Virtual Cluster Switching (VCS) fabric technology is a Layer 2 proprietary Ethernet technology from Brocade Communications Systems designed to improve network utilization, maximize application availability, increase scalability, and simplify the network architecture in virtualized data centers. ==Ethernet Fabrics== Ethernet fabrics encompasses Data Center Bridging (DCB) technologies, IEEE 802.1aq and the emerging IETF standard, Transparent Interconnection of Lots of Links (TRILL), to provide a more efficient way of moving data throughout the network. An Ethernet fabric is promoted for Fibre Channel over Ethernet (FCoE) and iSCSI storage traffic. Ethernet fabrics have the following characteristics:〔(What_Are_Ethernet_Fabrics )〕 # Flatter: Ethernet fabrics are self-aggregating, enabling a flatter network. # Intelligent: Switches in the fabric know about each other and all connected devices. # Scalable: All paths are available for high performance and high reliability. # Efficient: Traffic automatically travels along the shortest path. # Simple: The fabric is managed as a single logical entity. Brocade markets using the term "Ethernet fabric".〔(Brocade First to Market with Ethernet Fabric Solutions to Enable Virtualized Data Centers and Cloud-Optimized Networks )〕 Brocade SAN fabric technology is currently deployed in over 90 percent of the Global 1000 data centers.〔(Brocade Corporate Fact Sheet )〕 With VCS Fabric technology, Brocade will be bringing the same level of innovation to the data center LAN environment. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Virtual Cluster Switching」の詳細全文を読む スポンサード リンク
