Abstract--With the emergence of new technologies such as
Virtual Protocol Interconnect (VPI) for the modern data center,
the separation between commodity networking technology and
high-performance interconnects is shrinking. With VPI, a single
network adapter on a data center server can easily be configured
to use one port to interface with Ethernet traffic and another
port to interface with high-bandwidth, low-latency InfiniBand
technology. In this paper, we evaluate ConnectX VPI using
microbenchmarks as well as real traces from a three-tier data
center architecture. We find that with VPI each network segment
in the data center can use the most optimal configuration
