- Given an advance forecast/prediction of each VM’s resource demands, e.g., CPU and Memory, ProactiveDRS seeks to reorganize the placement of VMs to best balance the current resource demands while taking early actions to accommodate the future/predicted resource demands.
- Sample actions include, but are not limited to, proactive vMotions (migrations) and proactively powering on a new physical host to accept VMs whose resource demands are expected to spike beyond the available resources of their current physical host.
You need to have DRS and VMware Operations Manager (vC Ops) v5.6 or newer installed.
Install the Proactive DRS fling released by VMware Inc. at VMworld 2013. The Proactive DRS Fling provides a mechanism to use the VMware Distributed Resource Scheduler product ("DRS") in proactive mode.
- Download and install vSphere 5.5 Virtual Center - the Virtual Center Virtual Appliance ("VCVA") is recommended.
- Download and install VMware Operations Manager (vC Ops) v5.6 or newer.
- Configure the vC Ops instance to manage the VC installed in step #1.
- Download this fling VM onto a location from where it is able to communicate ("ping") with the vC Ops UI VM and the vSphere 5.5 VCVA.
- Power-on the fling VM, read the README.txt file on the desktop to understand any additional setup details.
- Launch the fling by opening the link on the Desktop and follow its simple instructions to enter vC Ops and VC credentials.
- Once the fling creates/transports predicted.stats files and begins counting down the time to its next invocation, Proactive DRS is ready for use.
- In your VC, set the value of the new DRS advanced config option "ProactiveDRS" to 1, for any DRS cluster that you would like Proactive DRS to run on.
