Component Requirements

System requirements

Operating System

  • CentOS Linux stream

  • Red Hat Enterprise Linux 8.x

  • Red Hat Enterprise Linux 9.x

  • Oracle Linux 8.x

  • Oracle Linux 9.x

  • AlmaLinux 8.x

  • AlmaLinux 9.x

  • Rocky Linux 8.x

  • Rocky Linux 9.x

  • SUSE Linux Enterprise Server (SLES) 15

Note.

  • AlmaLinux 9.x is the recommended operating system for optimal performance and compatibility.

  • Using Red Hat Enterprise Linux requires an active subscription.

  • Minimal installation is required.

Hardware Requirements

Minimum requirements for all-in-one installation (vPlus server and node on the same host):

  • 64-bit 8 cores processor

  • 10 GB RAM

  • 20GB free disk space for the operating system and vPlus installation

  • Free disk space for data staging

    • You can estimate the free space requirement using the following equation: (Size of the biggest virtual machine) * (number of parallel backup threads)

Minimum requirements for vPlus server (standalone installation):

  • 64-bit 4 cores processor

  • 4 GB RAM

  • 20GB free disk space for the operating system and vPlus installation

Minimum requirements for vPlus node (standalone installation):

  • 64-bit 4 cores processor

  • 6 GB RAM

  • 20GB free disk space for the operating system and vPlus installation

  • Free disk space for data staging

    • You can estimate the free space requirement using the following equation: (Size of the biggest virtual machine) * (number of parallel backup threads)

General network requirements

Communication between node and server

Source
Destination
Ports
Description

Node

Server

443/tcp or 8181/tcp

Node <-> Server communication over HTTPS (port 443 or 8181)

Server

Node

111/tcp, 111/UDP, 2049/tcp, 2049/UDP, ports specified in /etc/sysconfig/nfs - variables MOUNTD_PORT (TCP and UDP), STATD_PORT (TCP and UDP), LOCKD_TCPPORT (TCP), LOCKD_UDPPORT (UDP)

NFS access to browse mountable backups and logs from administrative portal (using IP that is detected as the source IP - shown in the Node list in the portal)

Network consideration

  • Depending on where the node is located you need to verify if data will not pass via low-bandwidth links.

  • Access to the internet network from the node may be required in the following scenarios:

    • Installation, when using the external repositories

    • Backup and restore of Amazon EC2, Google Cloud Platform, Azure Cloud and M365

  • vPlus Node requires connectivity with backup destinations

  • vPlus Node needs connectivity with the Hypervisor or Hypervisor Manager.

  • If a netcat transfer is used for Red Hat Virtuallization/oVirt/Oracle Linux VM/Proxmox VE/KVM standalone environments - 16000–16999 ports must be reachable from the hypervisors to the node which is responsible for those hypervisors.
