Another question: all those disks are on Dell MD1000 JBODs (11 of them) and we
have 12 SAS ports on three LSI 9200-16e HBAs. Is there any point connecting
each JBOD on a separate port or is it ok cascading them in groups of three? Is
there a bandwidth limit we'll be hitting doing that?

The answer really depends on what you want to do with
pool(s). You'll
have to provide more information.
Get the maximum of very random IOPS I get can out of those drives for database
usage.

Random IOPS won't max

My plan is to mirror all these drives and keep some hot spares.
