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)
- You can estimate the free space requirement using the following equation:
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)
- You can estimate the free space requirement using the following equation:
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.
