John, Thank you for the quick response. I asked our DBAs why they chose ReFS over NTFS and they indicated that it was a Microsoft recommendation to overcome an issue they were having with a very large databse (VLDB) ... back then, it was 3.5TB ... The issues they were having were around performing database consistency checks (DBCCs) on the database. It is my understanding that the DBCCs would get a storage timeout and thus the DBCC would fail. I have asked my DBA's to forward me ther pertinent Microsoft information, as right now, I only have this rudimentary understanding of their original problem and the supposed Microsoft recommendation.
Today, what we are trying to use SnapCenter for, is to do backup management of a 13TB MS SQL database, as well as use it for CLONE features, so that we can create 1 or 2 FlexClones off of the source database snapshots.
We are also working with our DBA's to see if we can rebuild the volumes using NTFS, and hopefully not have the DBCC issues they were having before.
Once I gather more details around the Microsoft recommendation to go from NTFS to ReFS, I'll post a reply to this conversation.
