HPE 835807-B21 256GB Intel Optane DC Persistent Memory 2666MHz

HPE 835807-B21 256GB Intel Optane DC Persistent Memory

The HPE 835807-B21 is a 256GB Intel Optane DC Persistent Memory module engineered for enterprise-grade HPE ProLiant Gen10 servers. This solution introduces a new memory tier that bridges the gap between traditional DDR4 DRAM and storage, delivering large memory capacity with data persistence to support demanding, data-intensive workloads.

Designed for modern data centers, HPE 835807-B21 enables faster system recovery, reduced downtime, and improved application responsiveness. Unlike conventional memory, this persistent memory module retains data after power loss, allowing systems to restart quickly without reloading large datasets from storage.

Persistent Memory Technology Overview

The HPE 835807-B21 Persistent Memory Kit is based on Intel Optane DC Persistent Memory technology, which uses 3D XPoint architecture to deliver a unique combination of low latency, high endurance, and large capacity. This technology allows frequently accessed data to reside closer to the CPU, improving performance for memory-bound applications.
