The responsibility of configuring a customer's DAS will fall solely on the service delivery support team assigned to the account. Infrastructure's responsibility will be to ensure that the array controller can see the disks and are installed properly.

Below is an example of configuring a DAS array attached to a BOBJ/SAP server. Please feel free to update or change this page if you are able to provide a more relevant example.
