Cisco Unified Computing System Overview
The Cisco Unified Computing System™ (Cisco UCS®) is a next-generation, 40-Gbps data center platform that unites computing, network, storage access, and virtualization resources into a cohesive system designed to reduce total cost of ownership (TCO) and increase business agility. The system integrates a low-latency, lossless 40/10- Gbps Ethernet unified network fabric with enterprise-class, x86-architecture servers. The system is an integrated, scalable, multichassis platform in which all resources participate in a unified management domain.
The Cisco UCS Virtual Interface Card (VIC) 1340 (Figure 1) is a 2-port 40-Gbps Ethernet or dual 4 x 10-Gbps Ethernet, Fibre Channel over Ethernet (FCoE)-capable modular LAN on motherboard (mLOM) designed exclusively for the M4 generation of Cisco UCS B-Series Blade Servers. When used in combination with an optional port expander, the Cisco UCS VIC 1340 capabilities is enabled for two ports of 40-Gbps Ethernet.
The Cisco UCS VIC 1340 enables a policy-based, stateless, agile server infrastructure that can present over 256 PCIe standards-compliant interfaces to the host that can be dynamically configured as either network interface cards (NICs) or host bus adapters (HBAs). In addition, the Cisco UCS VIC 1340 supports Cisco® Data Center Virtual Machine Fabric Extender (VM-FEX) technology, which extends the Cisco UCS fabric interconnect ports to virtual machines, simplifying server virtualization deployment and management.

Features and Benefits
Stateless and Agile
The personality of the card is determined dynamically at boot time using the service profile associated with the server. The number, type (NIC or HBA), identity (MAC address and World Wide Name [WWN]), failover policy, bandwidth, and quality-of-service (QoS) policies of the PCIe interfaces are all determined using the service profile. The capability to define, create, and use interfaces on demand provides a stateless and agile server infrastructure (Figure 2).

Next-Generation Data Center Features
Hardware classification engine provides support for advanced data center requirements including stateless network offloads for NVGRE and VXLAN (VMware only), low-latency features for usNIC and RDMA, and performance optimization applications such as VMQ, DPDK, and Cisco NetFlow.
Network interface virtualization: Each PCIe interface created on the VIC is associated with an interface on the Cisco UCS fabric interconnect, providing complete network separation for each virtual cable between a PCIe device on the VIC and the interface on the fabric interconnect.
Cisco SingleConnect Technology
Cisco SingleConnect technology provides an exceptionally easy, intelligent, and efficient way to connect and manage computing in the data center. Cisco SingleConnect technology is an exclusive Cisco innovation that dramatically simplifies the way that data centers connect to:
● Rack and blade servers
● Physical servers and virtual machines
● LAN, SAN, and management networks
The solution addresses the challenges of today’s data center, and the result is a simple, intelligent, and efficient fabric:
● Easy: Cisco SingleConnect technology provides a “wire once and walk away” solution that eliminates traditional manual, time-consuming, error-prone processes and instead makes connecting servers to Cisco UCS fast and easy.
● Intelligent: The technology is intelligent because it uses a zero-touch model to allocate I/O connectivity (LAN, SAN, and management) across any type of server: physical rack and blade servers and virtual machines. The network intelligence helps Cisco UCS adapt to the needs of applications. Rather than limiting applications to specific servers, Cisco UCS makes it easy to run any workload on any server.
● Efficient: The technology is highly efficient because LAN, SAN, and management connections are shared over a single network, increasing utilization while reducing the number of moving parts compared to traditional approaches with multiple networks.
Cisco SingleConnect technology is implemented with an end-to-end system I/O architecture that uses Cisco Unified Fabric and Cisco Fabric Extender Technology (FEX Technology) to connect every Cisco UCS component with a single network and a single network layer. As customers expect from Cisco, the Cisco UCS I/O architecture is based on open standards and is reliable, available, and secure.
Cisco Data Center VM-FEX Technology
Cisco Data Center VM-FEX technology extends fabric interconnect ports directly to virtual machines, eliminating software-based switching in the hypervisor. Cisco Data Center VM-FEX technology collapses virtual and physical networking infrastructure into a single infrastructure that is fully aware of the virtual machines’ locations and networking policies (Figure 3). Cisco Data Center VM FEX technology is implemented by Cisco VICs with a prestandard implementation of the IEEE 802.1BR Port Extender standard.

Table 1. Features and Benefits
x16 PCIe Gen3 interfaces
Delivers greater throughput
2 ports of 40-Gbps unified I/O
2 sets of 4 x 10-Gbps unified I/O
● Delivers 80 Gbps to the server
● Helps reduce TCO by consolidating the overall number of NICs, HBAs, cables, and switches because LAN and SAN traffic runs over the same mezzanine card and fabric
● Adapts to either 10-Gbps or 40-Gbps fabric connections
Over 256 dynamic virtual adapters and interfaces
Creates fully functional unique and independent PCIe adapters and interfaces (NICs or HBAs) without requiring single-root I/O virtualization (SR-IOV) support from OSs or hypervisors
● Allows these virtual interfaces and adapters to be configured and operated independently, just like physical interfaces and adapters
● Creates a highly flexible I/O environment needing only one card for all I/O configurations
Note: Cisco UCS VIC 1340 hardware is SR-IOV capable, and you can enable SR-IOV after SR-IOV is broadly supported by the popular operating systems. Please refer to UCS Manager configuration limits for your specific OS and environment in the configuration guide.
