Understanding quorum and epsilon
Quorum and epsilon are important measures of cluster health and function that together indicate how clusters address potential communications and connectivity challenges.
Dashboard window
The Dashboard window contains multiple panels that provide cumulative at-a-glance information about your system and its performance.
Applications
You can use predefined application templates in System Manager to create new configurations that are based on existing application templates. You can then provision instances of the application in ONTAP.
Configuration update
You can use System Manager to configure the administration details of storage virtual machines (SVMs).
Service Processors
You can use a Services Processor to monitor and manage your storage system parameters such as temperature, voltage, current, and fan speeds through System Manager.
Cluster peers
Peered clusters are required for data replication using SnapMirror technology and SnapVault technology, and for data replication using FlexCache volumes and SyncMirror technology in MetroCluster configurations. You can use System Manager to peer two clusters so that the peered clusters can coordinate and share resources between them.
High availability
You can use System Manager to create high availability (HA) pairs that provide hardware redundancy that is required for nondisruptive operations and fault tolerance.
Licenses
You can use System Manager to view, manage, or delete any software licenses installed on a cluster or node.
Cluster Expansion
You can use System Manager to increase the size and capabilities of your storage by adding compatible nodes to the cluster and configuring the node network details. You can also view the summary of the nodes.
Updating clusters
You can use System Manager to update a cluster or the individual nodes in a high-availability (HA) pair. You can also update a cluster in a MetroCluster configuration.
MetroCluster switchover and switchback
Starting with System Manager 9.6, you can use MetroCluster switchover and switchback operations to allow one cluster site to take over the tasks of another cluster site. This capability allows you to facilitate maintenance or recovery from disasters.
