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
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.
