The StorageGRID system supports up to three network interfaces per grid node, allowing you to configure the networking for each individual grid node to match your security and access requirements. Subnets are available on each network for access restriction and protection of network segments.
Client Network: Optional. In addition to the Grid Network, you can configure an external-facing network, known as the Client Network, to allow S3 and Swift clients to access the grid. Using a Client Network, you can configure a Grid Network that is private and not externally routable, while using an external network for client access. If a Client Network is configured, the Client Network gateway becomes the default gateway for outbound connections when you complete the grid configuration steps.
You can use the untrusted Client Network feature if you want the Client Network to be more restrictive of what connections are allowed.
On each node, each network maps to a specific network interface.
Network | Interface |
---|---|
Grid Network (required) | eth0 |
Admin Network (optional) | eth1 |
Client Network (optional) | eth2 |
You can only configure one IP address/mask/gateway combination for each of the three networks on each grid node. If you do not want to configure a gateway for a network, you can use the network IP address as the network gateway address.
