The newest version of IBTA Specification Volume 1 also features support for higher bandwidth NDR InfiniBand and minimum bandwidth setting capabilities via the Enhanced Port Arbiter.
Here’s a rundown of the key features of Release 1.5 from InfiniBand Trade Association:
- Memory Placement Extensions enable hardware OEMs and software developers to implement the MPE operations RDMA Flush and RDMA Atomic Write to enhance PMEM performance and reduce overall latency by a factor of 10.
- InfiniBand now supports NDR, which allows 400 Gbps speeds on a 4-lane port configuration.
- It also supports 2x lanes for much greater port density while still supporting 200 Gbps on these ports.
- Quality of Service has been enhanced via an updated VL Arbitration mechanism which allows a user to specify minimum bandwidth on physical ports and the ability to control virtualized port arbitration by setting rate liming and bandwidth sharing.
