2.1. About DX Storage in the Network

The following topics in this section provide a high-level overview of setting up a DX Storage cluster

in your network:

•

Section 2.1.1, “Sample Networks”

•

Section 2.1.2, “Layer 3 Switching and Routing”

•

Section 2.1.3, “Switching Hardware”

•

Section 2.1.4, “Internet Deployments”

2.1.1. Sample Networks

The following figure shows a basic network where the DX Storage cluster nodes, the clients, and

the servers are all in the same subnet. While this is the easiest to setup and requires only basic

hardware, it does not offer any traffic separation between the DX Storage nodes and the rest of the

network.
