This solution includes the following components from the Dell Validated Design for Data Analytics – Data Lakehouse, which draws on the strength of multiple Dell platforms. These platforms have been carefully chosen for their ability to handle compute-intensive workloads and scale to the demanding needs of data lakehouse environments.
The Dell PowerEdge R650 server is perfectly matched for compute-intensive workloads while also minimizing the data center footprint through it 1U form factor. The PowerEdge R650 design enables business to easily scale while still handling challenging and emerging workloads. This dual-socket compute platform is perfectly matched to the management and control needs for the solution’s control nodes. Control nodes handle the resource allocation, scheduling, system monitoring while maintaining state across the cluster.
The worker nodes handle all the “heavy lifting” for the solution. The choice of the Dell PowerEdge R750 server easily handles the containerized environment, with the ability to change based on the workload demands and compute needs. The full featured enterprise server features a flexible 2U enclosure which provides the additional room for adding I/O bandwidth and storage capacity. Extensive GPU and storage support bring the ultimate in flexibility for workloads.
The Dell PowerSwitch S5248F-ON delivers the top of rack switching. It is a 25 GbE/100 GbE open networking switch that provides state-of-the-art, high-density switching. The open networking capability provides extra flexibility for changing network configurations as the clustered workloads scales. The software defined networking enables a communications fabric that can change and adapt to the containerized compute cluster. The fabric optimizes communications paths with the compute demands as workloads are deployed and shift across the worker nodes.
The Dell ECS EX500 delivers the perfect blend of economy and density for modern applications or deep archive environments and is used in this design for Splunk SmartStore. With scalability of up to 16 nodes, the ECS EX500 can handle up to 6,144 TB of unstructured storage per rack. Dell ECS enables enterprise-grade cloud scale storage for unstructured (object and file) storage while maintaining control, in a private cloud environment. The software-defined storage is layered to help enable a limitless scalability while maintaining the abstraction that promotes high availability.
The solution architecture, components and their recommended configurations, implementation best practices, and several validated use cases for predictive maintenance are all described in greater detail in the design guide.
