Re: Disk Groups for Oralce Database

Bonjour,

HP has probably recommended 2 DG for security reasons.

If you loose the datafile DG, you wil be able to restore accuratly with the LOGs.



As always, it depends ... What is your focus ? Security or performances ? For performance reasons, choose only one DG, for security reasons 2 DG is enough, even if you have 3 databases.

But don't forget that if you want to achieve the best level of security there are many others points you must take care of. For example yous must have at least 8 shielves in your EVA, redundant fabric paths, and so on ...

Regards
