Hardware components of the Dell Validated Design for Analytics — Modern Data Stack system include:
- The Dell PowerEdge R660 server is perfectly matched for compute-intensive workloads while also minimizing the data center footprint through its 1U form factor. The PowerEdge R660 design enables business to easily scale while still handling challenging and emerging workloads. This dual-socket compute platform is ideal for the Red Hat OpenShift control nodes. Control nodes handle the resource allocation, scheduling, system monitoring while maintaining the state of the cluster.
- The worker nodes handle all the
heavy lifting
for the solution. The PowerEdge R660 server model was chosen for this purpose due to its ample performance and flexibility to efficiently handle containerized workloads. This server supports PCIe Gen5 for faster access and transport of data, optimizing application output. Also, this server has enough capacity to support GPUs and I/O bandwidth. - 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 ever-changing network configurations. The software-defined networking enables a communications fabric that can change and adapt to the containerized compute cluster. The fabric optimizes communications paths when the compute demands as workloads are deployed and shifted across the worker nodes.
- The Dell PowerScale H7000 hybrid storage platform delivers a versatile yet simple scale-out storage architecture accessing massive amounts of data. With scalability of up to 1.28 PB per chassis and up to 8 GB/s of data bandwidth, the PowerScale H7000 can support demanding modern data stack environments. The OneFS-powered scalable storage speeds access to massive unstructured data stores that can help feed data-hungry applications and analytics. The PowerScale H7000 achieves up to 80% storage utilization compared with the 50% of traditional storage solutions. It is better suited for the demands of modern data stacks and continually changing underlying compute models.
- Some modern data stacks include workloads that demand both unstructured data storage and object-based storage. The ECS EX500 delivers the perfect blend of economy and density for modern applications or deep archive environments. 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.
