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.

Reading the MD features I noticed there are several possibilities to create a mirror. I was wondering which one offer the best perfomances and/or what are the compromises to accept between the different solutions. One possibility is a classic RAID-1 mirror. Another is a RAID-10 far. There would also be the RAID-10 near, but I guess this is equivalent to RAID-1. Any suggestion on which method offers higher "speed"? Or there are other possibilities with 2 HDs (keeping the redundancy, of course)? Thanks a lot in advance, bye, -- piergiorgio -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
