Nodes are the hardware that is grouped into a cluster to be accessed as block storage or compute resources.
More information
NetApp HCI storage nodes NetApp HCI storage nodes are hardware that provide the storage resources for a NetApp HCI system. Drives in the node contain block and metadata space for data storage and data management. Each node contains a factory image of NetApp Element software. NetApp HCI storage nodes can be managed using the NetAppElement Management extension point.
NetApp HCI compute nodes NetApp HCI compute nodes are node hardware that provide the resources, such as CPU, memory, and networking, that are needed for virtualization in the NetApp HCI installation. Because each server runs VMware ESXi, NetApp HCI compute node management (adding or removing hosts) must be done outside of the plug-in within the Hosts and Clusters menu in vSphere.
SolidFire Storage nodes
A SolidFire all-flash array storage node is a collection of drives that communicate with each other through the CIPI Bond10G network interface. Drives in the node contain block and metadata space for data storage and data management. You can create a cluster with new storage nodes, or add storage nodes to an existing cluster to increase storage capacity and performance.
SolidFire Fibre Channel nodes
SolidFire Fibre Channel nodes provide connectivity to a Fibre Channel switch, which you can connect to Fibre Channel clients. Fibre Channel nodes act as a protocol converter between the Fibre Channel and iSCSI protocols; this enables you to add Fibre Channel connectivity to any new or existing SolidFire cluster.
Adding a node to a cluster
You can add storage nodes when a cluster is created or when more storage is needed.
Node details
You can view a list of the nodes in the cluster on the Nodes page of the Cluster tab from the NetApp Element Management extension point. You must select Active view to see the list of active nodes. You can change the view by selecting Pending, PendingActive, and All options using the drop-down filter.
Removing nodes from a cluster
You can remove nodes from a cluster without service interruption when their storage is no longer needed or they require maintenance.
Restarting cluster nodes
You can restart one or more active nodes in a cluster using the NetAppElement Management extension point.
Shutting down cluster nodes
You can shut down one or more active nodes in a cluster using the NetAppElement Management extension point. To shut down the cluster, you can select all cluster nodes and perform a simultaneous shutdown.
