Managing Network Adapters

This chapter includes the following sections:

Overview of the Cisco UCS C-Series Network Adapters


Note

The procedures in this chapter are available only when a Cisco UCS C-Series network adapter is installed in the chassis.

A Cisco UCS C-Series network adapter can be installed to provide options for I/O consolidation and virtualization support. The following adapters are available:

  • Cisco UCS P81E Virtual Interface Card
  • Cisco UCS VIC1225 Virtual Interface Card

The interactive UCS Hardware and Software Interoperability Utility lets you view the supported components and configurations for a selected server model and software release. The utility is available at the following URL: http://www.cisco.com/web/techdoc/ucs/interoperability/matrix/matrix.html

Cisco UCS P81E Virtual Interface Card

The Cisco UCS P81E Virtual Interface Card is optimized for virtualized environments, for organizations that seek increased mobility in their physical environments, and for data centers that want reduced costs through NIC, HBA, cabling, and switch reduction and reduced management overhead. This Fibre Channel over Ethernet (FCoE) PCIe card offers the following benefits:

  • Allows up to 16 virtual Fibre Channel and 16 virtual Ethernet adapters to be provisioned in virtualized or nonvirtualized environments using just-in-time provisioning, providing tremendous system flexibility and allowing consolidation of multiple physical adapters.
  • Delivers uncompromising virtualization support, including hardware-based implementation of Cisco VN-Link technology and pass-through switching.
  • Improves system security and manageability by providing visibility and portability of network polices and security all the way to the virtual machine.

The virtual interface card makes Cisco VN-Link connections to the parent fabric interconnects, which allows virtual links to connect virtual NICs in virtual machines to virtual interfaces in the interconnect. In a Cisco Unified Computing System environment, virtual links then can be managed, network profiles applied, and interfaces dynamically reprovisioned as virtual machines move between servers in the system.

Cisco UCS VIC1225 Virtual Interface Card

The Cisco UCS VIC1225 Virtual Interface Card is a high-performance, converged network adapter that provides acceleration for the various new operational modes introduced by server virtualization. It brings superior flexibility, performance, and bandwidth to the new generation of Cisco UCS C-Series Rack-Mount Servers.

The Cisco UCS VIC 1225 implements the Cisco Virtual Machine Fabric Extender (VM-FEX), which unifies virtual and physical networking into a single infrastructure. It provides virtual-machine visibility from the physical network and a consistent network operations model for physical and virtual servers. In virtualized environments, this highly configurable and self-virtualized adapter provides integrated, modular LAN interfaces on Cisco UCS C-Series Rack-Mount Servers. Additional features and capabilities include:

  • Supports up to 256 PCIe virtual devices, either virtual network interface cards (vNICs) or virtual host bus adapters (vHBAs), with high I/O operations per second (IOPS), support for lossless Ethernet, and 20 Gbps to servers.
  • PCIe Gen2 x16 helps assure optimal bandwidth to the host for network-intensive applications with a redundant path to the fabric interconnect.
  • Half-height design reserves full-height slots in servers for Cisco certified third-party adapters.
  • Centrally managed by Cisco UCS Manager with support for Microsoft Windows, Red Hat Enterprise Linux, SUSE Linux, VMware vSphere, and Citrix XenServer.

                        Name Description

                        Enable TCP Segmentation Offload check box

                        If checked, the CPU sends large TCP packets to the hardware to be segmented. This option may reduce CPU overhead and increase throughput rate.

                        If cleared, the CPU segments large packets.

                        Note

                        Enable Large Receive check box

                        If checked, the hardware reassembles all segmented packets before sending them to the CPU. This option may reduce CPU utilization and increase inbound throughput.

                        If cleared, the CPU processes all large packets.
                        Step 14   In the Receive Side Scaling area, review the information in the following fields:

                              Virtual Machine Fabric Extender

                              Cisco Virtual Machine Fabric Extender (VM FEX) extends the (prestandard) IEEE 802.1Qbh port extender architecture to virtual machines. In this architecture, each VM interface is provided with a virtual Peripheral Component Interconnect Express (PCIe) device and a virtual port on a switch.

                              Viewing Virtual FEX Properties

                              Before You Begin
                              • The server must be powered on, or the properties will not display.
                              • A supported Virtual Interface Card (VIC) must be installed in the chassis and the server must be powered on.
                              Procedure
                                Step 1   In the Navigation pane, click the Server tab.

                                If enabled, the CPU sends all packets to the hardware so that the checksum can be calculated. If disabled, the CPU calculates all packet checksums.

                                Enable Large Receive field

                                If enabled, the hardware reassembles all segmented packets before sending them to the CPU. If disabled, the CPU processes all large packets.
                                Step 15   In the Receive Side Scaling area, review the information in the following fields:

                                Receive Side Scaling (RSS) distributes network receive processing across multiple CPUs in multiprocessor systems.

                                If enabled, network receive processing is shared across processors whenever possible. If disabled, network receive processing is always handled by a single processor even if additional processors are available.

                                Enable IPv4 RSS field

                                If enabled, RSS is enabled on IPv4 networks.

                                If enabled, RSS is enabled on IPv6 networks.

                                Enable TCP-IPv6 RSS field

                                If enabled, RSS is enabled for TCP transmissions across IPv6 networks.

                                Enable IPv6 Extension RSS field

                                If enabled, RSS is enabled for IPv6 extensions.

                                Enable TCP-IPv6 Extension RSS field

                                If enabled, RSS is enabled for TCP transmissions across IPv6 networks.
