Designed for demanding HPC, cloud, and big data environments, it accelerates virtualization and GPU communication while supporting massive scalability with guaranteed bandwidth and end-to-end data protection. ## Description Connect-ib adapter cards provide the highest performing and most scalable interconnect solution for server and storage systems. High- performance computing, web 2.0, cloud, big data, financial services, performance improvements resulting in reduced completion time and lower cost per operation. Connect-ib delivers leading performance with maximum bandwidth, low latency, and computing storage applications. Maximum bandwidth is delivered across PCI Express 3.0 X16 and two 100 GB/s of throughput together with consistent low latency across all CPU cores. Connect-ib also enables PCI Express 2.0 X16 systems to take full advantage of fdr, delivering at least twice the bandwidth of existing PCIe 2.0 solutions. Connect-ib supports data operations including noncontiguous memory transfers which eliminate unnecessary data copy operations and CPU overhead. Additional application acceleration is achieved with a 4X improvement in message rate compared with previous the next level of scalability and performance requires the data and application accelerations. Mellanox messaging (mxm) and Fabric collective accelerator (fca) utilizing core-direct technology accelerates mpi and pgas communication performance, taking full advantage of connect-ib enhanced capabilities. Furthermore, connect-ib introduces an innovative transport service dynamic transport, to ensure unlimited scalability for clustering of servers and storage systems. ## Features - World-class cluster, network, and storage performance - I/O consolidation - Virtualization acceleration - Scales to tens-of-thousands of nodes - Guaranteed bandwidth and low-latency services - 1 us MPI ping latency - GPU communication acceleration - End-to-end internal data protection ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00I3PNPQA | | Best Sellers Rank | #2,894 in Internal Computer Networking Cards | | Brand | Mellanox | | Built-In Media | Host bus adapter | | Compatible Devices | Personal Computer | | Global Trade Identification Number | 07290107197045 | | Hardware Interface | PCIE x 16 | | Item Type Name | Mellanox MCB194A-FCAT Connect-Ib, Host Bus Adapter, 2 Ports, PCI Express 3.0 X16 | | Item Weight | 8.8 ounces | | Manufacturer | Mellanox | | Mfr Part Number | MCB194A-FCAT | | Model Number | MCB194A-FCAT | | Operating System | PC | | Style | Classic | | Style Name | Classic | ## Images ![Mellanox MCB194A-FCAT Connect-Ib, Host Bus Adapter, 2 Ports, PCI Express 3.0 X16 - Image 1](https://m.media-amazon.com/images/I/71GMcsHj7wL.jpg) ![Mellanox MCB194A-FCAT Connect-Ib, Host Bus Adapter, 2 Ports, PCI Express 3.0 X16 - Image 2](https://m.media-amazon.com/images/I/712wATyZBML.jpg) ![Mellanox MCB194A-FCAT Connect-Ib, Host Bus Adapter, 2 Ports, PCI Express 3.0 X16 - Image 3](https://m.media-amazon.com/images/I/61t-YZziXOL.jpg) ![Mellanox MCB194A-FCAT Connect-Ib, Host Bus Adapter, 2 Ports, PCI Express 3.0 X16 - Image 4](https://m.media-amazon.com/images/I/618CGXUwBgL.jpg) ![Mellanox MCB194A-FCAT Connect-Ib, Host Bus Adapter, 2 Ports, PCI Express 3.0 X16 - Image 5](https://m.media-amazon.com/images/I/71etW1lrfRL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/34992571-mellanox-mcb194a-fcat-connect-ib-host-bus-adapter-2-ports](https://www.desertcart.co.za/products/34992571-mellanox-mcb194a-fcat-connect-ib-host-bus-adapter-2-ports) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-11-06*
