Please clarify Classic Storage and Service requirement for HPC

It seems like though the infrastructure provisioned in ARM mode Azure cloud service and an Azure storage account must be configured in classic to build a HPC cluster (Not talking about batch).

While configuring HPC manager for node template it will not work until unless one has a classic storage account.
Is there a way to use ARM storage account?

Thanks

Review the issue's Azure HPC Manager node-template setup and the stated distinction between classic and ARM storage accounts. Determine whether ARM storage is supported or document the required classic resources; the issue provides no files or tests to start from.
