The InfiniBand Specification defines amanagement infrastructure that is the foundation for achieving multi-vendor interoperability in InfiniBand networks.This paper mainly depicts the management model and fundamental concepts of IBA,subnet management state ma-chine, format and usage of the Management Datagram.展开更多
