What is VMware DRS?
VMware DRS, recently released by VMware, provides soft load balancing on storage, and also allows you to optimize the load of virtual machines on disk devices without interrupting the VM.
In addition, the characteristics of the vaults at their initial location are simultaneously taken into account. VMware DRS can balance VMs between storages on input-output (I/O) and between storage spaces on their fullness.
There is also a function to reduce the number of errors when choosing a VM storage space and managing storage.
When do you need to use VMware DRS?
VMware DRS is usually used in medium and large virtual environments, when the load on each machine is not the same and varies throughout the day.
In this case, the main merit of this technology is ensuring the correct distribution of resources.
If it were not for the basic built-in functions of VMware DRS, then the load balancing operator would have to decide on the hosts of the virtual machines.
But it is clear that a single person cannot do this as effectively as mathematically calculated formulas.
How does VMware DRS work?
The VMware DRS dynamic load balancing mechanism is used to level the VMware ESXi host servers under uneven load conditions. This is due to the provision of timely and useful recommendations for migrating virtual machines using vMotion to other hosts. If desired, the administrator can configure the automatic implementation of these recommendations.
Quite often, DRS interacts with HA, and at the same time, failover occurs with load balancing; this is convenient and practical. Also remember, theoretically, the restriction on a cluster is 32 nodes, but it is better to use no more than 20-24, based on experience. The more hosts, the more DRS calculations, and the more resource consumption.
What are VMware DRS’s benefits?
The main advantage of DRS is primarily balancing the main load on the VM.
VMware DRS also provides distributed power management and compliance rules. Depending on the settings, the program will check and give recommendations after a certain time and, if necessary, execute these same recommendations in manual or automatic mode. In general, calculating the values of all variables and giving the correct answer is the work of machines, not a person, so you should trust and enjoy the work it does.
Perform VMDK recovery from VMware VM with VMFS Recovery
DiskInternals VMFS Recovery clearly reads the VMFS file system and then flawlessly restores files and folders from damaged and undamaged disks in VMFS format. All the work of the application occurs online without shutting down. There is a unique option to restore VMDK files stored on disks formatted using VMware ESX/ESXi Server. Virtual disks can be mounted as local disks, in which case they will be available in Windows Explorer.
Moreover, Windows restrictions can be bypassed during recovery. After downloading DiskInternals VMFS Recovery, you will see all the available functions; all this is free, and an application license is required only for exporting files to local or remote locations.
