[HACKERS] Interesting read on SCM upending software and hardware architecture

2016-01-07 Thread Jim Nasby
https://queue.acm.org/detail.cfm?id=2874238 discusses how modern Storage Class Memory (SCM), such as PCIe SSD and NVDIMMs are completely upending every assumption made about storage. To put this in perspective, you can now see storage latency that is practically on-par with things like lock acq
