# Infini Band Partition

InfiniBand (IB) is a high-performance, low-latency networking standard designed for interconnecting servers and storage in HPC (High-Performance Computing) and AI systems,
utilizing RDMA (Remote Direct Memory Access) to reduce CPU overhead. InfiniBand Partitions are used to group Machines into logical partitions for network isolation and load distribution.
