Gigabit has never been more affordable. Every Pinnacle Server comes standard with at least 1Gb adapter onboard. Today most switches are wire speed to every port, and many support jumbo frames. Switch configurations come in every size, from 4 ports to hundreds. Switches up to 48 ports are extremely affordable and most have uplinks that allow them to expand for additional nodes. To help conserve rack space, switches 48 ports and less come in a convenient 1U form factor.
Depending on your job, gigabit may be the perfect solution. With a standard gigabit switch, you can expect 1Gb/sec bi-directionally and 30µs latency. If you require high bandwidth or low latency, a high-speed interconnect might be a better solution for your cluster. Ask us about testing your code using one of our Apex HPC clusters. We have most interconnects on hand for you to test to help you find the best solution for your particular code.
With the growing deployment of multiple, multi-core processors in server and storage systems, overall platform efficiency and CPU and memory utilization depend increasingly on interconnect bandwidth and latency. For optimal performance, platforms with several multi-core processors can require interconnect bandwidth of more than 10Gb/s or even 20Gb/s.
