Advanced Management Capabilities

Mellanox's switch family enables efficient computing with features such as static routing, adaptive routing, and advanced congestion management. These features ensure the maximum effective fabric bandwidth by eliminating congestion hot spots. Whether used for parallel computation or as a converged fabric, Mellanox switches have the industry's best traffic-carrying capacity.

All Mellanox switches can also be coupled with Mellanox's Unified Fabric Manager (UFM™) software for managing scale-out InfiniBand computing environments. UFM enables data center operators to efficiently provision, monitor and operate the modern data center fabric. UFM boosts application performance and ensures that the fabric is up and running at all times. UFM can also enhance MLNX-OS with UFM Diag diagnostic tools to check node-node, node-switch connectivity and cluster topology view.

Virtual Protocol Interconnect® (VPI)

VPI flexibility enables any standard networking, clustering, storage, and management protocol to seamlessly operate over any converged network leveraging a consolidated software stack. Each port can operate on InfiniBand, Ethernet, Data Center Bridging (DCB) fabrics and 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.
