Survox System Requirements

Smaller environments with limited concurrency and lighter workloads may use the following reduced server configuration.

The smaller configuration is intended for installations with limited concurrency. Processor and memory resources should be increased as system usage, workload, or application requirements grow.

Actual server requirements may vary depending on how the Survox environment will be used. The following factors should be considered when planning server capacity.

Concurrent Usage

• Number of concurrent users
• Number of concurrent survey sessions
• Expected peak usage periods

Application Requirements

• Supported survey modalities
• Enabled Survox application features
• Dialer usage
• Reporting requirements
• Background processing requirements
• External integrations

System Workload

• Expected transaction volume
• Database activity
• Survey processing workload
• Scheduled processing and automated jobs

Future Capacity

• Expected growth in users or sessions
• Additional survey workloads
• Future application features
• Future scalability requirements

Survox production servers are supported on Oracle Linux 8.

All production Survox deployments should use Oracle Linux 8 to maintain compatibility, stability, and supportability.

Survox may be deployed on either physical or virtual server infrastructure provided that the system meets the appropriate resource requirements.

Virtual Server Requirements

• Allocate sufficient CPU resources for the expected Survox workload.
• Allocate the recommended amount of system memory.
• Provide at least 100 GB of available disk space.
• Use Oracle Linux 8 as the guest operating system.
• Size the virtual machine according to expected concurrency and workload.
• Allow additional capacity for future application growth.

Virtualized resources should be treated in the same manner as physical server resources when determining the appropriate Survox server size.

Asterisk 16.8 remains a viable and supported platform for existing Survox dialer installations.

Customers currently operating Asterisk 16.8 may continue using their existing installation with Survox 10.4.6 and later releases.

Asterisk 20 has been tested with Survox and is supported as a newer Asterisk platform.

Support for Asterisk 22 is planned after validation and compatibility testing have been completed.

PHP

Survox requires PHP 8.2 or higher.

Required application dependencies and supporting software are installed as part of the Survox installation process.

The standard server specification requires at least 100 GB of available disk space.

Additional storage may be required depending on the size and usage of the Survox environment. When planning storage capacity, consider:

• Survey and project data
• Sample data
• Reporting data
• Audio recordings
• Log files
• Temporary processing files
• Database growth
• Future projects and increased usage

Environments expected to retain significant amounts of audio or other large data files should provide additional storage beyond the standard 100 GB recommendation.

The Survox server should be deployed on reliable production infrastructure with adequate network connectivity for the services being provided.

Infrastructure planning should account for:

• Connectivity between users and the Survox server
• Web survey traffic
• Database connectivity
• Dialer and telephony traffic when applicable
• External integrations
• Backup infrastructure
• Monitoring and administrative access

These specifications are intended to provide a baseline for standard Survox deployments and should not be considered a maximum supported configuration.

Production environments with higher concurrency, heavier workloads, additional modalities, or anticipated future growth may require additional:

• Processor capacity
• System memory
• Storage capacity
• Network capacity
• Database resources
• Infrastructure resources

Server sizing should be reviewed whenever usage patterns, concurrency, or application requirements change significantly.

PHP

Survox requires PHP 8.2 or higher.

Required application dependencies and supporting software are installed as part of the Survox installation process.

If the server is currently running an older version of PHP, use the following procedure to update PHP on Oracle Linux 8.

1. Install the Required Packages

yum install php php-mysql php-curl php-cli
dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
dnf install yum-utils

2. Reset the Current PHP Module

dnf -y module reset php

3. Enable PHP 8.2

dnf -y module enable php:remi-8.2

4. Upgrade PHP

dnf upgrade
dnf install php php-cli

5. Verify the Installed Version

php --version

Verify that the command reports PHP 8.2 or later before continuing with the Survox installation or upgrade.
