10 DELL EMC HPC System for Life Sciences v1.2 | Document ID | version (optional)
Port 10 and 11 are used for the PDUs.
Note: Installation of four SFP+ to RJ45 transceivers in Dell EMC Networking S3048-ON switch ports 49-52 is
required.
2.2.2 High-Speed Interconnects
In high performance computing, application performance depends on the number of CPU/GPU cores, memory,
interconnect, storage performance and so on. For a server to perform better, lower latency and higher
bandwidth is needed for these systems to communicate with each other. The type of network chosen for
computational traffic depends upon the latency, bandwidth, packet size at peak bandwidth and the message
rate. The types of computational network and the switch through which it is offered are tabulated below:
