Data Center Infrastructure

What is one advantage of InfiniBand compared with Ethernet?

  • A InfiniBand always provides higher bandwidth than Ethernet.
  • B InfiniBand supports RDMA while Ethernet does not.
  • C InfiniBand offers lower latency than Ethernet.
Explanation

InfiniBand is a high-speed, low-latency interconnect designed for efficient data-center and HPC communication. Ethernet can also support RDMA through RoCE, and bandwidth depends on the particular network technologies and generations rather than being inherently higher for InfiniBand.
