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).
Memory Machine Management Service
Memory Machine Management Service (Management Service) runs alongside the Memory Machine data service to handle tasks not having to do with application data.

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).
  - Introduction to PMem
    Using volatile memory (DRAM) and persistent memory (PMem) in combination enables applications to expand memory capacity relatively cheaply and to persist memory data objects, a capability that previously was only possible by writing to storage devices.
  - Transparent Memory Service
    The Transparent Memory Service (TMS) intercepts Linux glibc.so function calls and reroutes them to the MemVerge Memory Allocation Service (MVMAS), which manages the MemVerge PMem store.
  - The MemVerge Memory Allocation Service
    MemVerge MemVerge Memory Allocation Service (MVMAS) is at the heart of Memory Machine. MVMAS manages memory allocation to volatile memory (DRAM) and persistent memory (PMem) for all applications run under Memory Machine.
  - Memory Machine Management Service
    Memory Machine Management Service (Management Service) runs alongside the Memory Machine data service to handle tasks not having to do with application data.
  - Understanding Snapshots
    A snapshot is a static image of a running application's process tree. You can use Memory Machine ZeroIO Snapshot to almost instantly capture a snapshot, then later just as quickly restore the running process to the state captured in the snapshot.
- Getting Started with Memory Machine
  You run Memory Machine on a host equipped with one or more PMem devices.
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.

Memory Machine Management Service

Memory Machine Management Service (Management Service) runs alongside the Memory Machine data service to handle tasks not having to do with application data.

Management Service runs as a service daemon named mmctl. Functions handled by Management Service include:

Running the web server for Memory Machine Management Center
Servicing API requests
Managing and storing configurations
Gathering metrics
Generating logs
Generating a monthly usage report for billing
Communicating with MemVerge if Call Home is active
Managing scheduled jobs such as scheduled snapshots

For the most part these functions do not concern the user, but you should be aware that Management Service exists and needs to be running on Memory Machine. See Running Memory Machine Management Service.

You can install Management Service on a data host in Memory Machine, or on a dedicated host. See Installing MemVerge Memory Machine.
