Thanks everyone! We attached the shelf to a Linux host and are able to see all 14 disks. CentOS is detecting them oddly, so we're still working through the details. I'll report back with when we get this working!

I imagine you could do the reverse of this hack to change from the NTAP 520 byte format to 512 byte format:

I've never tried either, so your mileage may vary.

I tried to do something like this about two years ago with a SunBlade 100 running Solaris 10, maybe 9, and using ZFS. Never got it to work reliably for whatever reason, and gave up. I was probably using a DS14mk2 though, so who knows.
As I recall, the biggest issue was the 520 byte sectors the Netapp drives come with, instead of the expected 512 byte sectors that most drives use natively. I seem to recall there was a trick you could use to make it work, but the hardware is gone so I can look it up.
