what are the storage services for azure HDInsight?

It is a general-purpose storage system connected to compute nodes. By storing the data in Azure Storage one has the benefits of data sharing, data achieving, geo-replication and elastic scaling capabilities.These enable data recovery and redundancy.The scale-out file system automatically scaled depending upon a number of nodes connected to the cluster.  Every time when a cluster is generated, there is no need to reload the data. Even after the original HDInsight cluster is deleted, you can still use the default storage container.
