    AMM Implementation Requirements

    The AMM is normally installed:

    1. as a virtual machine on a customer supplied server running VMware
    2. or as a customer supplied virtual machine in the AWS EC2 cloud.

    For certain situations, an appliance may be installed. More information about appliances can be seen here.

    The following subsections describe the technical requirements for these options.

    Virtual Machine Requirements

    The AMM VM virtual machine has the following requirements:

    • VMware ESXi 6.0 or higher.
    • The VM instance specification is :
    Connected Devices Reserved CPU Cores/Threads 2.1GHz or higher Reserved RAM Memory (GB) Storage
    Up to 200 4 12 See Storage Requirements for disk storage requirements.
    200-2000 8 24 See Storage Requirements for disk storage requirements.
    2000-3000 12 48 See Storage Requirements for disk storage requirements.
    3000-5000 20 96 See Storage Requirements for disk storage requirements.
    Connected Devices Reserved CPU Cores/Threads 2.1GHz or higher Reserved RAM Memory (GB) Storage
    Up to 200 4 8 3TB minimum for AMM/100GB minimum for AM
    200-2000 8 16 6TB minimum for AMM/200GB minimum for AM
    2000-3000 12 32 9TB minimum for AMM/300GB minimum for AM

    Note : These values are guidelines based on lab tests. Real world environments can be very different. Some factors that can affect these values are :

    • are the gateways running 24x7?
    • are the gateways stationary or moving?
    • what types of reports are being generated and how often?
    • how many concurrent users?

    Note : The minimum system RAM required is 12GB. The RAM amount configured by VMware UI may differ from the expected memory total. This may affect the result when it is compared to the MinMemory parameter in amm.cfg and is noticeable when trying to configure an AMM to run on a system with less than the recommended 12GB of memory. It is recommended that the VMware configuration be set to 16GB in this scenario, or the system may not function well.

    AWS EC2 Support

    AMM 2.16+ is released in the AWS EC2 cloud as a shared private image. To be able to access the image, send a request to Support so they can link the EC2 user accounts with it. The image can be used to launch multiple EC2 instances in EC2 management console. For additional information see Creating and Deploying an Amazon Machine Image .

    It is recommended that GP3 or better NVMe backed storage types be used.

    The following table lists the number of supported gateways for various hosted solutions using EC2:

    Note : These values are based on lab tests. Real world environments can be very different. Some factors that can affect these values are :

    • are the gateways running 24x7?

    Disk storage applies to all configurations. Where the expected disk storage for a deployment is greater than the standard configuration, Sierra Wireless will provide information on additional disk storage requirements. This must be requested in advance of deployment.

    External Network Access

    The AMM must be network-accessible to the gateways it manages.

    For web-based features such as maps, the AMM must be able to access the Internet.

    Simple AMM Networking Method

    For gateways that employ standard data plans that communicate over the Internet, the AMM must have a publicly accessible fully qualified domain name (FQDN) and corresponding unique public IPv4 address.

    For example, an AMM hosted by Sierra Wireless uses:

    amm01.airlink.com
    

    Advanced AMM Networking Method

    For gateways that employ a private networking cellular service from a carrier and optionally employ a second WAN interface such as Wi-Fi, network access to the AMM must still be provided. The network design and implementation for this method is outside the scope of this document. However the end result is that the AMM is typically assigned a private address and host name within the enterprise.

    Firewall Considerations

    The AMM has an integrated firewall that defends against unauthorized access and therefore it may be installed with direct access to the Internet. However the AMM may also be installed behind a firewall provided that certain ports are made accessible through the firewall.

    Refer to Firewall Considerations for IP ports required by AMM.

    Internal Network Access

    In order for operations staff to use the management functions of the AMM, their workstations must be able to access the AMM server.

    If operators reside outside the facility where the AMM is installed, this section may not apply.

    If your operators reside within the same facility (i.e. on the same enterprise network) as the AMM, the AMM server will be directly connected to the enterprise network. In this case the AMM must be assigned a unique internal name and IP address to the AMM. This may require an internal DNS server to be changed so that user workstations can locate the AMM.

    Operator Station Requirements

    The AMM provides a graphical user interface for operators to access management functions via a web browser.

    The AMM is certified to operate with PC workstations running various browsers listed below in Supported Browsers.

    The AMM user interface is not designed to operate on tablets or smart phones.

    The web browsers must have cookies and Javascript enabled.

    Some features of the AMM such as maps, integrate local data produced from the server with remote web-based data. Maps are used primarily for location-based coverage reports and require that user desktops be able to access the following map services:

    • For oMM versions below 2.12: Microsoft Maps (dev.virtualearth.net)
    • For oMM 2.12 and above: Google Maps (maps.googleapis.com). See Google Map Requirements for more information.

    ALEOS Communication to the AMM

    It is highly recommended that ALEOS devices are configured for secure communication using HTTPS. In order to configure the AMM for secure communications to ALEOS devices, certificates need to be installed.

    For more information about the required certificates, see Certificate Considerations for ALEOS and AMM Communication.

    Once the certificates have been installed on the AMM, the ALEOS gateways need to be configured for secure communication over HTTPS. For more information about how to configure this, see ALEOS Gateways Over HTTPS.

    ALEOS devices can be configured in a variety of ways to send specific information when reporting to an AMM. For more information about this, see Configuring ALEOS Devices for AMM Servers.

    MG Re-Homing

    MGs can be configured to home in onto a particular AMM explicitly. However, Sierra Wireless recommends that the default MG behavior be relied upon to perform an automatic location look-up of a unit’s designated AMM via DNS.

    Note: this requires that access to an external DNS service is available and therefore may not work for private-only networks.

    The DNS-based location method uses a high-availability DNS service managed by Sierra Wireless. This DNS service is the authority for the omgservice.com domain. Gateways that use automatic lookup discover their AMM by resolving their serial number within the omgservice.com domain. For example:

    H1301111G0001.omm.omgservice.com
    

    would refer to omm01.inmotionsolutions.net.

    The target AMM should be determined prior to deploying gateways by contacting Support and requesting DNS redirects for the units in question.

    If the recommended DNS-based method is anticipated, it may affect where you physically locate the AMM (so it connects to the appropriate network segment within your enterprise) and influence your naming and addressing choices. For example, your AMM may need to be explicitly included in your APN configuration by your service provider.

    High Availability Requirements

    The hardware specifications includes support for high availability. For more information about high availability, see High Availability.
