This is relative. There are indeed situations where it's acceptable to
disable ZIL. To make your choice, you need to understand a few things...

Disabling the ZIL (Don't)
Caution: Disabling the ZIL on an NFS server can lead to client side corruption.
The ZFS pool integrity itself is not compromised by this tuning.
so especially with nfs i won`t disable it.

Edward,
I recently installed a 7410 cluster, which had added Fiber Channel HBAs.
I know the site also has Blade 6000s running VMware, but no idea if they
were planning to run fiber to those blades (or even had the option to do so).
But perhaps FC would be an option for you?

Hi,
we have the same issue, ESX(i) and Solaris on the Storage.
Link Aggregation does not work with ESX(i) (i tried a lot with that for
NFS), when you want to use more than one 1G connection you must
configure one network or vlan and min. one share for each connection.
But this is also limited

Would NFSv4 as cluster system over multiple boxes work?

Channeling Ethernet will not make it any faster. Each individual connection

1G Ether is so cheap, but not as fast as desired. 10G ether is fast enough,
but it's overkill and why is it so bloody expensive? Why is there
