Although VectorH aims to keep the inter-node communication to a minimum, there will always be a moderate amount of it. As network bandwidth is relatively low compared to direct memory bandwidth, a high-speed network is highly recommended.
For proper operation, we recommend at least a 10GigE network. 20GigE (2 x 10GigE bonded) or InfiniBand will improve performance. A combination of 10GigE or 20GigE and InfiniBand is also possible. In this case, the system can be configured such that HDFS and other Hadoop components communicate over the 10GigE or 20GigE link and VectorH exclusively communicates over the InfiniBand link.
