Portal for ArcGIS 10.4.x system requirements

The system and hardware requirements required to run Portal for ArcGIS are listed below. For information about earlier versions, see Esri Support.

It's recommended that you review the deprecation notice to determine if your hardware and software components are still compatible with version 10.4.1.

Operating system requirements

The following 64-bit operating systems satisfy the minimum operating system requirements. Support is not provided for 32-bit operating systems; the setup will only proceed if the operating system is 64 bit.

Machines with an underscore (_) in their names are not supported. Several widely used Internet host name specifications have designated the underscore character as nonstandard. Although Windows allows you to use the underscore in a machine name, it can still cause problems when you interact with other servers and platforms. For this reason, Portal for ArcGIS will not proceed with installation on servers that have an underscore in the host name.

Portal for ArcGIS is not supported on domain controllers. Installing Portal for ArcGIS on a domain controller may adversely affect functionality.

*Support begins at ArcGIS 10.4.1


Windows 10, 8.1, 8, and 7 are supported for basic testing and application development use only. They are not recommended for deployment in a production environment.

Hardware requirements

  • Processor: 4 cores for 100 concurrent users
  • Memory/RAM: 4 GB or more
  • Disk space: A base installation of Portal for ArcGIS requires a minimum of 3.2 GB of available disk space. All content created by your users will also be stored on disk. Carefully consider how data will be uploaded and created by your users and allocate disk space accordingly. If desired, you can change the location of where the portal stores its content after installing the software.

Disk space requirements

Portal for ArcGIS requires a minimum of 3.2 GB of available disk space.

Firewall settings

Portal for ArcGIS communicates on ports 7080, 7443, 7005, 7099, 7199, and 7654. You'll need to open these ports on your firewall before installing the software. For more information, see Ports used by Portal for ArcGIS.

Domain name service (DNS) and fully qualified domain name (FQDN) requirements

Your organization's domain name service (DNS) needs to include an entry of the fully qualified domain name (FQDN) of the machine hosting Portal for ArcGIS. Similarly, if you'll be using ArcGIS Server with your portal, it's recommended that you include FQDN entries for each site you intend to federate with Portal for ArcGIS.

If desired, you can configure your DNS to use a friendly name for the portal (for example, instead of When doing this, assign the name to the portal machine before you install the software. Then use the friendly name when setting up the portal. For example, setup activities that require use of the friendly name include the following:


If you configure a friendly DNS name after setting up your portal, existing items in the portal may become unusable, as they will include the nonfriendly name. You'll need to manually re-create each item in order to use them again.

SSL certificates

Portal for ArcGIS comes preconfigured with a self-signed server certificate, which allows the portal to be initially tested and to help you quickly verify that your installation was successful. However, in almost all cases, an organization should request a certificate from a trusted certificate authority (CA) and configure the portal to use it. The certificate can be signed by a corporate (internal) or commercial CA.

You should configure each applicable ArcGIS component in your organization with a certificate from a corporate or commercial CA. Common examples include ArcGIS Web Adaptor and ArcGIS Server. For example, ArcGIS Server also comes with a preconfigured self-signed certificate. If you'll be federating an ArcGIS Server site with your portal, it's very important that you request a CA-signed certificate and configure the server and Web Adaptor to use it.

For more information, see Security best practices.

ArcGIS Web Adaptor

ArcGIS Web Adaptor is a required component of Portal for ArcGIS, which allows you to integrate your portal with your existing web server and your organization's security mechanisms. You cannot deploy Portal for ArcGIS in your organization without the Web Adaptor.

You can only use the Web Adaptor with port 80 or 443. Using different ports is not supported. See About ArcGIS Web Adaptor for details.

Supported web browsers

For the best performance in the portal website, use the latest browser versions listed below. The scene viewer has its own browser and hardware requirements. Some of the common clients of Portal for ArcGIS have different requirements. See their documentation for details.

  • Microsoft Internet Explorer 9 and higher. Compatibility View is not supported.
  • Microsoft Edge
  • Mozilla Firefox (version 10 or later)
  • Google Chrome (version 10 or later)
  • Safari
  • iOS Safari
  • Android Browser
  • Chrome for Android

Browser limitations

Some web browsers have functional limitations, as noted below:

  • You cannot add CSV items (in My Content) as web layers in the map. This limitation applies to IE 9 and Safari.
  • You cannot use the scene viewer. This limitation applies to IE 9 and 10.
  • You cannot view streaming feature layers in the map viewer. This limitation applies to IE 9.
  • The X-Frame Options ALLOW-FROM header is not supported in Chrome and Safari. When viewing the portal website, you may encounter an error in Chrome and Safari stating that the header is invalid and will be ignored. You can safely dismiss this warning.

If your organization is unable to turn off Internet Explorer Compatibility View, please see this tech article for a workaround:

External access

If you'll be using Esri-provided services, such as basemaps and data from ArcGIS Online, the machine hosting Portal for ArcGIS will need access to the Internet. If your portal will not have access to the Internet, you'll need to perform some additional configuration steps to ensure your portal is pointing to local resources. For instructions, see Configuring a disconnected deployment.

Supported virtualization environments

All components of ArcGIS for Server are fully supported on virtual environments as long as they run on supported platforms. When running third-party applications with ArcGIS for Server, such as relational databases, the application must also be supported in a virtual environment. Check the third-party vendor for its virtualization support.

The following virtualization environments are known to perform well with ArcGIS for Server:

  • VMware vSphere 5 including 5.0, 5.1, and 5.5
  • VMware vSphere 6
  • Microsoft Hyper-V
