I'm just curious what others are doing or thinking in these terms.
Let's say you have a server with (3) 36GB SCSI drives and a RAID controller card.
Let's say you set it to a simple RAID 5 array.
Now comes the question and thought:
Once this is set, regardless of the logical drives and partitions I create, it's still going to access the entire array for read/writes, correct?
I mean, a D: drive for data isn't going to do much good if it's still on the same RAID array, right? Other than maybe saneness on my part from a management aspect.
I guess I always found it funny that MS and others would recommend things like the Pagefile on separate disks, Exchange logs on separate disks, etc. That to me would mean that you would need multiple array controller cards, and multiple arrays on each card, with quite a few physical disks, just to actually get separate disk I/O to happen.
Again, I'm not needing an answer to a problem...just curiousity as to whether my theory is right, and what others do. I'll split the points based on decent comments.
