Thanks for the tips. I'm not sure if they will be relevant, though. We don't
talk directly with the AMS1000. We are using a USP-VM to virtualize all of our
storage and we didn't have to add anything to the drv configuration files to
see the new disk (mpxio was already turned on). We are usin

I think we found the choke point. The silver lining is that it isn't the T2000
or ZFS. We think it is the new SAN, an Hitachi AMS1000, which has 7200RPM SATA
disks with the cache turned off. This system has a very small cache, and when
we did turn it on for one of the replacement LUNs we saw
It's something we've considered here as well.

We will be considering it in the new year, but that will not happen in time to

Have you considered moving to 10/08 ? ZFS resilver performance is
much improved in this release, and I suspect that code might help you.
You can easily test upgrading with Live Upgrade. I did the transition
using LU and was very happy with the results.
For example, I added a disk to a mirror an

In the process of a large SAN migration project we are moving many large
