we got a 1TB Oracle 11g Database with RAID5 for data file storage.
Yes, I/O is our bottleneck but we have no chance to change the RAID.
We got one TBS wiht a size of 250GB and circa 60 files each 4GB in size.
Is there a gain, to have such a lot of files or does it not matter for I/O?
I would prefer to have only 5 files with 50GB in size.
It would be much easier to manage!
What would you prefer?
