# System Requirements

## Hardware requirements

Minimum hardware requirements for the application are the following:

* 32-bit CPU
* 1 CPU cores (recommended 2 CPU)
* 2 GB of RAM (recommended 4 GB)
* 5 GB of Hard Disk (to be dimensioned according to the archived files)

## Software requirements

### Operating system

All solution components are supported on:

* **Linux** with kernel version 4.18+
* **Windows Server** 2012+

The solution may operate on another operating system, but we recommend asking for a certification.

### Database

The product requires a database to store configuration and runtime data.\
Two installation options are available:

* **embedded database** (H2) - the database is integrated within the application and does not require external setup.
* **external PostgreSQL 16.3 and 16.x database** - the product can connect to an external PostgreSQL instance; the PostgreSQL instance must be installed, configured and available before product setup.

### Web client

Access to the application requires an Internet browser.

Currently supported browsers are:

* Google Chrome 124+
* Mozilla Firefox 126+

The solution may operate on other browsers, but we recommend working exclusively on the supported ones.

### Client versions

The following client versions are certified with **Data Mover Smart**:

* **FileZilla**: 3.66.5
* **WinSCP**: 6.5.6

### Compatibility command line

[Compatibility CLIs](/data-mover-smart/command-line-interfaces/compatibility-command-line-interfaces.md) are provided to ensure backward compatibility with legacy automation and operational scripts.

#### curl availability

The compatibility command line interfaces rely on the `curl` utility. `curl` must be installed and accessible from the system execution path of the user or service running the commands.

### Scripts execution via DMS Actions

When scripts executed through [DMS Actions](/data-mover-smart/rules/actions.md) make use of environment variables, for example the `SPAZIO` variable in the context of legacy Spazio MFT/S compatibility, these variables can be defined either in the **Data Mover Smart environment** (see the [Environment variables](/data-mover-smart/settings/advanced/environment-variables.md) page) or at the **operating‑system level**.
