# Server requirements

> Hardware, software, and network requirements for installing the Cognite PI extractor.

You can install the extractor on a physical server, on a virtual machine on-premises, or in the cloud.

## Memory

For the default values in the configuration, the server needs a minimum of 4 GB RAM and an additional 256 GB HD for logging and storage. You can adjust the configuration to reduce memory usage.

## CPU

For the default values in the configuration, the server needs a minimum of **2-core CPUs**.

<Info>
  The memory and CPU requirements also depend on the number of PI points in the PI Data Archive, the rate of real-time data points, the volume of historical data, and the rate at which the extractor checks for new PI Points.
