[OpenIndiana-discuss] OI 151_a7 crashing when trying to import ZFS pool

[wim at vandenberge.us]

I'd go with an HBA and present ZFS with the raw disks. Save yourself a couple of
bucks and a bunch of potential hassle. I've had good luck with the LSI 9200-82
(external) and 9210-8i (internal). Both are PCIe 2.0. The 9207-8i and 9207-8e
are the PCIe-3.0 equivalents but I have not tested them. 85 drives is not a
problem on any of these.
