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 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, multi-chassis platform in which all resources participate in a unified management domain.

Product Overview

The Cisco® UCS CNA M72KR-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 high-performance connectivity for SAN and LAN traffic. One Cisco UCS M72KR-Q can do the work of a discrete Fibre Channel host bus adapter (HBA) and Ethernet network interface card (NIC). This convergence means fewer cables, fewer switches, less power consumption, reduced cooling, and unified LAN and SAN management.

Features and Benefits

The Cisco UCS M72KR-Q provides both 10 Gigabit Ethernet and 8-Gbps Fibre Channel functions using drivers from QLogic:

   Risk mitigation through compatibility with current QLogic adapter-based SAN environments and drivers

   Full hardware offload for FCoE protocol processing reduces system CPU utilization for I/O operations, which leads to faster application performance and higher levels of consolidation in virtualized systems

   Reduced TCO through consolidation of LAN and SAN traffic over the same mezzanine card and fabric, reducing the overall number of network interface cards (NICs), HBAs, cables, and switches

   Integrated management with Cisco UCS Manager

Table 1.       Features and Benefits



QLogic Fibre Channel controller application-specific integrated circuits (ASICs)

Allows customers to use existing QLogic HBA software and drivers for storage

Unified I/O

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

Network architecture

Provides redundant path to fabric interconnect using dual 10 Gigabit Ethernet ports to the fabric carrying both Fibre Channel and Ethernet traffic

Unified management

Through Cisco UCS Manager, automatically discovers blades and the mezzanine cards on the blades

Support for lossless Ethernet

Uses priority flow control (PFC) and IEEE 802.3x Pause to enable FCoE as part of the Cisco unified fabric

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.
