# Recommended hardware configuration

This section describes the recommended hardware configurations for using Qlik Replicate. For information on the software requirements for using Qlik Replicate, see [Installing Qlik Replicate](https://help.qlik.com/en-US/replicate/November2025/Content/Replicate/Main/Installation/Install_Replicate.htm#ar_installation_558397570_1700422).

The following table describes the recommended hardware configuration for installing Qlik Replicate on Windows and Linux operating systems. Note that the recommendations apply to mid-scale systems (i.e. hundreds of tasks) rather than large-scale systems (i.e. thousands of tasks).

Recommended hardware configurations

|  | Basic System | Large System | Extra-Large System | Notes: |
| --- | --- | --- | --- | --- |
| Processor | Quad core | Quad core base<br><br>Dual-core per task | 8-core base<br><br>Quad core per task | Additional cores are useful in any of the following situations:<br><br><ul> <li>Many tasks running in parallel</li> <li>Full-load performance priority</li> <li>Multiple full-load processes running in parallel</li> </ul> |
| Memory | 8 GB | 32 GB | 64 GB | More memory is useful in any of the following situations:<br><br><ul> <li>Many tasks running in parallel</li> <li>Long-running transactions on the source endpoint (for example, monthly batch processing)</li> <li>Many active users on the source system</li> </ul> |
| Disk requirements (SSD is recommended for optimal performance) | 320 GB | 500 GB<br><br>RAID | 500 GB<br><br>RAID | A faster disk is useful in any of the following situations:<br><br><ul> <li>Using a file-based target.</li> <li>Long-running source transactions that may not fit into memory</li> <li>Using tasks that are set up to continue processing during target outage</li> </ul><br><br>A larger disk is required in any of the following situations:<br><br><ul> <li>Using tasks that are set up to continue processing during target outage</li> <li>Very large source transactions that do not fit into memory</li> </ul><br><br>RAID is recommended for system recovery in case of disk failure for all configurations. |
