IEEE 802.1 Data Center Bridging (DCB) is a collection of standards-based extensions to classical Ethernet. It provides a lossless data center transport layer that helps enable the convergence of LANs and SANs onto a single unified fabric.
The DCB framework defines the capabilities for switches and endpoints to be part of a data center fabric. It includes:
Cisco has pioneered and is leading the development of important data center bridging concepts and facilities within the IEEE, IETF, and ANSI T.11 standards bodies. These efforts are helping to develop and promote multivendor, interoperable data center solutions.
Keep it simple: infrastructure, cable management, reduced power and cooling costs.
Cisco Unified Computing System unites network, computing, and virtualization.
Make data center infrastructure more flexible with Cisco Unified Fabric.
