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

For optimal performance up to 40 agents:

  • 4 CPU cores
  • 6 GB of RAM (+6 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.

Note

We can't suggest any disk space recommendations, as this highly depends on how you work. Zammad will always try to recognize the same attachments and store it just once.
