Lustre discuss - Dec 2010 - Optimal block size for database ...

Hi All,
       I am studying Lustre file system for optimal block size
for ldiskfs so as to get best performance out of Oracle database.
       What is the average size of files that Oracle database
access ?

Regards,
Onkar

Lustre only supports 4096-byte blocksize for ldiskfs, so that makes your study
very easy. I suspect that Oracle database uses 8192-byte blocks, but to be
honest I don''t know anything about it.

That said, Lustre is probably not very well suited for Oracle databases, but
I''d be very happy to see any results you can generate in this
configuration. Please post the results to this list.

Cheers, Andreas
