Nodes

Contributors netapp-pcarriga

From the Nodes page, available from the side panel for a selected cluster, you can view information for the nodes in your cluster.

The available details vary based on your system:

View SolidFire storage node details

Each node is a collection of SSDs. Each storage node comes with CPU, networking, cache, and storage resources. The storage node resources are pooled into a cluster of nodes.

On the Nodes page, the information bar provides a quick overview of the following data:

  • MVIP: Management virtual IP address

  • MVIP VLAN ID: Virtual LAN ID for the MVIP

  • SVIP: Storage virtual IP address

  • SVIP VLAN ID: Virtual LAN ID for the SVIP

View information about storage nodes

The following information is available for each storage node in the cluster:

Heading Description

ID

System-generated ID for the node.

Status

The status of the node:

  • Healthy: The node has no critical errors associated with it.

  • Offline: The node cannot be accessed. Select the link to view the Error Log.

  • Fault: There are errors associated with this node. Select the link to view the Error Log.

Name

The system-generated node name.

Type

Displays the model type of the node.

Version

Version of Element software running on the node.

Serial Number

Unique serial number assigned to the node.

Management IP

Management IP MIP address assigned to node for 1GbE or 10GbE network admin tasks.

Cluster IP

Cluster IP address assigned to the node used for the communication between nodes in the same cluster.

Storage IP

Storage IP address assigned to the node used for iSCSI network discovery and all data network traffic.

Average Throughput Last 30 mins

Sum of average throughputs executed in the last 30 minutes against all volumes that have this node as their primary.

Average IOPS Last 30 mins

Sum of the average number of IOPS executed in the last 30 minutes against all volumes that have this node as their primary.

Average Latency (µs) Last 30 mins

The average time in microseconds, as measured over the last 30 minutes, to complete read and write operations to all volumes that have this node as their primary. To report this metric based on active volumes, only non-zero latency values are used.

Role

Identifies what role the node has in the cluster:

  • Cluster Master: The node that performs cluster-wide administrative tasks and contains the MVIP and SVIP.

  • Ensemble Node: A node that participates in the cluster. There are either three or five ensemble nodes depending on cluster size.

  • Fibre Channel: An FC node in the cluster.

  • If a node does not have a role, the value is set to - (dash).

View NetApp HCI storage and compute node details

For NetApp H-series nodes, which comprise a NetApp HCI system, there are two types: compute and storage nodes.

On the Nodes page, the information bar provides a quick overview of the following data:

  • MVIP: Management virtual IP address

  • SVIP: Storage virtual IP address
