Switch configuration for clusters running Element software
Contributors Download PDF of this page
The NetApp Element software system has certain switch requirements and best practices for optimal storage performance.
Storage nodes require 10 or 25GbE Ethernet switches, depending on specific node hardware, for iSCSI storage services and node intra-cluster services communication. 1GbE switches can be used for these types of traffic:
Management of the cluster and the nodes
Intra-cluster management traffic between the nodes
Traffic between the cluster nodes and the management node virtual machine
Best Practice: You should implement the following best practices when configuring Ethernet switches for cluster traffic:
