Scalability: vCLS is designed to scale easily, so it can be used to manage even the largest vSphere clusters. If vCLS health gets impacted due to unavailability of these VMs in a cluster, then vSphere DRS will not be functional in the cluster until the time vCLS VMs are brought back up. The vSphere Clustering Service (vCLS) is a new capability that is introduced in the vSphere 7 Update 1 release. Since vCLS VMs are deployed as soon as a first host is added to a new cluster, any test scripts to validate empty cluster in a greenfield deployment should have to be change. 1. 1. vSphere HA guarantees the restart only when it has a cluster quorum and can access the most recent copy of the virtual machine object. I recently deployed vCenter HA 7. 8 GB of available space. Reply. This part will introduce the detailed steps to create an efficient vSphere High Availability.
