#2I thought I could throw away my DRAM and SSD, but it looks like for now it's just another cache level.

#3Quite a bit of marketing-speak here on the official site, without a lot of technical details.
I know the Optane SSD drives are fast -- is this just device-side driver software that allows you to virtually expand available "RAM" and mmap it to the SSD?
Why just i7 CPUs? Is there a hardware component?
"Just download and install the driver..." (Linux?)

Seems like its some i3/i5/i7, only recent ones? Must be some hardware component to it that makes the SSD look like memory to the system, perhaps as another NUMA zone (could you have a huge NUMA zone with no CPU attached?)

#5It looks to be an accelerator cache for HDDs, but slower than an SSD, with fairly low capacity. And it requires a 7th gen intel processor, so this isn't a performance boost for older PCs either. Exactly who is this aimed at?

I think it will be a bit different once they start selling DIMMs. I'm looking forward to seeing how that works out.

What I understand of it, after skipping through all the marketing speak, is that the Optane Memory functions a cache for your SATA drive. The Optane cache is just a Optane SSD which uses some new and apparently faster 3D Nand technology.
And about Linux; somewhere in the PDF with the technical details it states the requirement that your OS has to be 64 bit Windows ..

At least Lenovo was supposed to offer these as option for some of their laptops.
Maybe this makes sense if you need lots of space. Over 1TB SSDs are expensive.

Data centers willing to provide dense storage instances?

#10Isn't this just another go at Robson and SRT?
