Features Summary

Single Technology Configured as Large Server Memory or Fast Storage Data Center Complexity
Intel Optane persistent memory for HPE can move, store, and process larger data sets closer to the processor.
App Direct Mode – both byte and block addressing supported.
DIMM form factor installed in a server memory slot.
Up to 1.6x more virtual machines while in memory mode.
Up to 3x more performance than NVMe SSDs.
Cost-effective Dense Memory for Larger Compute Needs
Intel Optane persistent memory for HPE is more affordable than the equivalent DRAM.
Offers higher capacity than what is achievable with DRAM alone.
Up to 2x the capacity of DDR4 server memory.
Available in 3 different capacities –128 GB, 256 GB, 512 GB.
Configurations with lower $/GB than DRAM-only configs.
Transform Critical Data Centric Workloads
Intel Optane persistent memory for HPE boosts the performance of data-intensive applications.
Enables more compute capability for memory-intensive applications.
Delivers more server instances, improves service scalability and ownership costs for virtualization workloads.
Take Advantage of HPE Reliability Features in both Memory Mode and App Direct Mode
HPE provides an advanced error correcting code (ECC) feature, making it possible to correct memory errors that might go uncorrected and cause unplanned downtime.
Advanced ECC memory is the default memory protection mode for HPE servers.
Smart Data Integrity Check during boot in App Direct Mode.
Increased patrol scrub interval, especially for Memory Mode.
More aggressive HPE SmartMemory recovery algorithm.
