Mellanox ConnectX-4 Adapters
Product Guide
ConnectX-4 from Mellanox is a family of high-performance and low-latency Ethernet and InfiniBand
adapters. The ConnectX-4 Lx EN adapters are available in 40 Gb and 25 Gb Ethernet speeds and the
ConnectX-4 Virtual Protocol Interconnect (VPI) adapters support either InfiniBand or Ethernet.
These adapters address virtualized infrastructure challenges, delivering best-in-class performance to various
demanding markets and applications. Providing true hardware-based I/O isolation with unmatched
scalability and efficiency, achieving the most cost-effective and flexible solution for Web 2.0, Cloud, data
analytics, database, and storage platforms.

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.
