Why Choose This Product?

• One adapter, two networking personalities - VPI lets buyers use the platform for supported InfiniBand or Ethernet deployments, reducing the need for separate adapter families.
• Dual-port 100Gb connectivity - Two QSFP28 ports provide substantial network capacity for servers requiring multiple high-speed links.
• PCIe 4.0 x16 host interface - Provides the appropriate high-bandwidth PCIe connection for demanding 100Gb networking workloads.
• Designed for HPC and data centers - ConnectX-5 Ex combines high-speed networking with RDMA, offload and virtualization capabilities.
• Better CPU efficiency - Hardware offloads for supported network operations can reduce CPU involvement and leave more compute resources available for applications. 
• Storage acceleration capability - RDMA and NVMe-over-Fabrics-related offload features make the adapter relevant to performance-oriented storage environments. 
• Virtualization-ready architecture - SR-IOV and hardware-based I/O virtualization support can help organizations build isolated, scalable virtualized network environments.
• Flexible deployment options - Support for multiple Ethernet speeds and both InfiniBand/Ethernet operation makes the adapter useful across evolving infrastructure requirements.
