Intel Optane persistent memory 200 series for HPEIntel Optane persistent memory 200 series for HPE
Intel Optane persistent memory 200 series for HPE offers the flexibility to deploy memory as dense memory (Memory mode) or fast
storage (App Direct mode) and enables per-socket memory capacity of up to 4.0 TB. Persistent memory modules, together with
traditional volatile DRAM DIMMs, provide fast, high-capacity, cost-effective memory and storage to transform big data workloads and
analytics by enabling data to be stored, moved, and processed quickly.
Persistent memory modules use the standard DIMM form factor and are installed alongside DIMMs in a server memory slot. Intel Optane
persistent memory 200 series for HPE is designed for use only with third-generation Intel Xeon Scalable processors, and is available in
the following capacities:
128 GB
256 GB
512 GB

Persistent memory modesPersistent memory modes
Intel Optane persistent memory 200 series for HPE can be configured to operate in two modes.
App Direct modeApp Direct mode
When configured for App Direct mode, persistent memory modules function as persistent memory.
Memory modeMemory mode
When configured for Memory mode, persistent memory modules function as volatile system memory while DRAM capacity operates as a
cache. For more information, see Memory cache ratios.
Persistent memory modes 9
Memory cache ratiosMemory cache ratios
Persistent memory modules can be carved into volatile and persistent regions.
For the volatile region, the ratio of volatile memory capacity to DRAM capacity affects performance. The recommended volatile memory
capacity to DRAM capacity is between 4:1 and 16:1:
4:1—largest cache; most likely to get cache hits.
8:1
16:1—smallest cache; least likely to get cache hits.
Users are strongly recommended not to configure for Memory Mode when the ratio is at 1:1 or lower due to more severe performance
impact.
A message will be logged to the Integrated Management Log (IML) if a cache ratio that is not recommended is used.
The following table contains example configurations, with 100% of the persistent memory module capacity allocated to volatile memory.
Cache ratios improve as some of that memory is carved into persistent memory.
