Of course, this will cost you more CPU.
No, in this case (fakeraid vs software raid) they both consume CPU, so I thoose the fastest and most stable, witch is kernel sw raid. -- Ariën Huisken Xilay Software _______________________________________________ tsl-discuss mailing list [email protected] http://lists.trustix.org/mailman/listinfo/tsl-discuss
