Overview
Adapter Cards
up to 128 Peripheral Component Interconnect Express (PCIe) standards-compliant virtual interfaces that can be dynamically configured so that both their interface type (network interface 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.
The Cisco UCS M81KR is designed for both traditional operating system and virtualization environments. It is optimized 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.
The Cisco UCS M81KR presents up to 128 virtual interfaces to the operating system on a given blade. The 128 virtual interfaces can be dynamically configured by Cisco UCS Manager as either Fibre Channel or Ethernet devices. Deployment of applications using multiple Ethernet and Fibre Channel interfaces is no longer constrained by the available physical adapters. To an operating system or a hypervisor running on a Cisco UCS B-Series Blade Server, the virtual interfaces appear as regular PCIe devices.
The Cisco UCS M81KR has built-in architectural support enabling the virtual machine to directly access the adapter. I/O bottlenecks and memory performance can be improved by providing virtual machines direct access to hardware I/O devices, eliminating the overhead of embedded software switches.
The Cisco UCS M81KR also brings adapter consolidation to physical environments. The adapter can be defined as multiple different NICs and HBAs. For example, one adapter card can replace two quad-port NICs and two single-port HBAs, resulting in fewer NICs, HBAs, switches, and cables.
Cisco UCS 82598KR-CI 10 Gigabit Ethernet Adapter
The Cisco 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 center environments that need low-latency 10 Gigabit Ethernet transport capability, and a dual-port connection to the midplane of the blade server chassis.
The Cisco UCS 82598KR-CI supports Intel Input/Output Acceleration Technology (I/OAT) as well as virtual queues for I/O virtualization. The adapter is energy efficient and can also help reduce CPU utilization by providing large segment offload (LSO) and TCP segmentation offload (TSO). The Cisco UCS 82598KR-CI uses Intel Virtual Machine Device Queue (VMDq) technology for the efficient routing of packets to the appropriate virtual machine.
Cisco UCS M71KR-E Emulex Converged Network Adapter
The Cisco UCS M71KR-E Emulex Converged Network Adapter (CNA) is an Emulex-based Fibre Channel over Ethernet (FCoE) adapter 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-E uses an Intel 82598 10 Gigabit Ethernet controller for network traffic and an Emulex 4-Gbps Fibre Channel controller for Fibre Channel traffic all on the same adapter card. The Cisco UCS M71KR-E presents two discrete Fibre Channel host bus adapter (HBA) ports and two Ethernet network ports to the operating system.
The Cisco UCS M71KR-E provides both 10 Gigabit Ethernet and 4-Gbps Fibre Channel functions using drivers from Emulex, providing:
