Cisco VICs are PCIe-compliant interfaces that support up to 256 PCIe devices with
dynamically configured type (NIC or HBA), identity (MAC address or worldwide
name [WWN]), fabric failover policy, bandwidth, and QoS policy settings. With
Cisco VICs, server configuration—including I/O configuration—becomes configurable
on demand, making servers stateless resources that can be deployed to meet
any workload need at any time, without any physical reconfiguration or recabling
required. Cisco VICs support up to 80 Gbps of connectivity and are available in
multiple form factors:

• mLOM: These Cisco VICs can be ordered preinstalled in Cisco UCS M3 and
M4 blade servers, occupying a dedicated slot for the device . If more
than 40 Gbps of bandwidth is needed, a port expander card can be installed in
the server’s mezzanine slot to give the card access to an additional 40 Gbps of
bandwidth. When Cisco UCS 2304XP Fabric Extenders are installed in the blade
chassis, the Cisco UCS VIC 1340 detects the availability of 40 Gigabit Ethernet
and disables the port channel for greater efficiency.

• Mezzanine: Standard Cisco VICs can be installed in any blade server’s mezzanine
slot: one for half-width blade servers, and up to two for full-width blade servers.
Each Cisco VIC supports up to 80 Gbps, for a total of up to 320 Gbps of
aggregate bandwidth for double-width, double-height servers such as the Cisco
UCS C460 M4 Rack Server.

• PCIe: PCIe form-factor cards can be installed in Cisco rack servers. Cisco VICs
are required when you integrate these servers into Cisco UCS because they
have the circuitry to pass the unified fabric’s management traffic to the server’s
management network, enabling single-wire, unified management of rack servers.

Virtual links can originate from converged network adapters that typically host a
dual 10 Gigabit Ethernet NIC and a dual HBA from either Emulex or Q-Logic, along
with circuitry to multiplex the four streams of traffic onto two 10-Gbps unified fabric
links. Cisco innovations first brought this concept to market, with the first generation
of converged network adapters (CNAs) supported by Cisco silicon that multiplexed
multiple traffic flows onto the unified fabric.

With servers connected to Cisco UCS through CNAs, the traffic from each of the
interface’s four devices is passed over four virtual links that terminate at virtual ports
within the fabric interconnects.

The unified fabric virtualizes I/O so that rather than requiring each server to be
equipped with a set of physical I/O interfaces to separate network functions, all I/O
in the system is carried over a single set of cables and sent to separate physical
networks at the system’s fabric interconnects as necessary. For example, storage
traffic destined for Fibre Channel storage systems is carried in the system using
FCoE. At the fabric interconnects, storage-access traffic can transition to physical
Fibre Channel networks through a Fibre Channel transceiver installed in one or more
of the fabric interconnect’s unified ports.

I/O is further virtualized through the use of separate virtual network links for
each class and each flow of traffic. For example, management, storage-access,
and IP network traffic emanating from a server is carried to the system’s fabric
interconnects with the same level of secure isolation as if it were carried over
separate physical cables. These virtual network links originate within the server’s
converged network adapters and terminate at virtual ports within the system’s fabric
interconnects.

These virtual links are managed exactly as if they were physical networks. The
only characteristic that distinguishes physical from virtual networks within the
fabric interconnects is the naming of the ports. This approach has a multitude of
benefits: changing the way that servers are configured makes servers flexible,
adaptable resources that can be configured through software to meet any workload
requirement at any time. Servers are no longer tied to a specific function for
their lifetime because of their physical configuration. Physical configurations are
adaptable through software settings. The concept of virtual network links brings
immense power and flexibility to support almost any workload requirement through
flexible network configurations that bring complete visibility and control for both
physical servers and virtual machines.

The basic Cisco components of the UCS are:

UCS manager: Cisco UCS Manager implements policy-based management of the server and network resources. Network, storage, and server administrators all create service profiles, allowing the manager to configure the servers, adapters, and fabric extenders and appropriate isolation, quality of service (QoS), and uplink connectivity. It also provides APIs for integration with existing data center systems management tools. An XML interface allows the system to be monitored or configured by upper-level systems management tools.

UCS fabric interconnect: Networking and management for attached blades and chassis with 10 GigE and FCoE. All attached blades are part of a single management domain. Deployed in redundant pairs, the 20-port and the 40-port offer centralized management with Cisco UCS Manager software and virtual machine optimized services with the support for VN-Link.

Cisco Fabric Manager: manages storage networking across all Cisco SAN and unified fabrics with control of FC and FCoE. Offers unified discovery of all Cisco Data Center 3.0 devices as well as task automation and reporting. Enables IT to optimize for the quality-of-service (QoS) levels, performance monitoring, federated reporting, troubleshooting tools, discovery and configuration automation.

Fabric extenders: connect the fabric to the blade server enclosure, with 10 Gigabit Ethernet connections and simplifying diagnostics, cabling, and management. The fabric extender is similar to a distributed line card and also manages the chassis environment (the power supply, fans and blades) so separate chassis management modules are not required. Each UCS chassis can support up to two fabric extenders for redundancy.

Booting over a network (LAN or SAN) is a mature technology and an important step in moving toward stateless computing, which eliminates the static binding between a physical server and the OS and applications it is supposed to run.

The OS and applications are decoupled from the physical hardware and reside on the network.

The mapping between the physical server and the OS on the network is performed on demand when the server is deployed. Some of the benefits of booting from a network are:

• Reduced server footprint because fewer components (no disk) and resources are needed

• Simplified disaster and server failure recovery

• Higher availability because of the absence of failure-prone local hard drives

• Centralized image management

• Rapid redeployment With SAN booting, the image resides on the SAN, and the server communicates with the SAN through an HBA . The HBA’s BIOS contains the instructions that enable the server to find the boot disk. A common practice is to have the boot disk exposed to the server as LUN ID 0.

The Cisco UCS M71KR-E Emulex CNA, Cisco UCS M71KR-Q QLogic CNA, and Cisco UCS M81KR Virtual Interface Card (VIC) are all capable of booting from a SAN.

Management of Virtual Servers in the SAN Typically, virtual servers do not have an identity in the SAN: they do not log in to the SAN like physical servers do. However, if controlling and monitoring of the virtual servers is required, N-port ID virtualization (NPIV) can be used.

This approach requires you to:

• Have a Fibre Channel adapter and SAN switch that support NPIV

• Enable NPIV on the virtual infrastructure, such as by using VMware ESX Raw Device Mode (RDM)

• Assign virtual port worldwide names (pWWNs) to the virtual servers

• Provision the SAN switches and storage to allow access By zoning the virtual pWWNs in the SAN to permit access, you can control virtual server SAN access just as with physical servers. In addition, you can monitor virtual servers and provide service levels just as with any physical server.
