Vsphere basic operations-network

1. vsphere Network Operations

Concept:

Portgroup: communication port group. There are three port groups in vsphere.

1) Management Network: Management Network, which can be understood as the management IP address of the exsi host. Each exsi must be configured with a management network IP address so that the VC can manage to exsi. Each exsi can have only one unique management network.

2) kernel: vmkernel, which can be understood as the backend IP address of exsi, enabling various backend functions. The backend functions mentioned here refer to the log records of exsi communication to achieve advanced functions such as vmotion, iSCSI connection, NAS storage, and FT functions. The performance in esxi is vmk0 ~ N

3) Virtual Machine Communication Port Group: VM is used to enable the VM to communicate with the real switch.

After the exsi host is installed, a vswitch0 is created in vmnic0, and a management netwrok and a vmkernel are created on the vswitch.

 

Routine Network Operations

In daily vsphere network management, we usually perform the following operations:

1) create multiple vswitches. Each vswitch is allocated with a different vmvic (physical Nic) for communication between different VMS on different VLANs. If multiple vswitches are created, make sure that each exsi host has the same vswitch configuration. Otherwise, advanced functions such as vmotion cannot be implemented.

2) create multiple vmkernel to implement different backend functions. If one can be allocated to iSCSI and the other to vmotion communication.

3) create a VDS distributed switch and migrate the management network, kernel, and Virtual Machine Communication Group.

4) create different Virtual Machine Communication Port groups for different VMS.

5) Nic teaming. Aggregation of physical NICs
