The CISCO UCSC-MLOM-C40Q-03 features the Cisco Virtual Interface Card (VIC) 1387, a dual-port 40Gb QSFP Converged Network Adapter (CNA) designed as a modular LAN-on-Motherboard (mLOM) card. This card is engineered for high-bandwidth, low-latency networking, boasting up to 80 Gbps total bandwidth across two ports. It's optimized for virtualized environments and convergence, supporting direct-attach storage, NAS, and SAN, enabling a unified fabric to reduce cabling and complexity. The VIC 1387 utilizes Cisco's unique virtual interface technology that provides the ability to dynamically allocate bandwidth and fabric connections, adjusting easily to changing workload demands without physical reconfiguration. It's specifically tailored for Cisco Unified Computing System (UCS) servers, enhancing their capabilities to meet the performance and scalability needs of modern data centers, including cloud computing, big data analytics, and application hosting.
