The PowerScale OneFS scale-out network-attached storage (NAS) platform provides CDP clients with direct access to big data through a Hadoop Distributed File System (HDFS) protocol interface. A PowerScale cluster powered by the OneFS distributed file system delivers a scalable pool of storage with a global namespace.
CDP compute clients can access the data that is stored on a PowerScale OneFS cluster by connecting to any node over the HDFS protocol. All nodes that are configured for HDFS provide NameNode and DataNode functionality. Each node boosts performance and expands the cluster capacity. For Big Data analytics, the PowerScale scale-out distributed architecture minimizes bottlenecks, rapidly serves big data, and optimizes performance for Big Data processing jobs.
CDP Private Cloud Data Services is an on-premises offering of CDP that brings many of the benefits of the public cloud to your data center. It is the framework on top of CDP Private Cloud Base that lets you deploy and use the collection of Cloudera data services such as Cloudera Data Warehouse (CDW), Cloudera Machine Learning (CML), and Cloudera Data Engineering (CDE). These data services can cater to your data-lifecycle goals.
In the below figure, the Cloudera distribution is stored on a separate compute cluster, and individual clients connect directly to the PowerScale OneFS cluster to store and access data. OneFS handles HDFS file-data exchange as a protocol to store and retrieve the data to match the client's requirements.
