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
- 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!
