Minimum Requirements for Sisense in Linux Environments

  • Dark
    Light

Below are descriptions and explanations describing the minimum requirements for Sisense in Linux environments.

Supported Browsers

The Sisense Web Application runs in the following HTML5 supported browsers:

  • Microsoft Edge
  • Google Chrome
  • Firefox
  • Safari version 7 and higher
    Sisense supports Safari 10 and higher when embedding iFrames.
Note:

Internet Explorer 11
If you are using Internet Explorer 11, Sisense recommends moving to another browser. Microsoft ended IE11 support for various Microsoft products during 2021 and Sisense stopped supporting IE11 by the end of 2021.
IE11 is not supported for the Sisense internal web-based file browser application.

The Sisense Web Application also works in mobile phone and tablet browsers that support HTML5. See Viewing Dashboards on Mobile Devices to learn more about mobile compatibility.

Minimum System Requirements

The Sisense Linux deployment is certified to run on the following operating systems.

Note the following:

  • Sisense supports only x86-64/AMD64 architecture (e.g., ARM64 currently not supported). You can verify this by running the "hostnamectl" command in Linux to confirm the current architecture in place (e.g., Architecture: x86-64).
  • The OS versions specified below are also based on the minor release number, and should be taken into consideration to ensure proper compatibility (e.g., CentOS 8.4 is not currently supported as it is not specified below).
  • The OS needs to be an official release of the given Linux OS, and one that has not been customized (e.g., where the OS was modified to harden the kernel).

Note:

The CentOS Project set December 31, 2021, as the CentOS 8 end-of-life date, and no operating system updates will be issued after that date. Sisense will align with the CentOS 8 EOL date.
For continued support, Sisense customers must migrate to a supported OS version, such as CentOS 8 Stream (supported by Sisense Linux v2021.9), CentOS 7, or another supported OS version that is listed in the table.

Minimum Hardware Requirements

Ensure that your system has at least the following hardware requirements:

  • 8 CPUs
  • The memory requirements specified in the recommended deployment sizes table

The table below describes the minimum requirements for your production deployment. The exact deployment parameters depend on your specific use-case and usage needs.

It is possible for a deployment with machines that have more memory and cores to exceed the large-scale recommendations.

Deployment SizeSmall ScaleMedium ScaleLarge Scale

Deployment type

Single node, cluster optional

Recommended: Cluster

Disk IOPS

The disk must have at least:

  • 100MB/s
  • 1600 IOPS

The build nodes disk must have at least:

  • 100MB/s
  • 1600 IOPS

256GB - 512GB

Note:

If the OS defines sub disks for different directories, the following directories must have at least this amount of storage:

  • 300GB for /var/lib
  • 50GB for /var/log/sisense
If more specific sub disks are defined (for example: “/var/lib/docker” and/or “/var/lib/kublet”), make sure you allocate enough space for each of them, otherwise certain components of the platform will not work.
  • Your Linux deployment must use AVX2 (also known as Haswell New Instructions).
  • The kernel version is held due to the limitation with GlusterFS Fuse.
  • For cluster deployments that use a shared storage, the following requirements are for the cluster’s first three nodes. Each of the first three nodes must have a second unformatted, unmounted, and unpartitioned hard disk with at least 400GB disk space available, plus additional storage for the ElastiCubes.
  • For Azure systems that have a 30GB default capacity, you must stop the instance and expand the OS disk capacity up to 300GB before proceeding with installation. Sisense supplies the following scripts to assist you with expanding the disk capacity:
  • NVMe disks are recommended for the second disk.
    If NVMe disks are not used in your system, SSDs are mandatory.
    Sisense does not support systems running with HDD.
  • AWS disk IOPS is determined by a formula.
    EBS gets 250MB/s at 3000 IOPS at the peak, but tokens are provided depending on the disk size.
  • Servers must be connected to the internet and must have network access to a Docker Hub.
    If you are performing an offline installation, see Installing Sisense in an Offline Environment.
  • The network between the servers must reach at least 1 Gbps.
  • The installation requires the user/password or SSH key. In a multi-node deployment, the same user credentials (password/SSH key) must be defined on all of the server nodes.
  • See Integrating Sisense with Portworx if your environment uses the Portworx platform for end-to-end storage and data management solution on the Kubernetes cluster.
  • Set kubernetes_minimum_pods to 58 per node.

    Compatibility Matrix

  • Kubernetes types supported (for pre-built Kubernetes clusters):
    • AWS Elastic Kubernetes Service
    • Google Cloud Engine
    • Azure Kubernetes Service
    • RedHat OpenShift
  • Sisense on Linux supports Kubernetes versions 1.20 through 1.24, based on the following table:

    • Default Packages Repository
    • Default Packages Repository
    • Default Packages Repository



    Before installing Sisense, ensure that the default packages repository for your Linux distribution is configured and enabled. Sisense installer requires this as it installs the following packages:

    • python 3
    • python3-pip
    • nc
    • sshpass
    • jq
    • libselinux-python3
    • dbus (for Ubuntu only)
    • For RHEL/Centos Linux, access to dl.fedoraproject.org and all its mirrors (cdn.redhat.com network - details are here: https://access.redhat.com/articles/1525183) is required to successfully install all the above packages.
    Check that the packages repository is pre-installed on your server as follows:

    Verification commands (for RHEL/Centos):

    sudo yum install gawk
    sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
    sudo yum install --enablerepo="epel" python3-pip nc sshpass jq libselinux-python3
    
    

    Verification commands for Amazon linux:

    sudo amazon-linux-extras install epel
    sudo yum reinstall python3 python3-pip || sudo yum install -y python3 python3-pip
    sudo yum install nc sshpass jq libselinux-python3
    

    Verification commands for Ubuntu:

    sudo apt-get update
    sudo apt-get install python3 netcat sshpass python3-apt python3-pip dbus
    sudo apt-get install jq
    

    python3 and pip

    python3 and pip must be accessible from terminal via the commands:

    python3
    pip
    

    Verification commands:

    sudo python3 -m pip install --upgrade --force-reinstall pip
    sudo python3 -m pip install configparser zipp
    sudo python3 -m pip install -r kubespray/requirements.txt --ignore-installed (from the installation folder)
    

    The DNS must be configured

    The DNS must be configured in the system. This is needed to resolve:

    • the Docker registry
    • The DNS server must be accessible from the Kubernetes nodes where Sisense is deployed, for Sisense component interconnections to function properly.
    • Whitelisted Resources
    • Whitelisted Resources



    The following whitelisted resources must be added:
