Troubles with Oracle on NAS? Old Stuff Deployed?

In Vidya Bala’s Blog post about Oracle on NAS, there is evidence of past problems with this NAS storage under older Linux distributions (e.g., SLES8) and older Oracle releases (e.g., Oracle9i). Most folks know I am a staunch proponent of Oracle on NAS and have blogged about it here and here.The most important thing to remember is that a noac mount option is no substitute for open(,O_DIRECT,).

 

I’ve blogged that, in my opinion, the first production-quality stack for Oracle on NAS is Oracle10gR2 on 2.6 Kernel releases. However, I can’t speak from authority on the Legacy Unix capabilities in this space. I’ve got too much Linux around here.

    Our current site (Solaris 10, 10g Rac, NAS (NFS — NetApps)) does 675 executes/Second. This is amazingly big in comparrison to anything that I have seen with any other configuration before, ofcourse a properly tuned application playes a huge role, but beyond that NFS can pump megs of data/Second for the DB — Mount settings play a very important role, A ForceDirectIo in place of a Cached IO can make a difference of a Day and Night when it comes down to Oracle running server with NAS as a storage. Apartment from suitable performance, It also provides extreme ease of maintenance, by providing : Filer Snapshot (for taking quick backups) Clone volume (for creating DB clones), and FlexVols (Flexible data management).
