Figure 4 provides an overview of the physical architecture that was used in this validation.
Control plane nodes run the components that are responsible for managing the OpenShift cluster. We used three Dell PowerEdge R7615 Servers as control plane nodes.
Dell PowerEdge R7615 Server is a single socket rack-based server model and powered by AMD EPYC 9124 processor with 16 physical cores. Dell PowerEdge R7615 is designed to be the most economical investment per dollar for the data center and provides better price performance ratio and flexible low-latency storage options. Target workloads include software-defined storage (SDS), virtualization, data analytics.
Worker nodes run the pods that contain the application and provides compute and storage resources to the applications. We used seven Dell PowerEdge R7625 Servers as worker nodes. Storage of four worker nodes is dedicated for the ObjectScale instance and three worker nodes are dedicated for RHODF.
These worker nodes have enough CPU and memory to handle the compute resources required for SQL analytic workloads. They also provide capacity for both persistent block storage (RHODF) and object storage (Dell ObjectScale).
Dell PowerEdge R7625 is a dual-socket server model and powered by AMD EPYC 9334 processor with 32 physical cores, provides breakthrough performance. Dell PowerEdge R7625 is designed to be the backbone of the data center. These extremely powerful servers provide ample performance and flexible low-latency storage options. Target workloads include High Performance Computing (HPC), Virtual Desktop Infrastructure (VDI), virtualization, and data analytics.
We used two Dell PowerSwitch S5248F-ON top of the rack (ToR) switches for the data path. The Dell PowerSwitch S5248F-ON provides state-of-the-art, high-density 25 GbE ports and a broad range of functionality to meet the growing demands of today’s data center environment. These switches offer flexible options for changing network configurations and adapt to the deployment in a containerized environment. Additionally, we have used two 1GbE/10 GbE management switches for out-of-band connectivity.
These nodes hosts VMs which run client applications and tools required to manage the Red Hat OpenShift cluster, ObjectScale, Apache Spark and SQL Server. Also, infra VMs host different services such as AD, DNS, NTP.
