Minimum Requirements for Sisense in Linux Environments

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.

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).

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

Recommended Deployment Sizes

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.

• Your Linux deployment must use AVX2 (also known as Haswell New Instructions).
• 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:
  • https://data.sisense.com/linux/scripts/sisense_azure_kubespray.sh
  • https://data.sisense.com/linux/scripts/sisense_azure_aks-1.18.sh
• 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:

  Kubernetes Version	1.20	1.21	1.22	1.23	1.24
  Sisense Version

  L2023.3	✓	✓	✓	✓**	✓**

  * Kubernetes 1.22 is only supported for RKE or Provisioner installations.

  ** If installing or upgrading to EKS 1.23 or higher, see Creating a Service Account for the EBS CSI Driver on EKS.

Open Ports Requirements

Linux outbound ports:

• 443
• 80

The following inbound and outbound ports must be open in the server's firewall before the installation. In the table below:

• Same security group means that, for an internal cluster, all of the Kubernetes nodes need to open those ports to any other Kubernetes nodes within the cluster.

• Customer IP Address means that those ports should be accessible from outside the cluster, in order to use the application. The customer can set the IP scope level, that is, who is able to access the network.

Server Connectivity Requirements

The servers must be connected to the Internet and must have network access to the following server list:

• apt.dockerproject.org
• archive.ubuntu.com
• auth.cloud.sisense.com
• bitbucket.org
• bugs.launchpad.net
• dl.fedoraproject.org
• docs.docker.com
• docs.helm.sh
• download.docker.com
• github.com
• gcr.io
• github.com
• grafana.com
• help.ubuntu.com
• index.docker.io
• kubernetes.io
• l.sisense.com
• mirror.centos.org
• ppa.launchpad.net
• pypi.python.org
• quay.io
• registry-1.docker.io
• storage.googleapis.com
• www.ubuntu.com
• yum.dockerproject.org

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

The following whitelisted resources must be added:

• cdn.redhat.com (for details, see https://access.redhat.com/articles/1525183)
• pypi.org to install python modules
