[Q] Time to complete Quota recalc for 10000-UserQuota on a single filesytem

IHAC who puchased new VNX5600 and plans User quota recalcuration on a 4TB filesytem after replication migration from old NS120. There're 10,000 user quotas in the file system.

They know recent VNX File OE provides online quota calcuration by "nas_quotas -check -start xx". Practically they're hoping to estimate whole duration to complete so that they can arrange their change control plan more accurately.

I'm looking if someone has field experience about the following points for their reference.

1) Num of user/group quota in the fie system

2) File system capacity

3) Whole time to complete user/group quota calcuration by "nas_quotas -check -start xx"

Cheers!!
