Hi,
Thanks for getting back to me,
Not sure if CBT is explictly enabled, howevrer I am using VDp so I would assume that's a yes.
Backend is a LSI 9260-8i, datastores are all running on 2TB RAID1 pairs.
I have not noticed any adverse effects, only the frequency of the messages made me take note, one every couple of seconds or so (does not seem to be related to when backups are running or snapshots beeing taken)
Cheers
