Minimum Hardware Requirements and Recommendations for Tableau Server

Tableau Server on Windows now includes Tableau Services Manager (TSM), which replaces the Configuration Utility and the tabadmin command line tool. If you need help for an earlier version of Tableau Server, see the Tableau Help page.

The following minimum hardware requirements and recommendations apply to all computers running Tableau Server, including physical hardware and virtual machines (VMs):

  • Minimum requirements are the minimum hardware your computer must have in order to install Tableau Server. If your computer does not meet these requirements, the Setup program will not install Tableau Server. These requirements are appropriate for testing and prototyping.

  • Minimum recommendations are higher than minimum requirements, and represent the minimum hardware configuration you should use for a production installation of Tableau Server. If your computer meets the minimum requirements but does not meet these recommendations, the setup program will warn you but you can continue the installation.

In addition, Tableau Server should not be installed on a physical computer or on a VM instance that is also running resource-intensive applications such as databases or application servers.

Note: If you install Tableau Server on a computer that meets the minimum requirements but does not have at least 8 cores and 16 GB of system memory, the default number of all processes installed is reduced to one of each process by design. For more information about processes, see Server Process Limits

Minimum Hardware Requirements

The computer on which you are installing or upgrading Tableau Server must meet the minimum hardware requirements. If the setup program determines that your computer does not meet the following requirements, you will not be able to install Tableau Server.

For more information on how the Setup program determines hardware, see Determining Computer Hardware.

These minimum requirements are appropriate for a computer that you use for prototyping and testing of Tableau Server. They apply to single-node installations and to each computer in a distributed installation.

Minimum Hardware Requirements

64-bit (x64 chipsets)

4-core

16 GB

15 GB

For the requirements:

  • Free disk space is calculated after the Tableau Server Setup program is unzipped. The setup program uses about 1 GB of space. You may need to allocate additional disk space depending on the various factors like whether or not you will be using extracts. For more information, see Disk Space Requirements.

  • Core count is based on "physical" cores. Physical cores can represent actual server hardware or cores on a virtual machine (VM). Hyper-threading is ignored for the purposes of counting cores.

Minimum Hardware Recommendations

For production use, the computer on which you install or upgrade Tableau Server should meet or exceed the minimum hardware recommendations. These recommendations are general. Actual system needs for Tableau Server installations can vary based on many factors, including number of users and the number and size of extracts. If the setup program determines that your computer does not meet the following recommendations, you will get a warning, but you can continue with the setup process. The minimum recommendations listed here is a general guidance. However the recommendations for your environment may vary. For more information, see the Hardware recommendations section of the Recommended Baseline Configurations topic.

32 GB

50 GB

If you are adding Tableau Prep Conductor to your Tableau Server installation, it is recommended to add a second node and dedicate this to running Tableau Server Prep Conductor. This node should have a minimum or 4 cores (8 vCPUs), and 16 GB of RAM.

Multi-node and enterprise deployments

Contact Tableau for technical guidance.

Nodes must meet or exceed the minimum hardware recommendations, except:

  • Nodes running backgrounder, where 4 cores may be acceptable.

  • Dedicated node for Tableau Prep Conductor: Minimum of 4 cores (8 vCPUs), and 16 GB of RAM.

For the recommendations:

  • Free disk space is calculated after the Tableau Server Setup program is unzipped. The setup program uses about 1 GB of space. You may need to allocate additional disk space depending on the various factors like whether or not you will be using extracts. For more information, see Disk Space Requirements.

  • Core count is based on "physical" cores. Physical cores can represent actual server hardware or cores on a virtual machine (VM). Hyper-threading is ignored for the purposes of counting cores.

  • RAM shown is the minimum recommended for a single-node installation. Your installation may function better with more RAM, depending on activity, number of users, and background jobs, for example. For hardware specifications Tableau uses internally for testing scalability, see Hardware Recommendations.

Determining Computer Hardware

To determine how many physical cores a computer has, the Tableau Server setup program queries the operating system. To view hardware information that the setup program detected on your computer, open the tabadmin.log file in the following folder on the computer where you are installing Tableau Server:

<install directory>\ProgramData\Tableau\Tableau Server\logs\tabadmin.log

In the tabadmin.log file, look for lines similar to the following. These lines provide information about the physical and logical cores that the setup program detected and that it used to determine the core count that is being used for licensing.

Manually determining the number of cores on your computer

To determine manually how many physical cores your server has, you can use the Windows Management Instrumentation Command-line tool (WMIC). This is useful if you do not know whether your computer will meet the minimum hardware requirements for installing Tableau Server.

  1. Open a command prompt.

  2. Enter the following command:

    WMIC CPU Get DeviceID,NumberOfCores

    The output will display the device ID or IDs and the number of physical cores the computer has.

    In this example, there are two CPUs, each with six cores, for a total of twelve physical cores. This computer would satisfy the minimum hardware requirements for installing Tableau Server.

    The following command shows a longer version that lists the logical processors as well as the physical cores.

    WMIC CPU Get DeviceID,NumberOfCores,NumberOfLogicalProcessors,SocketDesignation

    In the above example, the server has a total of twelve physical cores, resulting in 24 logical cores.
