Cisco QLogic QLE2742-CSC Dual-port Gen 6 Fibre Channel Adapter

The Cisco QLogic QLE2742-CSC is a high-performance, dual-port Gen 6 Fibre Channel Host Bus Adapter designed for today’s data centers that demand scalable, low-latency SAN connectivity with minimal impact on server CPU resources. Built to handle mission-critical workloads, this adapter delivers native 32GFC throughput with sophisticated hardware offloads that free processing power for core applications. It’s an ideal choice for enterprises running virtualization, large databases, ERP systems, and high-availability storage environments where predictability, reliability, and efficiency matter most. By combining dual-port resiliency with Gen 6 Fibre Channel efficiency, the QLE2742-CSC enables streamlined storage access across clustering, boot storms, backups, and disaster recovery scenarios while maintaining strong perfomance per watt in dense rack deployments.

• Gen 6 32GFC performance with dual ports: Experience blistering Fibre Channel throughput on both ports, reducing queue depth and improving IO completion times for frontline storage workflows and large-scale data migrations.
• Dual-port design for redundancy and multipathing: Two independent channels provide path diversity, enabling persistent availability and enhanced load distribution across the SAN fabric for uninterrupted service during maintenance or switchovers.
• Low CPU usage thanks to hardware offloads: Offloaded FC protocol processing minimizes host CPU overhead, allowing servers to allocate more cycles to virtual machines, databases, analytics, and other compute-intensive tasks.
• Enterprise-grade reliability and data integrity: Engineered to withstand demanding enterprise workloads with robust error detection, retry logic, and stable operation under heavy I/O bursts typical of consolidation and virtualized environments.
• Flexible deployment with broad compatibility: Designed to integrate with leading storage arrays and SAN fabrics, supported by vendor-provided drivers and management tooling for straightforward deployment across heterogeneous environments.
