Hello,
I don't have any experience with ZFS when the disks are in external cabinets. I
have a few questions:
1. If I have a lot of spindles in an external cabinet, I'll have several disks
sharing channels (between 3 and 6 depending on chassis). I know this is

directory subtree full of raw camera images, about 15MB each, totalling
say 50GB) on a ZFS filesystem, and take daily snapshots of it (without
altering it), the snapshots use almost no extra space, I know.

On some machines running PowerPath, there's sometimes issues after an
update/upgrade of the PowerPath software. Sometimes the pseudo devices get
remapped and change names. ZFS appears to handle it OK, however sometimes it
