single network hop, simplifying virtual machine placement.

Ready for a 40-Gbps data center: Whether you use Cisco Nexus 7000 or 9000
Series Switches, this fabric upgrade prepares you for 40-Gbps speeds. If you
have deployed Cisco ACI in your data center, Cisco UCS is ready to interconnect
servers and virtual machines and appliances through the Cisco ACI fabric’s
encapsulation normalization mechanisms.

Cisco UCS Fabric for the Future
The Cisco UCS network fabric is implemented with an end-to-end 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. The result is a single, large, virtual blade server chassis that can accommodate
both blade and rack servers and connect any two entities, physical or virtual, with a
single network hop.

Single Unified Network
The same network brings LAN, SAN, and management connectivity to each rack
and blade server in Cisco UCS using Cisco Unified Fabric. Now every server—rack
or blade—has equal access to all network resources, eliminating the need to support
three physical networks, each with its own network interface cards (NICs), host bus
adapters (HBAs), transceivers, cables, and top-of-rack switches. Infrastructure silos
are eliminated because software—not cabling—determines the way that each server
connects to the network, making every server ready to support any workload at a
moment’s notice through automated configuration.

This “wire once” capability is a core feature of Cisco UCS: you can wire your system
once for the bandwidth you require, and add features (such as access to shared
storage) through software, not more cabling. If you need more bandwidth for any
I/O modality, you add more cables, not more infrastructure. Consistent forwarding
policies using technologies such as VLANs and QoS controls align your networking
features and performance with business needs.

Single Network Layer
A single network layer brings the unified fabric to every blade chassis and server
rack. FEX Technology reduces three network layers to one, eliminating hypervisor
switches and blade-chassis-resident switches and replacing them with a single
point of management and connectivity (Figure 1). In Cisco UCS, low-cost, low-
power, and zero-management Cisco UCS and Cisco Nexus fabric extenders pass
all traffic from servers and virtual machines to the system’s fabric interconnects. This
