What are the two virtual switches of vSphere?
Today, I would like to talk to you about what the two virtual switches of vSphere are, which many people may not know. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something from this article.
Two types of virtual switches are supported in VMware vSphere 6.7:
1. Standard switch, VSS-Virtual Standard Switch
2. Distributed switch, VDS-Virtual Distributed Switch
VSS corresponds to ESXi hosts one by one, that is, a VSS can only be deployed on one ESXi host.
The distributed switch VDS is a switch that spans the entire data center, connecting all hosts together, but can only mount a maximum of 2000 hosts. In fact, a vCenter can only be in a physical network, such a deployment must be silly, but in the virtual world, it is feasible.
The figure above shows a VSS, a standard virtual switch, with two port groups set up: VMkernel and VM Network. The other side represents the network interface of the physical network card. Three virtual machines are deployed on this ESXi host: DNS Server, VCSA, and a VM template. It's all mounted on this switch. Click on 3 small black spots to view the detailed settings.
What's the difference between VSS and VDS? The following table makes a detailed summary.
After reading the above, do you have any further understanding of what are the two virtual switches of vSphere? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
