Lustre and Visual Effects and Finishing applications communicate through Wiretap over a network connection. The network infrastructure can be GigE or InfiniBand. A GigE connection is sufficient for SD and HD 8-bit workflows. An InfiniBand connection is recommended for high-resolution projects like HD 10-bit, 2K, and beyond.
