Persistent memory (PMEM) is a new technology that bridges the gap between DRAM and traditional storage.
It has the speed characteristics of memory, but it retains data through power cycles. While maintaining persistence of data across reboots and crashes, when compared to traditional storage, PMEM offers performance advantages such as DRAM-like latency and bandwidth, and use of regular load/store byte-addressable instructions.
These characteristics make PMEM very attractive for a varied set of applications and scenarios. This paper looks at Intel Optane DC persistent memory performance in vSphere 6.7.
