Elastic DRS uses an algorithm to maintain an optimal number of provisioned hosts to keep cluster utilization high while maintaining desired CPU, memory, and storage performance.
Elastic DRS monitors the current demand on your SDDC and applies an algorithm to make recommendations to either scale-in or scale-out the cluster. A decision engine responds to a scale-out recommendation by provisioning a new host into the cluster. It responds to a scale-in recommendation by removing the least-utilized host from the cluster.
- SDDCs deployed with multiple availability zone stretched clusters.
- Single host starter SDDCs
When the Elastic DRS algorithm initiates a scale-out, all Organization users receive a notification in the VMC Console and through email.
