ECS in DD Cloud Tier as a Cloud Unit

In order to integrate ECS in DD Cloud Tier as a Cloud Unit . DELLEMC Guide mentions below requirements from ECS Appliance.

The provider Access key and Secret key.

The provider endpoint IP/hostname

To create a cloud unit for EMC Elastic Cloud Storage:

Navigate to Data Management > File System > Cloud Units.

Click Add.

In the Add Cloud Unit screen, enter a name for the cloud unit.

For Cloud provider, select EMC Elastic Cloud Storage (ECS).

Supply the provider Access key and Secret key.

Enter the provider endpoint with this format: http:// : . If using a secure endpoint, use HTTPS instead.

If an HTTP proxy server is required to get around a firewall, click Configure for HTTP Proxy Server.

Click Add.

I'm curious to know what the  endpoint IP/hostname of provider from ECS is ,  is this the management IP or data IP?

Also if anyone can share some info on how what the provider Access key and Secret key / how do we create it on a ECS that is needed for DD Cloud unit creation .
