RAID 10, 1+0, 0+1
I've reformatted and reset my readynas 600a to factory defaults with the intention of repurposing it. For my new purpose performance is more important than capacity, so I was trying to figure out if I could do a raid 10 or 1+0 configuration (instead of my previous raid 5) with this device just to get more spindles working on each read request and less I/Os per write: essentially a mirror of two stripes, or a stripe across two mirrors, whichever way you want to slice it.
I have 4 x 250GB drives in this machine, and if I choose RAID 1 to create a new volume, the maximum size I can pick is roughly 250GB, so i assume it won't by default stripe across more disks to give me what I'm looking for. Is there a way to pull this off with this device? If not, could you give me a rough idea of how X-RAID compares performance-wise to RAID 10.
Thanks,
Paul

- Can't do RAID-10 on Sparc devices. X-RAID is RAID-4.
- what about 1+0? Could I simply stripe across two mirrors? I mean, i'm pretty sure the md commands will allow me to do this, but how will frontview react? Has anyone else tried creating their own raid/lvm scheme inside a readynas?
