InfiniBand Network Architecture

InfiniBand Advantages

Some of the major advantages offered by the InfiniBand network architecture include the following:

• Supports multiple protocols, including tunneling packets associated with virtually any non-InfiniBand protocol through an InfiniBand fabric.

• Throughput of 2.5Gb/s, 10Gb/s, or 30Gb/s is achievable (depending on the link width implemention).

• Non-privileged applications can send and receive messages without causing a kernel privilege mode switch.

• The processor is not involved in message passing. Rather, each network message transfer is handled by hardware DMA transfer engines within the channel adapter.

• The InfiniBand protocol includes message transfer commands that permit direct memory-to-memory message transfers between the local ...
