vSphere7 U2 new feature "Suspend to memory"

[baber]

As I see one of the new vSphere7 u2 feature is suspend to memory it is an excellent feature. Does it work such as follow :

 for example I have 10vm with 10G memory (Total 100GB memory is using) now if I select this option due to quick boot
instead of migrate 10 vms will be suspend them to esxi host and we have just a short down time according to boot time esxi and after
boot esxi, vms will be automatically resume their process
Is that ok ?

Yes, that is how the feature works. The host has to support quickboot for this to be available. The suspend / resume time is also affected by the amount of VM memory / memory speed etc., we recommend you test the approximate time for the whole process with a similar workload before using it in production.
