It may be worth pointing out that I don't necessarily discount the "software" approach to storage management. If I've got a workload that is CPU-bound, and it is being dragged down by I/O wait due to storage management being done "in software", I've got two options: Buy dedicated storage controllers, or buy more general-purpose cores. The GP cores may well be the more effective route. In addition to often being cheaper, scaling better, and distributing better, I can use GP cores for other things when I/O isn't an issue. -- Ben _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
