HPE DDR5 SmartMemory

As CPU core counts continue to increase, bandwidth per core cannot continue to scale with DDR4. New memory architectures are required to meet next-generation bandwidth per core requirements in x86 CPUs. With the changing landscape of ever-increasing CPU core counts, DDR5 was designed to increase bandwidth delivered to systems.

DDR5 is the latest evolution in DRAM, delivering a long list of new features designed to increase reliability, availability, and serviceability (RAS); reduce power; and dramatically improve performance - all features that modern data centers require.

Advanced workloads resulting from rapidly expanding datasets and compute-intensive applications have fueled processor core count growth which will be bandwidth-starved by current DDR4 DRAM technology over time. DDR5, the most technologically advanced DRAM to date, will enable the next generation of server workloads by delivering as much as an 85% increase in memory performance. DDR5 doubles memory density while improving reliability at a time when data center system architects seek to supply rapidly growing processor core counts with increased memory bandwidth and capacity.

The need for higher bandwidth and density has been posing a huge challenge for the tech industry, and DDR5 is the new standard that is expected to meet these requirements for years to come.

HPE DDR5 SmartMemory delivers great performance, reliability, and efficiency. Our large selection of server memory solutions provides the compatibility, capacity and bandwidth you need to productively manage your expanding workload with HPE ProLiant Gen11 servers, Apollo family servers, Synergy systems, and Blade systems.

As workloads grow and data center trends such as server virtualization, cloud computing, and the use of large database applications increase the need for higher-capacity memory with greater uptime, the quality and reliability of DRAM become ever more important. HPE SmartMemory goes through additional rigorous qualification and testing processes that unlock extended memory performance features available only with HPE Gen11 servers. This extensive testing ensures that HPE server memory is completely compatible with and optimized for HPE servers.
