Overview and Installation
Getting started with MemVerge Memory Machine requires that you understand some background information about how persistent memory works. You can then install Memory Machine on a server and begin monitoring memory usage and capturing application snapshots.
- Introduction to MemVerge Memory Machine
  MemVerge Memory Machine (Memory Machine) enables applications to expand from volatile memory (DRAM) into persistent memory (PMem).
- Getting Started with Memory Machine
  You run Memory Machine on a host equipped with one or more PMem devices.
  - Hardware Recommendations
  - Network Recommendations
    For optimal performance and consistency throughout the Memory Machine System, MemVerge either requires or recommends specific values for open port numbers, communication protocols, and other network-related configurations.
  - Software Recommendations
    MemVerge recommends that you conform to software dependencies, such as operating systems and packages, that have been tested with MemVerge products.

    - Choosing a Database in Memory Machine Management Center
      Use the Database Settings Console to choose the database used to store your UI configuration, usage data, and other information for the Management Service.
    - Uploading a License
      One host in your network runs the Management Service. Unless you are using only file-based Standard Edition licenses, you must install one license using the Management Service in order to use Memory Machine.
    - Adding a User
      Authorize a user to use Memory Machine by adding the user to the mvmm group.
  - Configuration Files
    MemVerge Memory Machine uses several YAML-formatted configuration files, installed in the /etc/memverge directory. Two of these, mvmallocd.yml and mvmalloc.yml contain user-configurable parameters.
Using the Memory Machine Management Center
Memory Machine Management Center (M3C) is a web UI application available on the host that is running the Memory Machine Management Service. You can view system resources and performance metrics; create and restore snapshots; schedule jobs; and more in M3C.
Using the Command Line Interface
You can administer and use MemVerge Memory Machine using the Command Line Interface (CLI) on any installed host.
Working with Applications
MemVerge provides additional instructions for some popular applications supported by Memory Machine, either to assist with complex setup or to support additional functionality.
