HPE DDR5 Smart Memory

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 Smart Memory 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 Smart Memory 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.

What is HPE Smart Memory?

HPE Smart Memory uniquely optimizes memory performance on HPE ProLiant Rack and Tower servers, Apollo family servers, Blade systems, and Synergy systems. Authenticated HPE Smart Memory supports extended memory performance in the competitive landscape and provides customers with service enhancement through HPE Active Health Systems and other HPE proprietary software.

Quality and Performance

HPE Smart Memory undergoes a rigorous qualification process to provide customers with the highest server memory quality options. Its performance is tested and optimized for HPE servers, supporting unique features only available with HPE servers and systems. In addition, it enhances memory throughput up to 23% and achieves an improvement in latency of up to 25%.

HPE Active Health System

HPE Smart Memory works in conjunction with the HPE Active Health System which monitors changes to the server hardware configuration to enable lifecycle monitoring of memory health status. Having insight into memory-related service events will shorten problem diagnosis and deliver rapid resolutions if and when failures occur. Whereas the pre-failure alert simply notifies the administrator of an impending failure, HPE Smart Memory can provide rich insight into memory-related events like multi-bit errors or configuration issues.

Reporting Correctable memory errors

Beginning with the HPE Gen10 Plus server generation, the server ROM will provide an option that allows users to control the RAS policies, (including the ability to expose corrected memory errors to the OS and allow it to log them which may make them visible to the user). This new ROM option may be set to either “Firmware First” or “OS First” mode.

Firmware First Mode

When in Firmware First Mode (default), the BIOS will implement RAS features as before, to monitor corrected errors and log an event for any cases where the customer needs to take action on corrected errors. The OS will not monitor and log corrected errors.

Operating System (OS) First Mode

In OS First Mode, corrected errors are unmasked to the OS and the OS will control the policy for logging corrected errors. With some operating systems, while in OS First mode, corrected errors are unmasked to the OS and the OS will control the policy for logging corrected errors. Additionally, the OS may be able to create its own protection from these events by triggering a Page Retire, or other OS level mitigation. When these events happen, they are not deemed to be a trigger for a service action.

With the understanding that corrected memory errors are an expected and natural occurrence and that no action is required based on OS logging of corrected errors (unless the BIOS has also logged an event – which would also occur in the “Firmware First” mode), HPE recommends that this option is left in its default “Firmware First” setting.

However, for customer installations which choose to configure this option for “OS First” mode, no service action should be triggered based solely on the OS logging of corrected memory errors. Service action should only occur if the errors are logged to the Integrated Management Log (IML) by the BIOS.
