I'm lurkin' too. Reconfiguring my server cluster for high availability. Some pretty killer backend upgrades. Pretty sweet, all coming together nicely. You may be able to notice when the site has migrated to the new setup. Some really heavy database queries in testing are returning at least twice as fast as they currently do. In the latest configuration I'm running directly off 100% Optane memory. I swear, it's alien technology. It's not about how fast it is, there's faster (on paper, if only scratching the surface -- totally different story in the real-world) -- but it's at what queue depth that matters. And there are NAND drives out there that perform amazing. But what none of them have compared to Optane... Optane can write directly to memory without the need for DRAM cache, it's THAT fast Optane doesn't need to first erase the cell before writing Optane has nearly unlimited write endurance Optane loses no performance as the drive fills up Optane does not require trim (goes on and on really) -- it's in between RAM and NAND For my workload it feels the same as going from HDD to solid state. Or from solid state to raid-10 solid state. It's that big of a difference, mind blowing really. Over just a few days of testing I thrashed it with about 60 TB of data and it never broke a sweat -- literally, the drive didn't fluctuate in temp.

Do you realize who I am? HIT ME! I DARE YOU! This is my idle temp FOO!" -- in other words, it's bad ass. It's a different kind of memory entirely.
