Admin Network topology

Optionally, you can use an Admin Network and a Grid Network. For example, you can configure a routable Grid Network and a bounded Admin Network for each node.

When you configure the Admin Network, you establish the host IP address, subnet mask, and Gateway IP address for the eth1 interface for each grid node. During configuration, you create a list of subnets called the Admin External Subnet List (AESL). The AESL lists the subnets with external hosts that talk to grid nodes over the Admin Network.

At installation of the Admin Network, a static route is generated automatically for all subnets in the AESL.

In this example, the Grid Network is used for traffic related to S3 and Swift client requests and object management. while the Admin Network is used for administrative functions.
