配置分布式交换机
分布式交换机与普通交换机相同之处
1.like a vswitch,a vnetwork distributed switch provides connectivity for virutal machines,service console or management traffic,and vmkernel interfaces.
2.like a vswitch,a vnetwork distributed switch leverages physical network adapters as uplinks to provide connectivity to the external physical network.
3.like a vswitch,a vnetwork distributed switch can leverage vlans for logical network segmentation.
分布式交换机的优点
vnetwork distributed switch spans multiple servers in a cluster instead of each server having itsown set of vswitches.this greatly reduces complexity in clustered esx/esxi environments and simplifies the addition of new servers to an esx/esxi cluster.(分布式交换机能够分布在多个服务器集群里面来取代以前你需要在以前在每个服务器上创建标准交换机,分布式交换机可以跨越很多esxi主机.
不同版本分布式交换机的比较
1.vsphere distributed switch version:4.0:this type of dvswitch is compatible back to vsphere 4.0 and limits the dvswitch to features supported only by vsphere 4.0.(没有多个功能,管理上的优势)
2.vsphere distributed switch version:4.1.0:this type of dvswitch adds support for load-based teaming and network i/op control.this version is supported by vsphere 4.1 and later.(有负载均衡,网络i/o吞吐量的控制)
3.vsphere distributed switch version:5.0.0:this version is compatible only with vsphere 5.0 and later and adds support for all the features such as userdefined network resource pools,network i/o control,netflow,and port mirroring(可以让用户定义网络资源池,通过网络资源池来控制网络i/o带宽,netflow,和端口镜像)
