Linux 5.1 Might Pick Up Support For Using Persistent Memory As System RAM

While we are expecting to see more Intel Optane NVDIMMs this year that offer up persistent memory using 3DXPoint memory on the DDR4 bus for persistent storage, the Linux 5.1 kernel might pick-up support for treating this persistent memory back as traditional RAM if so desired.

Intel Optane DC Persistent Memory is expected to begin appearing in more servers this year for offering application-level persistent memory for use-cases like database servers, HPC, and other enterprise computing possibilities. If you are buying such NVDIMMs in the first place, chances are you planning to utilize the persistent memory for such purposes, but otherwise with Linux 5.1 there are patches pending to allow this PMEM to function as traditional system RAM.

Linux 5.1 Might Add Support For Using Persistent Memory

Submitted by Roy Schestowitz on Tuesday 12th of March 2019 10:58:54 AM.
  • Linux 5.1 Might Add Support For Using Persistant Memory As System RAM

    There are numerous differences when it comes to traditional RAM and flash storage. While both might be using solid state technologies, RAM is known to be much faster, costly, and speedy. With new solutions like Intel Optane DC Persistent Memory, things are going looking a bit different as it continues to bridge the gaps between non-volatile storage and RAM.

    As the adoption of Optane memory is picking up the pace, it makes sense for Linux kernel to introduce the support for using the persistent memory as a traditional RAM.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
