InfiniBand will reach 200-gigabit speed next year

InfiniBand is set to hit 200Gbps in products that were announced Thursday, potentially accelerating machine-learning platforms as well as high-performance computing systems.

The massive computing performance of new servers equipped with GPUs calls for high network speeds, and these systems are quickly being deployed to handle machine-learning tasks, Dell’Oro Group analyst Sameh Boujelbene said.

So-called HDR InfiniBand, which will be generally available next year in three sets of products from Mellanox Technologies, will double the top speed of InfiniBand. It will also have twice the top speed of Ethernet.

But the high-performance crowd that’s likely to adopt this new interconnect is a small one, Boujelbene said. Look for the top 10 percent of InfiniBand users, who already use 100Gbps InfiniBand, to jump on the new stuff, she said.
