Did you know?

Virtual Protocol Interconnect (VPI) enables standard networking, clustering, storage, and management protocols to seamlessly operate over any converged network by leveraging a consolidated software stack. Each port can operate on InfiniBand, Ethernet, or Data Center Bridging (DCB) fabrics, and supports Ethernet over InfiniBand (EoIB) as well as RDMA over Converged Ethernet (RoCE). VPI simplifies I/O system design and makes it easier for IT managers to deploy infrastructure that meets the challenges of a dynamic data center.
