Windows 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.

Prior and future updates or service packs on these operating systems are supported unless otherwise stated. The operating system version and updates must also be supported by the operating system provider.

Hardware requirements

• Processor: 4 cores for 100 concurrent users
• Memory/RAM: 8 GB
• Disk space: 10 GB

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.

Firewall settings

Portal for ArcGIS communicates on ports 7080, 7443, 7005, 7099, 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 and fully qualified domain name 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, friendly.domain.com instead of portal.domain.com). 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:

• Configure ArcGIS Web Adaptor with your portal.
• Federate an ArcGIS Server site with your portal.
• Add Portal for ArcGIS to your organization's reverse proxy server. If you're not using a reverse proxy server, it's recommended you assign a friendly name to the machine hosting ArcGIS Web Adaptor.

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. You must 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 the ArcGIS Web Adaptor documentation for details.

Supported web browsers

For the best performance in the portal website, use the latest browser versions listed below. 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.

• Internet Explorer 11 (Active scripting must be enabled for the portal website to function correctly.)
• Edge
• Firefox
• Chrome
• Safari
• Android Browser
• Chrome for Android

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

When running third-party applications with ArcGIS Enterprise, 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 Enterprise:

• VMware vSphere 5.5, 6.0, and 6.5
• Microsoft Hyper-V
• Huawei FusionSphere 5.1 and 6.0
