Configuring VMware vSphere with PowerStore
Storage in a Multiple Cluster Configuration
Use the listed recommended values when multiple clusters are connected to vSphere.
The following table lists the recommended vSphere settings when multiple storage clusters are connected to vSphere (in
addition to PowerStore). Follow these recommendations instead of other recommendations in this chapter.
For reference, this table also includes the corresponding recommendations for settings when vSphere is connected to
PowerStore storage only.
