The Cisco UCSB-MLOM-40G-03 is a high-performance Virtual Interface Card (VIC) 1340 designed for Cisco UCS blade servers, providing unified high-speed network connectivity for enterprise data center environments.
It is a mezzanine (mLOM) adapter installed directly into Cisco UCS B-Series blade servers, delivering up to 40Gbps connectivity through QSFP+ interfaces. This adapter supports both Ethernet and Fibre Channel over Ethernet (FCoE), allowing LAN and SAN traffic to run over a single converged network fabric.
The module offers flexible connectivity with configurations such as 2x 40Gb ports or 4x 10Gb logical interfaces, enabling scalable deployment based on network requirements. It also supports advanced virtualization features, allowing creation of multiple virtual NICs (vNICs) and HBAs, which is ideal for virtualized and cloud environments.
Built for performance and efficiency, it integrates seamlessly with Cisco’s Unified Computing System (UCS) architecture, reducing infrastructure complexity by consolidating networking and storage traffic. It is commonly used in data centers, virtualization clusters, and high-performance enterprise workloads.
The card is hot-swappable and designed for high availability, ensuring minimal downtime during maintenance or upgrades. It supports fiber connectivity over various cable types including OM3/OM4 multimode and single-mode fiber for flexible deployment distances.
