Overview and Installation
Getting started with MemVerge Memory Machine requries 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.
  - Installing MemVerge Memory Machine
    Install MemVerge Memory Machine (Memory Machine) data service on all hosts requiring memory management.
    - Installing the Data Service
      Install the data service on every data host using the Memory Machine Package File.
    - Installing the Management Service
      Install the Management Service using the Memory Machine Package File.
    - Initializing Direct Access Devices
      To initialize the server's direct access (DAX) devices and start the Distributed Persistent Memory Engine (DPME) service, use the command mvmallocd <dax device> ... [--socket=<socket>] [--format_dax].
    - Installing a File-Based License using the CLI
      To install or update a file-based license (also called a single-host license), use the mvmcli license update command.
    - 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. See oxy_ex-3/topics/t_mvmm_installing_the_management_service.html. 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.

Installing MemVerge Memory Machine

Install MemVerge Memory Machine (Memory Machine) data service on all hosts requiring memory management.

Installing and preparing Memory Machine for use requires these steps:

On each data host, run the installation script to install the data service. See Installing the Data Service.
The installation script is also used to install the Management Service. You must install the Management Service on one host. See Installing the Management Service. Exception: You can run Standard Edition on individual hosts without installing the Management Service. You must manage these hosts individually, however, and cannot use the Memory Machine Management Center's graphical monitoring capability.
On all data hosts, format DAX devices, start the Distributed Persistent Memory Engine (DPME) service and configure the host to automatically start DPME on bootup. See Initializing Direct Access Devices.
Use the Management Service to install an Advanced Edition or Standard Edition software license (see Uploading a License) – or – install individual licenses on each Standard Edition host (see Installing a File-Based License using the CLI).
Authorize one or more users to the system. See Adding a User.
