Re: batterh backed cache forRAID controller
Thanks for the link, so you reckon if I update the drivers, that should make any difference ??
What else can I do to improve the HDD performance ???

Re: batterh backed cache forRAID controller
what about when you copy files between controllers? or between logical drivers same results?
I ask this since I am not database expert so I really did not get this "we load files to the db from flat files"...

Re: batterh backed cache forRAID controller
i don't understand what are you talking about.
First, you must better to explain mentioned situation.
If you have DB maybe problem isn't in logical drives. Maybe you don't have enough physical memory?
Kind regards

Re: batterh backed cache forRAID controller
Maybe I shoudl explain. We have Oracel 10.2.0.4 db which reads large flat files and loads data into a temporary table and then does some aggregation of the data and then loads them to another table.
I have 4G of RAM and have allocated about 4.5 to the db and have about 1.7G free for the server.
The db does not show much load but when the flat files are read and loaded to the db, the HDD are taking a lot of hit.
I hope this makes it a bit clear on what I wanted to say.
