[VB] Optane persistent memory: Is the end of conventional client storage almost here?

Source: https://venturebeat.com/2020/02/03/o...e-almost-here/

We recently discussed the prospect of Intel Optane DC persistent memory (DCPMM) migrating from the data center to workstation systems. The upshot: The benefits that Optane DCPMMs bring to servers also advantage workstations. Both system types need more speed than even SSDs can provide to handle increasingly massive workloads from ever-larger databases and file sets.

At last fall’s Intel Memory and Storage Day 2019 in Seoul, company executives outlined their anticipated future for Optane. Most presentations focused on the data center, where Optane DC Persistent Memory (DCPMM) and Optane DC SSDs have enjoyed growing success over the past two years — as well as on Optane’s roadmap into 2020’s second-generation (“Barlow Pass”) Optane media and beyond. As we noted previously, Intel looks set to begin pushing Optane persistent memory modules (PMMs) into workstations. The slide below from the event shows the nod Intel gave to client PMMs, made more concrete with support from Microsoft.

Because Optane persistent memory can act as non-volatile storage while running alongside DRAM on the memory bus, it makes possible a system with zero PCI Express-or SATA/SAS-based storage. To prove the point, Intel showed off a tower system, complete with a GeForce GTX 1080 and wall-to-wall fans, with two 16GB DDR4 modules accompanying a single 512GB Optane DCPMM, all running Windows 10 for Workstations. The specialized box didn’t reveal what exact Xeon (3.31 GHz) it sported, but the benchmarks displayed for the Optane system (compared to the same config relying on NVMe SSD storage) were impressive. Content creation and video rendering scores showed results 3x to 4x greater for Optane.

Hopefully optane dimms don't need to occupy threads to load game resources in app direct mode: https://thessdguy.com/intels-optane-...p-direct-mode/

Save a lot of power using just the memory controller instead of a bunch of cores in addition to that.

That's really not any different than the same quantity of ddr4 though. I'd say that's some pretty exceptional pricing for a paradigm-shifting product.

by that price trend, i'd expect 64GB stickswould cost $200, a fair bit cheaper than DDR4 64GB kits.

on this note, this can open up some very flexible configurations as it supports DIMM mixing with DDR4.
so you can get a high-speed 2x8GB 4000MT/s DDR4 kit and pair it with a 64GB DCPMM for much lower cost than buying a 64GB 4000MT/s DDR4 kit.

maybe one of these days we'd find a DRAM-DCPMM hybrid sticks that has both speed and capacity at a much lower cost.

trolling an adult is very dangerous, don't try it at home nor at work. you don't want to play tag with a rabid man.

I was reading a long white paper on optane memory in which another suggested use for optane memory was to increase the amount of system RAM because optane has greater capacity than memory DIMM's. I believe this same white paper suggested using the actual DRAM as a kind of cache for the optane memory.

Been interested in similar technology since the Cenotek Rocket RAM 20 years ago.
My beef is I need 8GB to house the OS and buffers to stream audio.
Sure would be noticeably quicker but I could do everything I needed with DDR3 1600.

I’d rather but a new car for cash with no payments and my own insurance...

Does Optane really have any value for non-content creation and are the benefits only seen in content creation if all the assets are saved onto the optane memory? Like say you are creating a render on blender, windows and blender are installed onto the optane drive, but all the texture assets are saved onto an SSD?

This is cheaper than I would have expected for the 128gb module. Maybe I'm getting used to seeing extreme pricing on the bleeding edge though.

It's got some nice advantages but for the average person traditional SSD based storage still looks like the best choice.

Quis custodiet ipsos custodes?

I've been wondering the same thing. All this time and I've had it disabled.
