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:
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.

Managing Cisco usNIC
Overview of
Cisco usNIC
The Cisco user-space
NIC (Cisco usNIC) feature improves the performance of software applications that run
on the
Cisco UCS servers in your data center by bypassing the kernel when sending and
receiving networking packets. The applications interact directly with a
Cisco UCS VIC second generation adapter, such as the
Cisco UCS VIC-1280, which improves the networking performance of your high-performance
computing cluster. To benefit from
Cisco usNIC, your applications must use the Message Passing Interface (MPI)
instead of sockets or other communication APIs.
Cisco usNIC offers the following benefits for your MPI applications:
Provides a
low-latency and high-throughput communication transport.
Employs the
standard and application-independent Ethernet protocol.
Takes advantage
of lowÂlatency forwarding, Unified Fabric, and integrated management support in
the following Cisco data center platforms:
Cisco UCS server
Cisco UCS VIC second generation adapter, such as the
Cisco UCS VIC-1280
10GbE network
Standard Ethernet
applications use user-space socket libraries, which invoke the networking stack
in the Linux kernel. The networking stack then uses the Cisco eNIC driver to
communicate with the Cisco VIC hardware. The following figure shows the
contrast between a regular software application and an MPI application that
uses usNIC.
Figure 1. Kernel-Based Network Communication versus
Cisco usNIC-Based Communication
Configuring Cisco usNIC Using the CIMC GUI
Note
Even though several properties are listed for Cisco usNIC in the usNIC properties dialog box, you must configure only the following properties because the other properties are not currently being used.
cq-count
rq-count
tq-count
usnic-count
Before You Begin
You must log in to the CIMC GUI with administrator privileges to perform this task.
In the Inventory pane, click the Cisco VIC Adapters tab.
Step 5
In the Adapter Cards area, select the adapter card.
If the server is powered on, the resources of the selected adapter card appear in the tabbed menu below the Adapter Cards area.
Step 6
In the tabbed menu below the Adapter Cards area, click the vNICs tab.
Step 7
In the Host Ethernet Interfaces area, select a vNIC from the table.
Note
For each vNIC that you want to configure as a usNIC, select the vNIC entry from the table and specify its properties as explained in steps 9 through step 18.
Step 8
Click usNIC to open the usNIC Properties dialog box.
Step 9
In the usNICs property, specify the number of Cisco usNICs that you want to create.
Each MPI process that is running on the server requires a dedicated usNIC. You might need to create up to 64 usNICs to sustain 64 MPI processes running simultaneously. We recommend that you create at least as many usNICs, per
usNIC-enabled vNIC, as the number of physical cores on your server. For example, if you have 8 physical cores on your server, create 8 usNICs.
Step 10
In the Properties area, update the following fields:
Field Name
Description
Transmit Queue Count
The number of transmit queue resources to allocate.
MPI will use 2 transmit queues per process. Therefore, Cisco recommends
that you set this value to 2.
Receive Queue Count
The number of receive queue resources to allocate.
MPI will use 2 receive queues per process. Therefore, Cisco recommends
that you set this value to 2.
Completion Queue Count
The number of completion queue resources to allocate. In general, the number of completion queue resources you should allocate is equal to the number of transmit queue resources plus the number of receive queue resources.
Cisco recommends that you set this value to 4.
Step 11
Click Apply.
Step 12
In the
Navigation pane, click the
Server tab.
Step 13
On the Server tab, click BIOS.
Step 14
