8.6.3 Examples of environment settings for a VMware ESXi-based virtualization environment

When a VMware ESXi-based virtualization environment is used, the settings to be specified in the definition files depend on the resources and functions that are used. This subsection explains typical examples of system configurations for VMware ESXi-based virtualization environments and the settings to be specified in the definition files for each system configuration.

Organization of this subsection

(1) Example of environment settings when resetting hosts
(2) Example of environment settings when using SCSI reservation for shared disk (redundant configuration using multipath software)
(3) Example of environment settings using the function for controlling hot standby based on the availability of LAN communications

(1) Example of environment settings when resetting hosts

The following figure shows a system configuration for an example of environment settings when resetting hosts.
