upto 128 Peripheral Component Interconnect Express (PCIe) standards-compliant virtual interfaces that can
bedynamically configured so that both their interface type (networkinterface card [NIC] or host bus adapter
[HBA])and identity (MAC address and worldwide name [WWNN]) are established using just-in-time
provisioning.In addition, the Cisco UCS M81KR supports network interface virtualization and Cisco VN-Link
technology.
TheCisco UCS M81KR is designed for both traditional operating system and virtualization environments. It
isoptimized for virtualized environments, for organizations that seek increased mobility in their physical
environments,and for data centers that want reduced TCO through NIC, HBA, cabling, and switch reduction.
TheCisco UCS M81KR presents up to 128 virtual interfaces to the operating system on a given blade. The
128virtual interfaces can be dynamically configured by Cisco UCS Manager as either Fibre Channel or
Ethernetdevices. Deployment of applications using multiple Ethernet and Fibre Channel interfaces is no
longerconstrained by the available physical adapters. To an operating system or a hypervisor running on a
CiscoUCS B-Series Blade Server,the virtual interfaces appear as regular PCIe devices.
TheCisco UCS M81KRhas built-inarchitectural support enablingthe virtual machineto directlyaccess the
adapter.I/O bottlenecks and memory performance can be improved by providing virtual machines direct
accessto hardware I/O devices, eliminating the overhead of embedded software switches.
TheCisco UCS M81KR also brings adapter consolidation to physical environments. The adapter can be
definedas multiple different NICs and HBAs. For example, one adapter card can replace two quad-port NICs
andtwo single-port HBAs, resulting in fewer NICs, HBAs, switches, and cables.
Cisco UCS 82598KR-CI 10 Gigabit Ethernet Adapter
TheCisco UCS 82598KR-CI 10 Gigabit Ethernet adapter is based on the Intel 82598 10 Gigabit Ethernet
controller,which is designed for efficient high-performance Ethernet transport. It provides a solution for data
centerenvironments that need low-latency 10 Gigabit Ethernet transport capability, and a dual-port connection
tothe midplane of the blade server chassis.
TheCisco UCS 82598KR-CI supports Intel Input/Output Acceleration Technology (I/OAT)as well as virtual
queuesfor I/O virtualization. The adapter is energy efficient and can also help reduce CPU utilization by
providinglarge segment offload (LSO) and TCP segmentation offload (TSO). The Cisco UCS 82598KR-CI
usesIntel Virtual Machine Device Queue (VMDq) technology for the efficient routing of packets to the
appropriatevirtual machine.
Cisco UCS M71KR-E Emulex Converged Network Adapter
TheCisco UCS M71KR-E Emulex Converged Network Adapter (CNA) is an Emulex-based Fibre Channel
overEthernet (FCoE) adapter card that provides connectivity for Cisco UCS B-Series Blade Servers in the
CiscoUnified Computing System.
Designedspecifically for the Cisco UCS blades, the adapter provides a dual-port connection to the midplane
ofthe blade server chassis. The Cisco UCS M71KR-Euses an Intel 82598 10Gigabit Ethernet controller for
networktraffic and an Emulex 4-Gbps Fibre Channel controller for Fibre Channel traffic all on the same
adaptercard. The Cisco UCS M71KR-E presents two discrete Fibre Channel host bus adapter (HBA) ports
andtwo Ethernet network ports to the operating system.
TheCisco UCS M71KR-E provides both 10 Gigabit Ethernet and 4-Gbps Fibre Channel functions using
driversfrom Emulex, providing:
