Managing clusters

You can use Storage Manager to manage clusters.

  • 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 Storage 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 Storage 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 Storage Manager .
  • Cluster peers
    Peered clusters are required for data replication using SnapMirror technology and SnapVault technology, and for data replication using SyncMirror technology in MetroCluster configurations. You can use Storage Manager to peer two clusters so that the peered clusters can coordinate and share resources between them.
  • High availability
    You can use Storage Manager to create high availability (HA) pairs that provide hardware redundancy that is required for nondisruptive operations and fault tolerance.
  • Licenses
    You can use Storage Manager to view, manage, or delete any software licenses installed on a cluster or node.
  • Cluster Expansion
    You can use Storage 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 Storage Manager to update a cluster or the individual nodes in an high-availability (HA) pair. To perform an update, you should select an ONTAP image, validate that your cluster or the individual nodes in the HA pair are ready for the update, and then perform the update.
  • Date and time settings of a cluster
    You can use Storage Manager to manage the date and time settings of a cluster.
  • SNMP
    You can use Storage Manager to configure SNMP to monitor SVMs in your cluster.
  • LDAP
    You can use Storage Manager to configure an LDAP server that centrally maintains user information.
  • Users
    You can use Storage Manager to add, edit, and manage a cluster user account, and specify a login user method to access the storage system.
  • Roles
    You can use Storage Manager to create access-controlled user roles.
