as a physical network. This approach securely isolates each link and subjects each 
link to QoS controls as if the traffic were traversing its own physical cable (Figure 1).
Based on Open Standards and Accelerated by Silicon
Cisco has a tradition of using existing open standards (such as FCoE) and promoting 
new ones as necessary (such as the IEEE 802.1BR Bridge Port Extension standard). 
Cisco uses off-the-shelf silicon for common functions and designs custom silicon 
to incorporate Cisco innovations and to increase performance. Organizations gain 
the functional benefits of open-standard innovations with the improved performance 
that hardware implementations deliver (Figure 2).
The implications of the Cisco UCS I/O architecture are profound. The system is 
logically centralized with a single point of management for all I/O in the system: 
network, storage, and management. The system is physically distributed so that a 
single management domain can span both blade server chassis and racks, bringing 
up to 160 servers into what can be viewed as a single logical blade server chassis. 
The result is dramatically reduced cost and complexity compared to traditional rack 
and blade server deployments.
Advanced technology such as multihop FCoE and Cisco Direct Connect technology 
gives organizations the flexibility to integrate servers with shared storage as 
business needs dictate, without the limits of traditional network. Open-standards–
based separation between Ethernet traffic lanes helps ensure lossless handling of 
FCoE storage traffic and secure separation from other traffic types.
Cisco UCS Architecture
The new fabric components are essential to the Cisco UCS architecture because 
they provide a single point of connectivity and management for the entire system.
