Re: Single vs. dual shelf performance on F230

If you don't run noatime, you'll generate significant writes, depending on access type as I recall, and there's other things going on...

I'm still going to run with "not significantly faster". :)

Since the toaster only uses 1 parity disk for a whole pool of drives, I'm going to bet it's not significantly faster.

For writing perhaps, but disk reads don't touch the parity drive.

I'm going on the assumption that two controllers can queue up more commands than one. I suppose having a lot of read/write cache will mask most of the benefit of splitting drives across controllers though. -- Brian Tao (BT300, taob@netcom.ca) "Though this be madness, yet there is method in't"
