re: Not if you look at what he has to work with. ~Umberto Nongeroson 2.May.03 01:31 PM a Web browser Domino Server All ReleasesLinux - RedHat
Hmmm.... you're right... I was thinking he had 7 potential drives for data alone. I guess that's what I get for starting a reply and coming back to it 4 hours later after working on some other stuff.
I'm re-reading his post, and he also says he will use one for a transaction log and one for view building (a very smart move, BTW). If you figure one more for OS/Executables/Swap/etc. then that's only 4 drives for data... 64 GB under RAID 1+0, 96GB under RAID 5.
It might definitely be a tight fit on RAID 1+0, but then again 64 GB might do him fine. Rainer, do you *also* need to keep one of those drives around as a spare?. In that case, a 3-disk RAID 5 configuration is your only option, which gives you 64GB for your data:
1 drive - OS/Executabes/swap
1 drive - Transaction log
1 drive - View building
1 drive - Spare
3 drives - data RAID 5, total of (2*32)=64GB storage
If 64GB isn't enough, another option might be moving the view building drive to your OS/Exec/Swap drive.
1 drive - OS/Executables/Swap/View building
1 drive - Transaction log
1 drive - Spare
4 drives - OS/Executables and data RAID 5, total of (3*32) = 96GB storage
This theoretically gives up a tiny bit of performance on the view-building, but if all that's running is Domino you shouldn't see much in the way of other I/O on that drive anyway if you've got sufficient RAM to keep swapping to a minimum. If that *is* the case and 64GB will work for your data, then using that configuration set up as RAID 1+0 would probably be your best route. With large DBs you'll want as data I/O as fast as you can. That would leave you with:
1 drive - OS/Executables/Swap/View building
1 drive - Transaction log
1 drive - Spare
4 drives - OS/Executables and data RAID 1+0, total of (2*32) = 64GB storage
Again, this only works if (a) you one of those 7 drives as a spare, (b) 64GB is enough for what your data, and (c) you've got enough RAM to keep swapping down (at least 2GB).
