Cisco Unified Computing System Overview
The Cisco Unified Computing System™ is a next-generation data center platform that unites compute, network, storage access, and virtualization resources into a cohesive system designed to reduce total cost of ownership (TCO) and increase business agility. The system integrates a low-latency, lossless 10 Gigabit Ethernet unified network fabric with enterprise-class, x86-architecture servers. The system is an integrated, scalable, multichassis platform in which all resources participate in a unified management domain.
Product Overview
The Cisco® UCS NIC M51KR-B Broadcom BCM57711 Network Adapter (Figure 1) is a dual-port 10-Gbps KR Ethernet network adapter mezzanine card with an x8 PCI Express (PCIe) host interface. The KR interface and PCIe host interface interconnect on a single mezzanine connector. Designed specifically for the Cisco UCS blades, the adapter combines offload technology with standard Ethernet functions. Together, these features provide the performance and bandwidth critical to I/O-intensive applications such as virtualization and high-performance computing (HPC).

Why Cisco?
The Cisco Unified Computing System continues Cisco's long history of innovation in delivering integrated systems for improved business results based on industry standards and using the network as the platform. Recent examples include IP telephony, LAN switching, unified communications, and unified I/O. Cisco began the unified computing phase of our Data Center 3.0 strategy several years ago by assembling an experienced team from the computing and virtualization industries to augment our own networking and storage access expertise. As a result, Cisco delivered foundational technologies, including the Cisco Nexus® Family, supporting unified fabric and server virtualization. The Cisco Unified Computing System completes this phase, delivering innovation in architecture, technology, partnerships, and services. Cisco is well positioned to deliver this innovation by taking a systems approach to computing that unifies network intelligence and scalability with innovative application-specific circuits (ASICs,) integrated management, and standard computing components.
