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@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
