    The Installer automates the process of installing Data Fabric software and offers you a variety of options to complete the installation.
  - Installing without the Installer
    Describes how to install HPE Ezmeral Data Fabric software and ecosystem components manually.
    - Step 1: (Optional) Enable FIPS Mode
      If your cluster must be FIPS-compliant, you must enable FIPS mode at the operating system level before installing Data Fabric software. If FIPS compliance is not needed, you can skip this step.
    - Step 2: Import the Package Key
      Before you install Data Fabric packages, you must import the package key.
    - Step 3: Prepare Packages and Repositories
      To install services correctly, each node must have access to the package files.
      - Using the Data Fabric Repository (Installation)
        This section describes how to make packages available through the HPE Ezmeral Data Fabric repository.
      - Using a Local Repository
        This section describes how to make packages available through a local repository.
        Creating a Local Repository on RHEL, CentOS, or Oracle Linux
        This section describes how to create and use a local repository.
        Add the repository on each node
        Each node must contain your local repository.
        Enable the EPEL repository on CentOS 6.x, RHEL 6.x, or Oracle Linux 6.4 or higher
        This section describes how to download and install the EPEL repository.
        Enable the EPEL repository on CentOS 7.x, RHEL 7.x, or Oracle Linux 7.0/7.1
        This section describes how to download and install the EPEL repository.
        Enable the EPEL repository on CentOS 8.x, RHEL 8.x, RHEL 9.x, or Oracle Linux 8.x
        This section describes how to download and install the EPEL repository.
        Creating a Local Repository on SUSE
        This section describes how to create and use a local repository.
        Creating a Local Repository on Ubuntu
        This section describes how to create and use a local repository.
      - Using a Local Path with rpm or deb Package Files
        This section describes how to make packages available through a local path.
    - Step 4: Install Cluster Service Packages
      The installation process varies based on the location of your packages and the configuration of your cluster.
    - Step 5: Verify Installation Success
      To confirm success, check each node.
    - Step 6: Set Environment Variables
      Before starting ZooKeeper or Warden, you must complete this step.
    - Step 7: Configure Nodes
      Connect nodes to the cluster, configure security, and arrange node storage.
    - Step 8: Bring up the Cluster
      Before you can install monitoring or ecosystem components, you must enable the cluster by starting ZooKeeper and Warden and verifying the cluster installation status.
    - Step 9: Install Metrics Monitoring
      Metrics monitoring is part of monitoring, which also includes log monitoring. Monitoring components are available as part of the Ecosystem Pack (EEP) that you selected for the cluster.
    - Step 10: Install Log Monitoring
      Installing the monitoring logging components is optional. The logging components enable the collection, storage, and visualization of core logs, system logs, and ecosystem component logs. Monitoring components are available as part of the Ecosystem Pack (EEP) that you selected for the cluster.
    - Step 11: Install Ecosystem Components Manually
      You can install one or more ecosystem components from any Ecosystem Pack (EEP) that is supported by the Data Fabric cluster version. An EEP consists of a group of ecosystem components that work together.
    - Step 12: Run configure.sh
      Run configure.sh with the -R option to complete the configuration of ecosystem components that were added manually.
  - Configuring the Cluster
    Describes post-installation configuration tasks for HPE Ezmeral Data Fabric clusters.
- Installing the HPE Ezmeral Data Fabric File Store
  Describes how to install File Store software with or without the Installer.
- Installing the HPE Ezmeral Data Fabric Object Store
  Describes installation of the HPE Ezmeral Data Fabric Object Store software with or without the Installer.
- Installing Kubernetes Interfaces for Data Fabric
  This section describes how to plan for and install the Container Storage Interface (CSI) Storage Plugin and the Kubernetes Interfaces for Data Fabric FlexVolume Driver.
- Upgrading Core or EEP Components
  Depending on your current configuration, you may choose to upgrade the release version (core), ecosystem components, clients, or monitoring components.
- Setting Up Clients and Services
  Describes how to set up and use interfaces to an HPE Ezmeral Data Fabric cluster from a client computer.
- Setting Up the Control System
  Describes how to configure and access the Control System.
- Migrating to the HPE Ezmeral Data Fabric
  Provides instructions for migrating business-critical data and applications from an Apache Hadoop cluster to an HPE Ezmeral Data Fabric cluster.
- Applying a Patch
  You can apply a patch by using the Installer, by using the command line (a manual process), or by using an Installer Stanza.
