Hardware

You can run Zammad on bare metal or on a virtual machine. Choose what you prefer.

For Zammad and a database server like PostgreSQL we recommend at least:

  • 2 CPU cores
  • 2 GB of RAM (+2 GB if you want to run Elasticsearch on the same server)

For optimal performance up to 40 agents:

  • 4 CPU cores
  • 4 GB of RAM (+4 GB if you want to run Elasticsearch on the same server)

Of course at the end it depends on acutal load of concurent agents and data traffic.
