Dan,
I'm not sure about that particular card, but we've never seen that great
of performance out of the LSI MegaRAID cards that ship with Dell servers
as the PERC. The newest incarnations are better, but I would try to get
an Areca. The ones we have tested have displayed fantastic
performance. They are fairly expensive in comparison, though. If
you're using ZFS in place of the RAID on the LSI MegaRAID, I'd instead
recommend other simpler SAS cards which are known to have good driver
support.
Yes, the card will be used as a straight-through and not use for RAID.
ZFS will be running raidz for me, possibly raidz2. Given that, I'm not
sure if you're suggesting the3 Areca or something else.
In addition, I'm not sure what makes a SAS card simpler and supported.
Recommendation?
Other cards I have considered include:
