Wow. an A1000. Ancient, but probably still OK. I'm not sure if there are any management utilities for them that'll run under Linux - I've only ever seen 2 of these and they seem to be able to run RAID themselves - might be faster, but the ones I had were slow anyway - maybe you can re-configure them to just look like 12 disks and let Linux do the RAID on them... Heres my suggestion: Install a 2.6 kernel. Partition both internal disks identically, then then combine all the partitions with RAID-1. Boot off RAID-1, if you can - I'm not up on the SLILO/whatever boot loaders for Sparc though. Configure the 12 external disks using RAID-6. You'll get one disk more worth of storage that way and still be able to sustain a 2 disk failure.
