hi,
I have a server with 3 x 500 gig drives. (It has only around 300gigs of data being used.)
currently only 2 drives are being used. 1drive is primary and the other is just backing up the data from the first drive. 3rd drive not really used or mounted at the moment.
I have been told the site is failing due to high disc io. There are 3 domains being used on there. The data is not critical and i have local backups.
I was wondering if it is possible on a server to allocate 1 domain to each of the 3 drives? so splitting the load over 3 drives, each domain is actually using rought the same BW.
Is this possible ? since the rest of the resourses like memory and cpu are not used much.
Would using raid be a better option ?and if so which raid to use for fastest speed and highest tolerance to disc io considering i have 3 drives and no real need of backups?
I have been told raid is going to cost quite a bit more so i am hoping to be able to just put 1 domain on each drive thus splitting the load that way if possible ,or if it will even be effective.
thanks
