It was an outstanding conference and I was able to learn a lot on what some options for persistent memory configurations will be in 2019 and beyond. Spoiler Alert: Optane DIMMS are involved in both cheapest and most expensive options
I converted it to customer cost for Storage/Memory components in the system for some typical options including a medium SSD and big HDD
If you disagree, please tell me the correct answer (hint: Facebook, Intel, Dreamworks... my email is below).
I have specifics on why these options are probable, what the actual speeds are, and the costs for each components. Contact us for more info and system requirements estimates
Background Assumptions
- DRAM is fastest, Optane is somewhat slower but good enough. DRAM acts as cache for Optane DIMMS (Optane requires DRAM, it doesn't replace DRAM)
- NVDIMM-N is DRAM speed... and DRAM density ... and more expensive than DRAM. But Persistent!
- You still need to store stuff and HDD is about 50x cheaper than Optane, 10x cheaper than SSD
The Hypothetical Costs to a end user for some typical options
- If you want TONS of addressable memory, Optane DIMMS might be the answer
- If you want speed and persistence, NVDIMM-N might be the answer
- If you want max speed and not persistence DRAM only might be the answer
- If you are cheap: 64GB of DRAM plus an off brand SSD from Craigslist will do the trick
Just an opinion!

Mark, thanks for your time in attending the SNIA Persistent Memory Summit, and for this informative article.
