Intel’s new Persistent Memory called Intel Optane DC Persistent Memory, is a new type of computer storage, combining speeds approaching those of dynamic RAM (DRAM) along with RAM’s byte-by-byte address-ability, plus the permanence of solid-state disks (SSDs). Intel’s Persistent Memory Approach – Overview This blog is focused on providing an overview on each persistent memory technology and how HANA as a database enables the use of Persistent Memory. So I thought of writing this blog to provide more insight on both – Intel and IBM’s persistent memory technology and pen down the steps on how to configure persistent memory on IBM POWER9 Server. Recently, I have worked on configuring IBM’s Virtual Persistent Memory (vPMEM) on POWER9 System for SAP HANA. So now we have two technology with which we can adopt HANA to enable the use of Persistent Memory. Later after that, IBM introduced Virtual Persistent Memory (vPMEM) in the virtualization platform of IBM Power Systems. Ever since then, I regularly followed the announcement of this persistent memory technology and on 2nd April, 2019 Intel announced the general availability of Intel Optane DC Persistent Memory (link of my previous blog). In late 2018, when I first read this whitepaper on SAP HANA Adoption of Non-Volatile Memory it kept me hooked on Persistent Memory technology and its usage with HANA.
