Hi,
I have a theory question on storage replication of a SQL server host system.
Is it a safe solution? I mean log disks and data disks are not syncronized together and I am not sure that each logical disk is consisted of only one LUN. Let's say that the log disk is synchronous and that only data disk(s) are behind in time.
What would happen when the instance tried to start? Would it be able to recover since log files have more recent transaction information than datafiles?
Or would the databases fail to recover and stay in suspect mode?
I would make sure that log disks and data disks are consistently replicated just to be sure, but I would like to understand this scenario.
Thank you in advance,
Marios
