WHAT IS AN ETHERNET FABRIC?
Compared to classic hierarchical Ethernet 
architectures, Ethernet fabrics provide
higher levels of performance, utilization,
availability, and simplicity. They are
designed to be:
• Flatter:
 Eliminates the need for 
Spanning Tree Protocol (STP), while
being completely interoperable with
existing Ethernet networks
• Flexible:
Can be architected in any
topology to best meet the needs  
of any variety of workloads
• Resilient:
Uses multiple “least cost”
paths for high performance and  
high reliability
• Elastic:
Scales easily up and down  
as needed
More advanced Ethernet fabrics  
borrow further from Fibre Channel  
fabric constructs:
• They are self-forming and function
as a single logical entity, in which all
switches automatically know about
each other and all connected physical
and logical devices. 
• Management can then be domain-
based rather than device-based, and
defined by policy rather than repetitive
procedures.
• These features, along with
virtualization-specific enhancements,
make it easier to explicitly address  
the challenges of VM automation  
within the network, thereby facilitating
better IT automation.
• Protocol convergence, such as Fibre
Channel over Ethernet (FCoE), may also
be a feature, intended as a means of
better bridging LAN and Storage Area 
Network (SAN) traffic.

Compared to classic Ethernet architectures, Ethernet fabrics allow all paths to be active
and provide greater scalability—while reducing management complexity.
