    This section describes some of the services that can be run on a node.
  - Cluster Design Objectives
    This section describes some of the work that your cluster performs, and identifies key design considerations.
  - Minimum Cluster Size
    Provides considerations for smaller clusters.
  - Cluster Hardware
    Describes important hardware-architecture considerations for your cluster.
  - Service Layout in a Cluster
    Provides an overview of segregating services on different nodes.
    - Node Types
      Depending on the size of your cluster, nodes may or may not perform specialized work.
    - Service Layout Guidelines for Large Clusters
      Describes how to install and segregate services on large clusters.
    - Service Layout Guidelines for Replication
      Based on the use case, replicating HPE Ezmeral Data Fabric Database tables and HPE Ezmeral Data Fabric Streams may require the installation of Data Fabric Gateways and the HBase client on one or more nodes.
    - Data Fabric Monitoring Storage Options
      Describes various storage options for Data Fabric Monitoring. The Control System relies on Data Fabric monitoring components to display metrics, but can function without the monitoring components. Using Data Fabric monitoring to store logs is optional.
    - Example Cluster Designs

Data Fabric Monitoring Storage Options

Describes various storage options for Data Fabric Monitoring. The Control System relies on Data Fabric monitoring components to display metrics, but can function without the monitoring components. Using Data Fabric monitoring to store logs is optional.

The following installation options are available for metric storage with OpenTSDB and log storage with Elasticsearch. You can store logs and metrics on a non-Data Fabric cluster but this scenario is not supported by Data Fabric.

Store Metrics and Logs on the Monitored Cluster

You can store metrics and logs on the nodes in the same Data Fabric cluster that you want to monitor. Note that installing Grafana is optional.

Store Metrics and Logs on a Storage Cluster

You can store metrics and logs for the Data Fabric cluster that you want to monitor, on nodes in a different Data Fabric cluster.

In this case, Kibana and Grafana can be installed on either cluster.

Use a Single Cluster to Store Monitoring Data for Multiple Clusters

You can store metrics and logs for more than one Data Fabric cluster on a shared set of nodes. With this option, a single dashboard can monitor multiple clusters.

In this case, Kibana and Grafana can be installed on any of these clusters.
