Networking overview

After you determine the topology of your network, you can set up and manage your internal and external networks.

There are two types of networks on a cluster:

Nodes communicate with each other using a high speed low latency InfiniBand network. You can optionally configure a second InfiniBand network to enable failover for redundancy.
Clients connect to the cluster through the external network with Ethernet. The Isilon cluster supports standard network communication protocols, including NFS, SMB, HDFS, HTTP, and FTP. The cluster includes various external Ethernet connections, providing flexibility for a wide variety of network configurations.
