System Requirements

The system requirements for Hyperledger Besu depend on a number of factors:

  • Size of the world state for the network
  • Number of transactions submitted to network
  • Block gas limit
  • Number and complexity of JSON-RPC, PubSub, or GraphQL queries being handled by the node

Determining System Requirements

To determine system requirements, monitor CPU and disk space requirements using Prometheus. A sample Grafana dashboard is provided for Besu.

Tip

CPU requirements are highest when syncing to the network and typically reduce once the node is synchronized to the chain head.

RAM

Besu requires 4GB of RAM. For Ethereum Mainnet, a minimum of 8GB of RAM is required.

Disk Space

Syncing to the Ethereum Mainnet requires 3TB for a full sync. To reduce the requirement, use pruning. With pruning, we recommend approximately 700GB of available disk space.
