Well, if the server attached to the J series is doing ZFS/NFS,
performance will increase with zfs:zfs_nocacheflush=1. But, without
battery-backed NVRAM, this really isn't "safe". So, for this usage case,
unless the server has battery-backed NVRAM, I don't see how

Correct, and Live Upgrade also clones the active BE when you do

Why even both with a H/W RAID array when you won't use the H/W RAID?
Better to find a decent SAS/FC JBOD with cache. Would definitely be
cheaper.

Unfortunately, no inexpensive
cards exist for the common consumer (with ECC memory anyways). If you
convince http://www.micromemory.com/ to sell you one, let us know :)
Set "set zfs:zil_disable = 1" in /etc/system to gauge the type of
improvement you can expect. Don't use this in p
behavior? It really makes

FMA For ZFS Phase 2 (PSARC/2007/283) was integrated in b68:

it works for earlier builds, too.

AFAIK the write cache is always enabled for PATA drives:

ZFS root and boot work fine since the later snv_6x builds, the installer
is a different matter. You'll have to install to UFS and move to ZFS
http://mail.opensolaris.org/pipermail/storage-discuss/2007-July/003080.html
You'll need to determine the performance impact of removing NVRAM from
your data LUNs. Don't blindly do it.

How did you get NVRAM log devices?

f exporting is not possible, 'zpool import -f' will ignore that warning
and allow importing anyway.

Huh? So your MM-5425CN doesn't fit into a PCI slot?
