Some compiler optimizations that would be valid in single-threaded programs are not valid in all Go programs.

it must not allow a single read to observe multiple values,
and it must not allow a single write to write multiple values.

## 1. Standalone Deployment

To host multiple tenants on a single machine, run one MinIO Server per tenant with a dedicated HTTPS port, configuration, and data directory.

### 1.1 Host Multiple Tenants on a Single Drive

Use the following commands to host 3 tenants on a single drive:

```sh
minio server --address :9001 /data/tenant1
minio server --address :9002 /data/tenant2
