摘要
随着云计算的日益普及,传统的烟囱式"三明治"扩展多层结构的单一IT系统组网无法适应满足现代大型数据中心多租户多系统的要求,本文参考思科和H3C公司提出的VMDC组网结构,给出了多租户IT支撑系统数据中心IP组网扁平化、接入无差异化的"精简多层"组网架构设计要点,并通过一则实际工程案例的设计运用予以介绍说明。实践证明,通过对精简多层组网结构的设计运用,能有效提高网络设备端口、带宽利用率,同时可满足多系统间安全域隔离及资源共享的需求。
With the growing popularity of cloud computing,the traditional extended multi-layer structure of a single IT system network,like a chimney "sandwich",can not meet the requirements of large-scale multi-tenant and multi-system in data center.In this paper,refer to Cisco and H3C VMDC network architecture,design points of compacted multi-layer structure for multi-tenant IT system data center network,which includes flattening network architecture,no differentiated access,etc,is mentioned.The design points are introduced by the use of the design of an actual project.Practice proved that through the use of compacted multi-layer structure design,can effectively improve the network device port,bandwidth utilization,and to meet the needs of multi-system security domain isolation and resource sharing.
