<p> It is a a Dell 8024F. It has 24 SPF+ 10GbE ports and every NICs we connect to it are Intel X520. One issue we do have with it is when we turn jumbo frames on, the linux boxes crashes. So all our tests are done without jumbo frames, but that alone cannot make that much of a difference. We know the hardware of the Nexenta box can do several times better- it does when we run Linux on it. > What happens when Windows is the iSCSI initiator > connecting to an iSCSI > target on ZFS?

We did try two versions of Linux (RedHat and SuSE) and ended up with the same problem, but we haven't tried with Windows/Mac yet. Thanks all!
