Hi, thanks for the answer. Well what I would like to have is exactly a configuration hint, eventually benchmarks and the like. The requirements are: two disks, redundacy. The question is: what configuration is reccommended in view of performances (or "what can be achieved"). Is that specific enough? Thanks again, bye, pg On Sat, Jan 17, 2009 at 12:11:00PM -0600, David Lethe wrote: > All we know is that you use 2 disks and md. This is like posting to a TCP/IP architecture group and saying you have a network connection and want performance advice. Read up, supply full config info, run benchmarks, then ask specific questions.
