VMWARE VSS running at once vs Nimble Snap

[szwicker]

I'm building new jobs where the source is a Nimble All Flash array so we have the benefit of backing up right from a Nimble snap.
When I create the jobs, I've been using the datastore as the selection to make sure I catch every single VM put on that store and so the Nimble only needs to create a single snap to cover them all.
So that's some 20 VMs (some big) running vsphere snapshots all at once.

Can that be an issue? Should I break them up so not so many VMs create snapshots or am I worrying for nothing?
