Dell EMC recommends a 25 Gb network infrastructure to support the Domino Data Science Platform. A productive data science team can tax the network by copying large amounts of data and, sometimes, performing distributed training with CPU- or GPU-based experiments.

The following Dell EMC switches are typically used in building an environment to power Domino Data Science Platform:

• Dell Networking S5224 or S5248 Top of Rack Switch—The S5200 series of switches come in 12, 24, 48, and 96 25 Gb port configurations with additional 100 Gb ports for uplink to spine switches. The S5248 ToR switch runs the latest OS10 operating system and supports RDMA, which can provide faster access to data and accelerate distributed training with NVIDIA GPUDirect technologies. The S5200 series of switches can also be used in End of Row (EoR) and Middle of Row (MoR) deployments to increase density.
• Dell Networking Z9100 Spine Switch—The Z9100 switch can be configured with 32 nonblocking 100 Gb ports and the latest OS10 operating system to act as a spine switch. The Z9264 switch supports 64 nonblocking 100 Gb ports.
