What are two features of storage DRS?

When you enable Storage DRS, you enable the following functions.

  • Space load balancing among datastores within a datastore cluster.
  • I/O load balancing among datastores within a datastore cluster.
  • Initial placement for virtual disks based on space and I/O workload.

What are the available options of vSphere DRS?

DRS has three levels of automation: Fully Automated – DRS applies both initial placement and load balancing recommendations automatically. Partially Automated – DRS applies recommendations only for initial placement. Manual – You must apply both initial placement and load balancing recommendations.

How do I change DRS settings in VMware?

Click “Manage” tab. Click “vSphere HA” Click “Edit button” on the right side. Click “Datastore Heartbeating”…How to disable Datastore Heartbeating

  3. Click “Datastore Heartbeating”
  4. Click “Select only from my preferred datastores”
  5. Do not select any datastores.

Does VMware DRS require shared storage?

CPUs in ESXi hosts must be compatible. to use DRS for load balancing, hosts in the DRS cluster must be part of a vMotion migration network. all hosts should use shared storage, with volumes accessible by all hosts. shared storage needs to be large enough to store all virtual disks for the VM.

Will Drs work if vCenter is down?

As DRS relies on vMotion/Storage vMotion and vCenter calculates a correct balance – DRS does not work when vCenter is down.

Which automation level is in a storage DRS Datastore cluster?

Manual
Manual is the default automation level. Placement and migration recommendations are displayed, but do not run until you manually apply the recommendation.

How do I manually run Storage DRS?

Procedure
