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.

MemVerge Memory Machine (Memory Machine) enables applications to expand from volatile memory (DRAM) into persistent memory (PMem).

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.

Introduction to MemVerge Memory Machine

MemVerge Memory Machine (Memory Machine) enables applications to expand from volatile memory (DRAM) into persistent memory (PMem).

Memory Machine enables networked systems to take advantage of PMem, increasing performance and making systems more robust – for example, by making system recovery easier. Memory Machine functionality includes:

A memory management service and a dynamically loadable library that together enable applications to access PMem using malloc(), mmap(), and related calls in C and C++, without modifying the application.
CLI-based tools to manage memory services, view the status of memory allocation, and run applications under Memory Machine management.
CLI-based tools to capture and organize snapshots of running processes. Time to complete a snapshot is typically under a second and is relatively independent of the in-memory size of the application. (Advanced Edition only.)
Memory Machine Management Center, a web UI application that enables you to view PMem and DRAM usage and to capture and restore snapshots. (Snapshots in Advanced Edition only.)
