If you are using a virtual machine, you must be familiar with VMware DRS. VMware DRS is a tool that allows you to virtualize your computing needs and take all the advantage the virtual environment provides. Besides High Availability (HA), Distributed Resource Scheduler (DRS) is another great feature you can get out of a virtual machine. Now, let’s find out more regarding DRS and how you can use it.
What are the Benefits of VMware DRS?
The main benefit of VMware DRS is for load balancing. This tool will share the load of your computer with the virtual environment. You can set the DRS to recommend how many workloads to virtualize, or you can just set it to move automatically. No matter which option you choose, VMware DRS will make sure that your computer can run well with the workload allocation.
VMware DRS is the tool you want to use if you’re going to save up some budget. Since you can share the workload to the virtual environment, you can turn off some of your physical servers and let the virtual machine do all the work. Not only it can cut down electricity cost, but using VMware DRS also will reduce the high cost of cooling equipment since you can turn off the physical server without sacrificing any workload.
You can also enjoy the power management feature of this tool. It comes with Distributed Power Management (DPM), and it has more than one ESXi hosts available. As a result, there will always a backup just in case the hosts you are currently using is not enough to handle the workload.
How to Use VMware DRS?
Now, let’s find out how to operate this tool.
- Once you run the program, take a look at the list of the cluster names on the left side of the screen. Right click on the cluster name that you want to choose click Edit Settings and then check the Turn on vSphere DRS.
- After that, you need to choose the level of automation. It will determine how you want to share the workload of your server to the virtual environment. There are three levels of automation available: Manual, Partially Automated and Fully Automated. Here are the differences between the three of them.
This option will allow you to fully decide how many workloads you want to share with the virtual environment. DRS will provide some suggestions on the best load balancing as well as notifying you when resources start running low. However, you will be the one determining whether actions need to be taken or not.
If you choose this option, the system will automatically put a recently turned on a virtual machine in a host with the best capacity. However, if you use the tool normally, DRS will not make any action without your consent. You will be given options on which VMS that will work better if migrated, and then you can review them and only virtualize anything that you have chosen.
If this option is chosen, the DRS will migrate the VMS automatically everytime the system thinks it is necessary.
