Clients connect to the cluster using Ethernet connections (10, 25, 40 or 100 GbE) that are available on all nodes. Because each node provides its own Ethernet ports, the amount of network bandwidth available to the cluster scales linearly with performance and capacity. The cluster supports standard network communication protocols to a customer network, including NFS, SMB, HTTP, FTP, HDFS, and S3 object, plus full IPv4 and IPv6 support.
