Deploying NetApp Global File Cache

Thank you for your interest in the NetApp Global File Cache (GFC) solution. This page provides a quick start guide for a first-time installation.

Important: Physical keys are not distributed for GFC licensing. GFC licenses are activated in the software UI using subscription number. If you have arrived at this page and have not received a notification via email from NetApp containing subscription number, please contact us at for assistance. If you received a notification via email from NetApp and already have a subscription number. you are ready to complete your initial installation. Please follow the installation instructions below.


Global File Cache Overview

As Global File Cache deploys transparently on a Microsoft Windows Server instance enterprises can consolidate local storage and embed services like Microsoft Active Directory, DNS/ DHCP, DNS, DFS Namespaces, and SCCM software distribution in their unified IT infrastructure. GFC is optimized to work with your existing Azure NetApp Files (ANF), Cloud Volumes ONTAP (CVO), or Cloud Volume Services (CVS) infrastructure.

This guide will show you how to add the building blocks to deploy the Global File Cache Core and Edge instances. We will guide you through the process of deploying the Core Instance in the public cloud and provide you with the instructions to start off your branch office deployment(s), the Edge instance(s).

Important: If you are using Cloud Manager to enable Global File Cache, you should use for a step-by-step walkthrough. 

Cloud Manager automatically provisions the GFC Management Server instance alongside the GFC Core instance and enables entitlement / licensing.

1. Preparations

To prepare for optimal deployment of the NetApp Global File Cache solution, we would like to share the essential solution requirements and potential change requests required.

IMPORTANT: Consult the latest NetApp Global File Cache User Guide for more detail around the solutions' hardware / software, virtualization requirements, integration options along with Global File Cache and end user application best practices (i.e. Autodesk AutoCAD, Autodesk Revit).


To complete a successful installation you must have your customer ID. The customer ID is sent via email after registering for the GFC service. If you have not received your customer ID please stop and contact your NetApp account representative.

The following configuration changes must be completed in the environment before we can start the implementation of the NetApp Global File Cache software.

Implement Firewall Rules

There are several TCP ports used by the NetApp Global File Cache software services. These ports must be excluded from any WAN Optimization devices or Firewall restriction policies for the NetApp Global File Cache software to operate properly.

[Note: Validate that you can reach above urls]

Configure Service Account

The Global File Cache Edge instances will connect to the Core instance to access public cloud file storage resources. The services on this instance run as a specific domain user account. This account, also known as the “Service Account”, must have the following privileges on each of the SMB servers that will be associated with the Core instance:

    • The provisioned Service Account must be an Active Directory Domain User
    • Depending on the level of restrictions and GPOs in the network environment, this account may require domain admin privileges
      • It must have the “Log on as a Service” privileges
      • The password should be set to “Never Expire”
      • The account option “User must change password at next logon” should be DISABLED (unchecked) 


Cloud Volumes ONTAP:

On ONTAP System Manager, in the top bar click "Return to classic version"
  • Navigate to Storage \ Storage VMs
  • Click on the respective Storage VM Name
  • Go to Storage, SVMs, click your SVM, SVM Settings (top right)
    • Scroll down to "Host Users and Groups"
      • Select "Windows"
      • Open "Groups" Tab
        • Select "BUILTIN\Backup Operators" group
        • Click "Edit"
          • In the "Members" section, click add
          • Provide the Active Directory Service Account and add to the group
        • Click "Modify" to commit the changes
Cloud Volumes Service:
  • The Service Account MUST be a member of the Domain Administrators group in the Active Directory (resource) domain where both GFC Core and Cloud Volumes Service resides
Azure NetApp Files:
  • You can include additional accounts that require elevated privileges to the computer account created for use with Azure NetApp Files. The specified accounts will be allowed to change the NTFS permissions at the file or folder level. For example, you can specify a non-privileged service account used for migrating data to an SMB file share in Azure NetApp Files
  • Please consult to enable the “ANFBackupOperator” feature and add the Global File Cache service account to the Azure NetApp Files “Backup Policy Users” list.

Configure Antivirus Exclusions

Antivirus software or other third-party indexing or scanning utilities should never scan drive D:\ on the Global File Cache Edge instance. Scanning the Global File Cache Edge instance server drive D:\ will result in numerous file open requests for the entire cache namespace. This will result in file fetches over the WAN to all file servers. This will cause WAN connection flooding and create unnecessary load on the Edge instance resulting in significant performance degradation.

In addition to the D:\ drive, the following NetApp Global File Cache directories, files and processes should be excluded from all antivirus applications:

  • C:\Program Files\TalonFAST\
  • \Device\TalonCacheFS
  • C:\Program Files\TalonFAST\Bin\LMClientService.exe
  • C:\Program Files\TalonFAST\Bin\LMServerService.exe
  • C:\Program Files\TalonFAST\Bin\Optimus.exe
  • C:\Program Files\TalonFAST\Bin\tafsexport.exe
  • C:\Program Files\TalonFAST\Bin\tafsutils.exe
  • C:\Program Files\TalonFAST\Bin\tapp.exe
  • C:\Program Files\TalonFAST\Bin\TService.exe
  • C:\Program Files\TalonFAST\Bin\tum.exe
  • C:\Windows\System32\drivers\tfast.sys
  • C:\Program Files\TalonFAST\Bin\TappN.exe
  • C:\Program Files\TalonFAST\Bin\FTLSummaryGenerator.exe
  • C:\Program Files\TalonFAST\Bin\RFASTSetupWizard.exe
  • \\?\TafsMtPt:\

PowerShell: Windows Defender Exclusions

The following commands must be executed from PowerShell to enable exclusions for Microsoft Windows Defender:

Write-Host "Adding GFC exclusions to Windows Defender (local)"

Add-MpPreference -ExclusionPath \\?\TafsMtPt:\
Add-MpPreference -ExclusionPath "\Device\TalonCacheFS\"
Add-MpPreference -ExclusionPath "C:\Program Files\TalonFAST\bin\"

Once you have implemented the respective RFC’s, provisioned the core/edge VM instances and joined to your organization's Active Directory Domain, consult the deployment video below to configure the License Management Server, Global File Cache Core and Edge instances.


To enable the Global File Cache License Management Server (LMS), your customer ID will be required. You should have received this email from NetApp’s Global File Cache Support/Operations team.

3. Deploy LMS, GFC Core, Edge

3. Validation Onboarding

This is the final phase of the Global File Cache deployment, the end-user implementation phase.

In order to prepare and streamline the on-boarding of end-users please use the email template linked below that will help you to ‘educate’ the end users on what it means to work in a ‘central data’ environment. This will help your users leverage all of the benefits of the Global File Cache solution. We have also published a video that can be shared to ‘train’ the users where needed.

1. User Training (Generic)
2. User Training (AutoCAD / Revit)

Customize and forward the following resources to the end-users to prepare them for roll-out:
