Note: IBM Storage Defender support for third-party operating systems, applications, services, and hardware depend on the respective vendor. If a third-party product or version moves into extended support, self-service support, or end-of-life, IBM Storage Defender supports the product or version at the same level as the vendor. See also IBM Support General Guidelines and Limitations - IBM support for software on unsupported operating systems.



 

Requirements for IBM Storage Defender connection manager

The IBM Storage Defender Data Resiliency Service connection manager (connection manager) is used to connect your local storage and backup systems and your Data Protect cluster to Data Resiliency, to do inventory operations and also to do test recovery and recovery operations by using Data Resiliency.  

Inside the connection manager, Red Hat® Enterprise Linux® is used as the operating system. The connection manager software is built to require less configuration and connect to your local resources and the Data Resiliency Service that runs in the cloud.  
You can connect IBM Storage Defender Data Resiliency Service (Data Resiliency) to your on-premises resources by deploying a connection manager either on a VM or on a bare metal server. The connection manager section in the Data Resiliency Service user interface helps you to create and update the connection manager.   
 

  • Add a connection manager   
    The corresponding connection manager ISO file be deployed in a virtual machine or on a bare metal server. For more information, see Adding a connection manager.
    The minimum hardware requirements are:

    Hardware
    System- Systems based on the x86 64-bit architecture such as Intel-64 or AMD-64
    - VMware virtual hardware version: v19 and later
    Processor- 4-core central processing unit (CPU)
    - Physical or virtual CPU that supports x86-64-v3 microarchitecture specification
    Disk space256 GB of disk space
    Memory16 GB Random Access Memory (RAM)


     

  • Update an installed connection manager  
    To update the installed connection manager check the connection manager section in the Data Resiliency. In this section you can check if any new updates for the connection manager are available.
    • You can perform a offline update to the latest available version. For more information, see Updating connection manager offline.
    • For connection managers with versions 2.0.10 and later, you can also set the preference to update the connection manager to the latest version either as automatic or on demand by editing the update settings. For more information, see Updating connection manager.    
      To run the automatic update, the connection manager must have outbound network connectivity to the online update server hosted in Amazon Web Services CloudFront content delivery network (CDN). If the connection manager is deployed in a network that has an outbound firewall, make sure that it is configured to allow outbound connections from the connection manager to host *.cloudfront.net on HTTPS port 443.  
       
  • Network connections to the connection manager  
    The connection manager collects metadata about your storage and backup systems as described in Inventory metadata that is collected from Data Resiliency.  It also performs data movement when recovering VMware virtual machines from backups on an IBM Storage Protect server.  Network connections to the connection manager should be sized based on how it will be used.

     Minimal requirementPreferred
    Network1 Gigabit Ethernet (GbE)10 Gigabit Ethernet (GbE)

    Notes:

    • If you do not have IBM Storage Protect in your environment, or do not use IBM Storage Protect to backup VMware virtual machines, then the connection manager must have at least the minimal network requirements.
    • If you use the connection manager to recover VMware virtual machines from IBM Storage Protect, then you should configure the network connection to the connection manager with the preferred network requirements.  You should also connect the connection manager to a network that is close to the IBM Storage Protect server and the clean room to which you will recover your virtual machines. 
    • For a detailed list of network connections required for the connection manager to function as a source or a target, see IBM Storage Defender Data Resiliency Service: Network requirements.
       
  • Connection manager supported sensors  
    For the minimum hardware requirements the supported virtual machines with sensors are:  
    - maximum 3000 virtual machines with sensors, or  
    - maximum 1000  virtual machines with sensors  (If you are using IBM Storage Protect to restore VMware virtual machines)  
    If you want to support more sensors, you can add CPU cores to your system.  
    The following table displays the connection manager system resources usage:

    HardwareSystem resources usage
    Minimum hardware requirements:  
    4-core processor and 16 GB RAM 
    - 1 core and 8 GB RAM used  for general compute use   
    - 1 core and 1 GB RAM per 1000 virtual machines with sensors   
    - 2 cores and 2 GB RAM allocated for IBM Storage Protect VM's restore processing
    Example for hardware requirements:   
    8-core processor and 128 GB RAM
    - 1 core used for general compute use  
    - 5 cores used for up to 5000 virtual machines with sensors   
    - 2 cores  allocated for IBM Storage Protect VM's restore processing


 

Requirements for IBM Storage Defender sensor control node

IBM Storage Defender implements the concept of sensor control nodes. The sensor control nodes are used to host the sensor management systems. The sensor management systems are used for sensors that get installed on resources like virtual machines. For more information, see in the IBM Documentation the sensor control architecture illustration.

IBM Storage Defender sensor control node requires the following software:

Software
Operating systemRed Hat Enterprise Linux Server 9
Automation software applicationAnsible Playbook Software (command: ansible-playbook)  
Note: Ansible collection Community.General should be installed.


 

Requirements for IBM Storage Defender sensors

The sensor is installed on VMware virtual machines. The sensor software is hosted by the sensor control node and distributed to those virtual machines where the sensor is to be installed. The sensors observe the systems that they are installed on and can detect cyberattacks like ransomware attacks in real time. When the sensor detects cyberattacks, the sensor alerts you by sending messages to the on-premises connection manager and Data Resiliency Service.
