Application Networking; 40 Gbit/s and Beyond

Ronald van der Pol (SARA Computing and Networking Services)

SARA’s performance and scalability measurements show that a modern off the shelf server is capable of transmitting 39.5 Gbit/s to the network. Disk I/O measurements showed linear speedup with 6 solid state disks up to around 1400 MiByte/s. Based on these results and the architecture analysis we expect that 40 Gbit/s of sustained read speed is probably possible with more disks. This means that a single application is capable of sending 40 Gbit/s of traffic on a modern server. Previously, clusters and grid setups were needed to reach these application speeds. This opens new exciting possibilities for demanding applications. The latest results of our performance measurements will be shown on the poster.
