Gentlemen, I need your opinion on a creation I am about to unleash on our unsuspecting production site where I work.
I currently have a 740 filer with 2 shelves and 7 disks.
3 disks are in the first shelf and configured for volume 0 root volume 4 disks are inthe second shelf and configured for volume 1
Now, since I didn't put this box together. I was wondering if it is better to make all of these disks one volume. There are heavy reads and writes to the volume1, but I don't know if having a heavily used volume combined with root functions will kill my performance. Besides this will make a larger volume for more distributed writes (8 total disks versus 4). Also I will be saving 1 disk of data space because I won't need the second parity disk.
Addition information is that they are fibre channel shelves (of course). And that the data is not important (washed away daily).
Assuming that the root volume functions do not critically affect my box (and I don't believe that they do, as most of it is running from memory) I believe my choice is correct.
Just wondering if you guys agree with this hypothesis or not.
