# Erasure code sizing guide

## Toy Setups

Capacity constrained environments, MinIO will work but not recommended for production.

- On baremetal setups, if you have `MINIO_VOLUMES="http://minio{1...2}/data{1...4} http://minio{3...4}/data{1...4}"`, you can remove the first argument `http://minio{1...2}/data{1...4}` to update your `MINIO_VOLUMES` setting, then restart all the servers in the setup in parallel using `systemctl restart minio`.

specifying that you want to use the TLS secret: ```bash helm install --set tls.enabled=true,tls.certSecret=tls-ssl-minio minio/minio ``` ### Installing certificates from third party CAs MinIO can connect to other servers, including MinIO nodes or other server types such as NATs and Redis. If these servers use certificates that were not registered with a known CA, add trust for these certificates to MinIO Server by bundling these certificates into a Kubernetes secret and providing it to Helm via the `trustedCertsSecret`...
