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

For detailed information about network requirements between vPlus solution and supported platforms see Platform 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.
