 Load Reduced Smart Memory Kit (838087-B21) is a high-capacity LRDIMM module engineered for HPE ProLiant Gen10 servers. Operating at DDR4-2666 with a CAS latency of 19-19-19, the module leverages Load Reduced DIMM architecture to place a data buffer between the DRAM and the memory controller, significantly reducing electrical load and enabling the high rank density required for maximum per-socket memory population. The x4 DRAM width per rank, combined with octal-rank organization across a single 288-pin DIMM, allows this module to deliver 128GB of addressable capacity from a single slot without sacrificing signal integrity at DDR4-2666 transfer rates.

As an HPE Smart Memory component, the module contains an embedded Serial Presence Detect (SPD) mechanism that communicates directly with HPE's Advanced Memory Protection and management firmware. This enables features such as online spare memory, mirrored memory configurations, and memory lock-step support when deployed on compatible HPE ProLiant platforms. The module is manufactured to HPE's component qualification standards, ensuring interoperability validation with HPE server platforms, BIOS, and iLO management infrastructure — reducing integration risk in mission-critical environments.

This LRDIMM is purpose-built for workloads requiring the largest possible in-memory datasets within a given server footprint. Hyperscale virtualization hosts, in-memory databases, large-scale data analytics engines, and AI/ML inference nodes all benefit from the module's ability to expand usable system memory to multi-terabyte configurations when fully populating a multi-socket HPE Gen10 server. Its DDR4-2666 operating frequency balances raw bandwidth with the stability demanded by 24/7 datacenter and cloud infrastructure operations.

Ideal for

• High-density VMware vSphere or Microsoft Hyper-V virtualization hosts requiring maximum vRAM per physical server to increase virtual machine consolidation ratios
• SAP HANA and Oracle Database In-Memory deployments where multi-terabyte in-memory dataset capacity is achieved by fully populating HPE ProLiant Gen10 two-socket servers
• AI and machine learning inference servers that stage large model weights and feature datasets entirely in DRAM to minimize latency between inference requests
• Large-scale Hadoop, Spark, or similar distributed analytics clusters where per-node memory capacity directly affects shuffle performance and intermediate data spill reduction
• Enterprise ERP and CRM platforms running on HPE ProLiant Gen10 infrastructure that demand high memory capacity for concurrent user session handling and caching layers
• High-performance computing (HPC) nodes requiring maximum addressable memory per socket to support large simulation datasets and complex computational fluid dynamics or finite element analysis workloads
