See here: http://en.wikipedia.org/wiki/Nested_RAID_levels#RAID_10_.28RAID_1.2B0.29 or here: http://en.wikipedia.org/wiki/Non-standard_RAID_levels#Linux_MD_RAID_10> > -- > Kind Regards > Rudi Ahlers > CEO, SoftDux Hosting > Web: http://www.SoftDux.com > Office: 087 805 9573 > Cell: 082 554 7532 > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos

I am using it on CentOS 5.3 and it works really well. You might be interested in this article: "Why is RAID 1+0 better than RAID 0+1?" http://aput.net/~jheiss/raid10/

I found > a lot of RAID 10 setup instructions, but it doesn't help me. >Hi, what is your purpose with this Level? I'm asking because I had done some raid level tests some time ago with hardware raid controllers/systems from 3ware, sun and iscsi-raidsystems and some softwareraid setups. I haven't seen significant performance differences using different levels. (I'm not comparing the controllers.) Regards, G?tz
