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.
