In the production environment, the `TiDB` and `PD` instances can be deployed on the same server. If you have a higher requirement for performance and reliability, try to deploy them separately.

It is strongly recommended to use higher configuration in the production environment.

In TiDB v6.5, it is recommended to keep the size of `TiKV` hard disk within 2 TB if you are using `PCIe SSD` or within 1.5 TB if you are using regular `SSD`.
