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, " below.

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

2-core

8 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.
  • 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.

Note: For Tableau Server 10.3, you need a minimum of 2 physical cores. If you are installing on an Amazon EC2 instance, this means 4 vCPUs. For more information, see Amazon EC2 Instances.

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.

Single node

64-bit

8-core, 2.0 GHz or higher

32 GB

50 GB

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.

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:

\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.

2015-04-09 14:22:29.713 -0700_DEBUG_10.36.2.32:_:_pid=21488_0x2cd83560__user=__request=__ Detected 12 cores and 4 bytes of memory

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
