Best practice in Solaris 10 U8 and older was to use a mirrored ZIL.
With the ability to remove slog devices in Solaris 10 U9, we're
thinking we may get more bang for our buck to use two slog devices for
improved IOPS performance instead of needing the redundancy so much.
Any thoughts on this?

Ok, I'll bite.

video warehousing is a reasonable use case that will have small
numbers of sequential readers and writers to large files. virtual
tape library is another obviously

Hmm, SXCE snv_130 here. Did you have to do any server-side tuning
(e.g., allowing remote connections), or did it just work out of the
box? I know that Sendmail needs some gentle persuasion to accept
remote connections out of the box;
What are the ramifications to changing the recordsize of a zfs filesystem that
already has data on it?
I want to tune down the recordsize to speed up very small reads to a size that
is more in line with the read size. can I do this on a filestystem that has
data already on it and how does it ef

We have the following setup configured. The drives are running on a couple PAC
PS-5404s. Since these units do not support JBOD, we have configured each
individual drive as a RAID0 and shared out all 48 RAID0’s per box. This is
connected to the solaris box through a dual port 4G Emulex fibrechan

Excellent; what OS is your NFS server running?

My understand of the read cache is that L2ARC has a read thread to read the
cache from ARC. Hence my question.
if primarycache is set to 'metadata', will L2ARC get to cache user data?
similarly, what if primarycache is set to none.
Thanks,
