Cisco UCS CNA M73KR-Q QLogic Converged Network Adapter Data Sheet
Available Languages
Product Overview
The Cisco UCS™ CNA M73KR-Q QLogic Converged Network Adapter (CNA; Figure 1) 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™ (Cisco UCS).
Designed specifically for the Cisco UCS blades, the adapter provides high-performance connectivity for SAN and LAN traffic. One Cisco UCS CNA M73KR-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 CNA M73KR-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, reducing system CPU utilization for I/O operations and leading to faster application performance and greater consolidation in virtualized systems
● Reduced total cost of ownership (TCO) through consolidation of LAN and SAN traffic over the same mezzanine card and fabric, reducing the overall number of NICs), HBAs, cables, and switches
● Integrated management with Cisco UCS Manager
Figure 2 shows the Cisco UCS CNA M73KR-Q architecture.
Table 1 summarizes the features and benefits of the Cisco UCS CNA M73KR-Q.
Table 1. Features & Benefits
| Feature |
Benefit |
| QLogic Fibre Channel controller application-specific integrated circuits (ASICs) |
Allows customers to use existing QLogic HBA software and drivers for storage |
| Unified I/O |
● Supports three simultaneous protocols: TCP/IP networking, FCoE, and Small Computer System Interface over IP (iSCSI)
● 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, supports automatic updates of Qlogic firmware and drivers. |
| Support for lossless Ethernet |
● Uses Priority Flow Control (PFC) and IEEE 802.3x pause to enable FCoE as part of the Cisco unified fabric
● Increases storage networking performance by eliminating retry and resend operations in congested fabrics
