1.2. Hardware Requirements for ABGW-only Installations

Normally, Acronis Cyber Infrastructure is installed on at least five nodes to fully utilize its built-in high availability and data redundancy capabilities. However, if you only want to use the ABGW feature, you can deploy a very basic installation on a single virtual or physical node. Although in this case you may need to provide data redundancy by other means or risk losing user data. You can do the following:

  • Use a virtual machine (VM) with at least two virtual HDDs (three are recommended). In this case, only one HDD will be used for data storage and you may need to make sure that the VM is made redundant by the virtualization solution it runs on.
  • Use a physical server with at least two disks (three are recommended). Have in mind that you will need to use more disks for storage to enable data redundancy. For more details on how to plan your server configuration, see the Installation Guide.

Other minimal requirements are:

  • 120 GB or higher capacity of each HDD/SSD


    If you plan to use Backup Gateway to store backups in the cloud, make sure the local storage cluster has plenty of logical space for staging (keeping backups locally before sending them to the cloud). For example, if you perform backups daily, provide enough space for at least 1.5 days’ worth of backups. For more details, see the Administrator’s Guide.

  • 4 logical CPUs*

  • 4GB RAM**

  • 1GbE network interface with a static IP address. You can also use the same network interface for both internal and external traffic (but you are advised to configure secure networking later).

* A logical CPU is a core (thread) in a multicore (multithreading) processor.

** Each chunk server (CS), e.g., storage disk, requires 1 GB of RAM (0.5 GB anonymous memory + 0.5 GB page cache). The total page cache limit is 12 GB. In addition, each metadata server (MDS) requires 0.2 GB of RAM + 0.1 GB per 100TB of physical storage space.
