About the Cisco USCS-PCIE-C40Q-03 Cisco UCS C-Series rack server / component
The Cisco USCS-PCIE-C40Q-03 is a high-performance PCIe adapter card engineered for Cisco UCS C-Series rack servers, delivering enterprise-grade network connectivity without the power overhead of external switching infrastructure. This genuine Cisco component integrates seamlessly into existing UCS deployments, enabling network engineers and infrastructure architects to scale 40 Gigabit Ethernet capacity within their existing server footprint while maintaining operational efficiency through intelligent offload capabilities.
Built on the Chelsio T5 ASIC, the USCS-PCIE-C40Q-03 offloads critical network functions including TCP Segmentation Offload (TSO), Large Receive Offload (LRO), iSCSI offload, and RoCE processing—reducing CPU utilization and improving application performance across virtualized and bare-metal environments. The adapter integrates directly with Cisco UCS Manager for unified lifecycle management and supports SR-IOV virtualization, allowing multiple virtual machines to share a single physical adapter without performance degradation. IT procurement teams standardizing on Cisco infrastructure will appreciate native compatibility with VMware ESXi, Red Hat Enterprise Linux, and Windows Server operating systems, eliminating driver complexity and validation delays.
