Learn how to install a ThoughtSpot cluster in a VMware environment.
Estimated reading time: 3 minutes

This page explains how to install a ThoughtSpot cluster in a VMware VSphere Hypervisor (ESXi) 6.5 environment. For each hardware node, you must:

  • Complete the prerequisites
  • Use the ThoughtSpot Open Virtualization Format (OVF) file to create a virtual machine (VM)
  • Add hard disks to the VM

Prerequisites

This installation process assumes you have already acquired your host machines. You can install on a cluster with any number of nodes. A one node cluster is suitable for a sandbox environment but is insufficient for a production environment. You need at least three nodes for high availability (HA), but there is no limit on the number of nodes.

  1. Make sure you have installed the Hypervisor on each of your three nodes.

    The VM template, by default, captures a 72-core configuration. If your physical host has more than 72 cores, you may want to edit the VM to have (n-2) cores (for a physical host with n cores) to fully take advantage of computing power of the physical host.

  2. Create datastores for all solid-state drive (SSD) and hard drive devices.

Use the OVF to Create a VM

  1. Download the ThoughtSpot OVF from the Downloads page here to a location on an accessible disk.

  2. Log into the ESXi web portal.

  3. Select Virtual Machines > Create/Register VM.

    The system displays the dialog for selecting an OVF template.

  4. Choose the OVF template and press Next.

    The system prompts you to select a storage.

  5. Choose the SSD as the destination and press Next.

    The system displays the Deployment Options dialog.

  6. Enter the options and press Next.

    Setting Value
    Network mappings Select the correct network for your installation.
    Disk provisioning Choose Thin.
    Power on automatically Check this box.
  7. Review your selection and press Finish.

  8. Wait for the template to be loaded.

    Depending on your network speed, loading can take several minutes.

  9. Make sure that VM is powered off.

Add hard disks to the VM

Use Case HDFS Disk Requirements
POC 2 x 1 TB on HDD
Production 3 x 2 TB on HDD

For a proof of concept (POC), follow these steps to create two 1TB HDFS disks on HDD storage, as shown here (2 x 1TB).

For production deployments, ThoughtSpot requires you to have three 2TB HDFS disks on HDD (3 x 2TB). For this use case, follow these same steps to create the additional, larger capacity disks.

  1. Edit the VM you just created.

  2. Select Add hard disk > New hard disk.

    You can give the VM up to 38 cores (or approximately 490 G RAM). The ESXi host should keep a minimum of 2 cores.

    The new disk appears as a new row under the only existing SSD row.

  3. Click the New Hard disk to expand the detailed configuration options.
  4. For a proof of concept, set the options as follows. (For production deployments, set the size to 2TB.)

    Setting Value
    size 1 TB
    Location Use the Browse button to select the hard disk store.
    Thin provisioned Check this box.

    You should see something similar to the following:

  5. Save your changes.
  6. Repeat steps 1-5 to create more hard disks.
  7. Power on the VM
  8. Once the VM is online, run the following command to prepare the HDFS disks:

     sudo /usr/local/scaligent/bin/prepare_disks.sh

There is no network at this point on your VMs. To make the VM node accessible from any terminal within local network, contact [email protected].
