Comment Re:But 32 bits is enough for anybody (Score 1) 164 164

ARIN already laid out several phases. A few months ago they started to limit how many IPs they handed out, a month ago they started to reject some requests. We're reaching the end game, which includes reclaiming IPs. You will need to prove every year that you still need your blocks more than others, and every year ARIN will get more strict and refuse renewal for some customers so other customers that are more deserving get some. It will start to get painful.

Some CDNs are seeing 18%-40% of web requests from AT&T, Verizon, or Comcast are over IPv6. IPv6 is still growing at an exponential rate for almost a decade now, about 100% per year. At the current about 10% of all USA, given 100% growth that hasn't shown any signs of stopping, we'll be at 40% in two years and 80% in 3 years.

Memristor is an a pseudo-object with a set of meta properties. A lot of things could be technically be a memristor. Human skin can technically be one, but making use of it would be rather difficult. XPoint may be similar to a memristor in a layman's sense, but Intel may realize that XPoint only has the property of storage, which is not the only meta property required. It is also not phase-change because nothing physical changes. Not much information to go on.

The only thing for sure is it is a form of ReRAM.

Intel said they're unifying memory and storage with this. No more distinction between DRAM and HDs, they're one and the same. Of course other stuff needs to happen first, but that obviously indicates that they expect it to replace DRAM. Actually, the explicitly stated they will make DRAM with it.

Unofficial sources are starting to say that XPoint does not exhibit wear from write cycles and the "1000x more endurance" is normalized to some other metric. If it was normalized against time, then you may expect NAND to last 3-5 years which would put XPoint around 3,000-5,000 years life time. We won't know until more official data or hands-on reviews happen.

DDR3 is about 10ns. If XPoint is 1000x faster than 5us NAND, then it has 1/2 the latency of DRAM. I doubt it, but you can see how it can easily be within a a factor or two.

When you restart your computer without a power down, you still have all that data in memory. Same difference. As for a power down, the only real benefit is it also resets the CPU and other hardware. When the BIOS starts up and copies data from the HD into memory, it already over-writes what was ever there. No changes required. If you want to take advantage of having persistent memory, then you'll need new protocols, but old protocols should continue to work as expected.
