| **Hard Disk**: | 100 Gb  | 1000 Gb |

### TCP/UDP PORTS

You'll need to open the following ports in both ways to deploy a node:

#### Validator Node

| Port  | Type |      To       | Definition                                   |
| :---: | :--: | :-----------: | :------------------------------------------- |
| 30303 | TCP  |    0.0.0.0    | Ethereum client listener and discovery ports |
| 30303 | UDP  |    0.0.0.0    | Ethereum client listener and discovery ports |


#### Regular/RPC Node

| Port  | Type |                 To                  | Definition                                   |
| :---: | :--: | :---------------------------------: | :------------------------------------------- |
| 30303 | TCP  |               0.0.0.0               | Listener and discovery ports                 |
| 30303 | UDP  |               0.0.0.0               | Listener and discovery ports                 |
| 8545  | TCP  | 0.0.0.0 (this can be internal only) | RPC HTTP Port                                |
| 8546  | TCP  | 0.0.0.0 (this can be internal only) | RPC WS Port                                  |
