Gateway and domains setup

[CSun]

I am working on Azure AS Tabular Model which is in domain X. My datasource is on-prem in domain X.  I am working from domain Y and the gateway is setup in domain y. 

I couldn't find much documentation around cross-domain setup for the gateway. So here are my questions:

1. Is this right\reccomended setup? If not what is the reccommended setup?

2. Are there any documentations around this?

With my setup, when i deploy my tabular model to the Azure AS  i encounter the below errors:

I get this error when I can deploy my metadata but processing fails:

[DM.GatewayCore] ServiceEndpoint Connection status: Connecting, LastError: 'System.ServiceModel.CommunicationException: The connection was inactive for more than the allowed 240000 milliseconds and is closed by container '2cfbf48f3a584793b672affba704b4dd_G53'. ---> Microsoft.ServiceBus.Messaging.Amqp.AmqpException: The connection was inactive for more than the allowed 240000 milliseconds and is closed by container '2cfbf48f3a584793b672affba704b4dd_G53'.
   --- End of inner exception stack trace ---'

I get this error when i can deploy, processing starts and retrieves about 2.1 million rows, and then stays like that for some time and fails:

[DM.Pipeline.Diagnostics] Exception object created [IsBenign=True]: Microsoft.PowerBI.DataMovement.Pipeline.Diagnostics.CancellationException: Task is timeouted with System.Threading.Tasks.TaskCanceledException: A task was canceled.

DM.EnterpriseGateway Information

Any help would be appreciated.

Hi @CSun,

If the Analysis Services server is in a different domain than the data gateway and there is not a two-way trust established. Then you will not be able to use the data gateway to connect this SSAS server. In your scenario, you will need to work with your domain administrators to verify the trust relationship between domains. See: On-Premises Data Gateway FAQ.

Can I install the gateway in the same server where my backend sql server (domain x) is residing?

Hi @CSun,

Of course. You can install the on-premise data gateway on the same machine which has the SQL server runs, as long as the server host data gateway can access the SSAS.  You can follow this article to install data gateway.
