VMWARE虚拟交换机配置

虚拟交换机分类
• 标准交换机
– 最基本的虚拟网络，属于单个服务器
• 分布式交换机
– 为虚机在不同服务器上迁移是提供一个始终如 一的网络配置
标准交换机
– 直连模式，虚机到虚机、虚机到物理网口 – 支持多网卡绑定 – 56个端口(4,088 maximum). – 一个虚机需要一个端口. – 上联网卡需要一个端口.

Distributed Switch Example
• Example:
– Create a distributed switch named Production, to be used for virtual machine networking. Assign uplinks, vmnic1 on host ESX01 and vmnic2 on host ESX02, to the distributed switch.
Connecting a Virtual Machine to a Port Group
Connect a virtual machine by assigning the port group to its network adapter.
Adding a Host to a Distributed Switch
• 分布式交换机功能
– 在分布式交换机上也可以配置vMotion、 Service Console
分布式交换机的好处
• The benefits of distributed switches over standard switches:
– Simplify datacenter administration – Provide support for private VLANs – Enable networking statistics and policies to migrate with virtual machines during a migration using VMware VMotion™ – Provide for customization and third-party development

Creating a Distributed Switch
• Right-click the distributed switch, then choose Add Host.
VMkernel and Service Console Connections
Use the Manage Virtual Adapters dialog box to add a new virtual adapter or to migrate an existing one to a distributed switch.
Adding a Network: Network Adapters
– Create a new virtual switch or add the connection type to an existing virtual switch.

• Different networks can coexist on the same virtual switch. Or they can exist on separate virtual switches. VMotion iSCSI
•
Enter name of switch, number of uplink ports, then choose the physical adapters from each host to add to the switch.
Viewing Distributed Switches
Use the Configuration tab to modify the switch.
– Name the connection and optionally define a VLAN ID (1–4,094) if using VLANs.
