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.
Managing Applications
You can view application instances from the Applications Console. Application instances must be started and stopped using the command line.
Reconfiguring an Application Instance
Change the DRAM and HugePage settings for an application instance while it is running on the Configuration Details Tab of the Applications Console.

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.
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.
- Getting Familiar with the Memory Machine Management Center
  Memory Machine Management Center (M3C) is a web-based user interface (UI) from which an administrator can view memory and processor statistics and capture and restore application snapshots on any number of servers under management by Memory Machine.
- Managing Hosts
  Use the Hosts Console to manage hosts and to view statistics about application instances, memory performance, and snapshots on individual hosts and host groups.
- Managing Applications
  You can view application instances from the Applications Console. Application instances must be started and stopped using the command line.
  - Creating an Application Instance
    Run a new application, or a new instance of an existing application, from the command line.
  - Removing an Instance
    Remove an instance from Memory Machine Management Center by stopping the running process tree and deleting all snapshots.
  - Removing an Application
    Remove an application from Memory Machine Management Center (M3C) by removing all instances of the application.
  - Reconfiguring an Application Instance
    Change the DRAM and HugePage settings for an application instance while it is running on the Configuration Details Tab of the Applications Console.
- Using Snapshots in Memory Machine Management Center
  Use ZeroIO Snapshot from Memory Machine Management Center to capture the state of a running process. You can then stop the process and restore it to the running state captured in the snapshot.
- Viewing Metrics and System Status
  The Memory Machine Management Center makes it easy to view and compare running processes, snapshots, system resources and performance metrics.
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.

Reconfiguring an Application Instance

Change the DRAM and HugePage settings for an application instance while it is running on the Configuration Details Tab of the Applications Console.

Before you begin

Start an application instance in Memory Machine.

About this task

Do the following to change the DRAM cache size and/or turn HugePages on or off for an application instance without stopping the instance.

Procedure

In the Applications Console, choose the Configuration Details Tab.
Click Edit.

Note: The Edit icon is available only if the application instance is running. You cannot change the memory allocation of a snapshot.
Modify the DRAM cache size fields:

DRAM Tier Size value

The amount of DRAM used as tiering memory for this application instance. See The Application DRAM Tier.

DRAM Tier Size units

Units for the tier size, either megabytes (MB) or gigabytes (GB).
Optional: Change the Huge Page DRAM field to control whether HugePages are used (true) or not (false). See Configuring HugePages.
HugePage status can only be changed when DRAM tiering is off (set to zero). To change HugePage status, you must:
1. Change DRAM Tier Size to 0.
2. Save your changes.
3. Change the value of Huge Page DRAM.
4. Save your changes.
5. Change DRAM Tier Size back to its original (or a new) non-zero size value.
Click Save to save your changes.
