Proactive DRS

New tool has been released by VMware Lab about better resource load balancing in a vSphere cluster.

Its name can explain, what’s its mission?! I’ll publish a post about installation and configuration. You can download it from:

What is ProactiveDRS? It is a way for DRS to  react to changes in the virtual cluster, and to act on predicted changes in resource demands before hosts become stressed. For example, if you have a VM that historically uses 100% CPU at 8am every morning, ProactiveDRS  makes  sure that the CPU resources will be available for that VM before 8am. These actions ensure that your cluster runs smoother and reduces the amount of reactive VM rebalances that occur.
