sorry I have not, that is the next logical step but only my esxi servers have 10g interfaces and I cannot take them down at the moment.

I have been looking this issue up online and I do find some people with poor reads and good writes. In some cases they are saying it was a mismatch in the target and initiators block size. can anyone assist me with figuring out what the zfs blocksize is.

Have you tried a native OI client yet?
