I am surprised that separating them onto different buses has so little effect. It looks like most of the bottleneck for large reads off two drives is not the IDE bus, but something else (maybe CPU or memory bandwidth). I was surprised too. Especially as it's an ATA-66 bus (the bus was expected to be a bottleneck). Only a single CPU. I would like to do more research on this matter and write a magazine article (I already have a magazine wanting to publish it). All I need is suitable access to the latest hardware to perform my tests (tests on old hardware while still being interesting research doesn't sell magazines). -- http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/projects.html Projects I am working on http://www.coker.com.au/~russell/ My home page

I would say that WAFL is an absolutely superb filesystem for the purpose of RAID NFS fileserving. Reiser4 may give it some serious competition after some time has passed and we have time for such things as carefully benchmarking NFS, etc., but WAFL is a great filesystem for NFS RAID as it is right now. That said, mp3.com saved $22 million dollars by using Linux+reiserfs instead of Netapps and Veritas. They may be good, but reiser3 is cheaper. A lot cheaper. Do the math, and you'll buy Linux instead I think.;-) Nobody has done reiser3 vs. WAFL benchmarks. Netapp as well have tons of features that linux boxes +PV210S can't do :Clustering volume copy, out out the box snapshots,etc.. Linux has snapshots if you use lvm, but it is true that Netapp makes a good product. | | Any comments on this setup is welcomed Now i think DELL realease their 220S with 14 disks in a shelf so that would have the bang for your bucks.

Hi, Yes, that's what i meant by not *out of the box* snapshots. We quite never played with LVM as it adds another software layer and i didn't feel it was mature enough at the time we put everything in production but given the benefits we might want to give it a try. BTW, Hans, what you would recommand : LVM or EVMS ?
