Stefan, you should be able to simply clear the P410i configuration in the BIOS, power down, then simply connect the 6 drive backplane cable to the 410i, load the config from the disks, and go. This allows head to head RAID6 comparison between the P400 and P410i. No doubt the 410i will be quicker. This procedure will tell you how much quicker.Unfortunately, the server is located at a hosting facility at the opposite end of town, and I'd spend an entire day just traveling to and fro, so that's not currently an option. I might get lucky though, because we should soon get another server with an external P410i.
The new storage blade has only been upgraded to the P410i controller, and even though there is a new setting called "elevatorsort", which is enabled, the performance is just as bad. The new one has a flash-writeback cache and may be faster by a few percent ticks, but that's it. It doesn't even make sense to compare the two in-depth, as they perform almost identically. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
