Cisco Unified Computing System Overview
® Unified Computing System is a next-generation data center platform that unites compute, network, storage access, and virtualization 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.
The Cisco UCS M71KR-Q QLogic Converged Network Adapter (CNA) is a QLogic-based Fibre Channel over Ethernet (FCoE) mezzanine card that provides connectivity for Cisco UCS B-Series Blade Servers in the Cisco Unified Computing System.
Designed specifically for the Cisco UCS blades, the adapter provides a dual-port connection to the midplane of the blade server chassis. The Cisco UCS M71KR-Q uses an Intel 82598 10 Gigabit Ethernet controller for network traffic and a QLogic 4-Gbps Fibre Channel controller for Fibre Channel traffic, all on the same mezzanine card. The Cisco UCS M71KR-Q presents two discrete Fibre Channel host bus adapter (HBA) ports and two Ethernet network ports to the operating system (Figure 1).
Allows customers to use existing QLogic HBA software and drivers for storage
Helps reduce TCO by consolidating the overall number of NICs, HBAs, cables, and switches because LAN and SAN traffic run over the same mezzanine card and fabric
Provides redundant path to fabric interconnect using dual 10 Gigabit Ethernet ports to the fabric carrying both Fibre Channel and Ethernet traffic
Through Cisco UCS Manager, automatically discovers blades and the mezzanine cards on the blades
Intel 82598 ASIC for Ethernet traffic
Delivers efficient, high-performance Ethernet support
Support for lossless Ethernet
Uses priority flow control (PFC) and IEEE 802.3x Pause to enable FCoE as part of the Cisco unified fabric
Support for Fibre Channel N-port ID virtualization (NPIV) sessions
Support 16 sessions of Microsoft Windows operating systems and 64 for Linux operating systems
Platform Support and Compatibility
The Cisco UCS M71KR-Q mezzanine card is designed specifically for Cisco UCS B-Series Blade Servers and works in a dedicated environment with Cisco UCS Manager.

The Cisco UCS M71KR-Q is a mezzanine card designed to be used only on Cisco UCS B-Series Blade Servers. Each Cisco UCS B200 M1 2-Socket Blade Server supports one mezzanine adapter, and each Cisco UCS B250 M1 2-Socket Extended-Memory Blade Server supports up to two adapters. The adapters are not designed or intended for other purposes.

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 ASICs, integrated management, and standard computing components.
