CPUs must be from the same vendor.

EVC must use the lowest possible baseline supported by the hardware.

CPUs must be in the same family and of the same speed.

No VMs may be running in the cluster.

Better performance because there is less contention for a single volume.

More flexibility for resizing virtual disks.

Less wasted storage space.

When there is more than one VM-Host affinity rule in a vSphere DRS cluster, the rules are applied equally.

After creating a VM-Host affinity rule, its ability to function in relation to other rules is predetermined.

When there is more than one VM-Host affinity rule in a vSphere DRS cluster, the rules will be ranked.

After creating a VM-Host affinity rule, its ability to function in relation to other rules is not checked.

Use Storage vMotion to migrate the Secondary VM to another datastore.

Use vMotion to migrate the Secondary VM to a different ESXi host.

Configure a CPU limit on the Primary VM which will also apply to the Secondary VM.

Turn off and turn on FT in order to recreate the Secondary VM on a different datastore.

Hosts with both 512e and 512n devices.

Storage vMotion between both 512e and 512n devices.

Datastore Extents spanned between both 512e and 512n devices.

Storage DRS clusters containing only both 512e and 512n devices.

Assign shares and limits to VM virtual disks.

Assign shares and limits to datastores.

Assign shares and limits to Storage DRS clusters.

Assign shares and limits using VM storage policies.

Storage latency is too high to allow Storage DRS initiate Storage vMotion.

Storage DRS is configured for a VMFS3 datastore.

Storage DRS is disabled on the virtual disk.

Rules prevent Storage DRS from making migration recommendations.

Disconnect ESXi host from vCenter.

VMware Tools are installed in the virtual machine.

Ensure that the system hardware complies with ESXi requirements.

Back up the host.

Check the interoperability of any other software integrated with vSphere.
