iSCSi Immediate Data Option
Hi Guys,
We have been having some iSCSI replication issues, basically the speed has been really slow. But after working with Dell on the issue we enabled the Immediate Data feature and the speed shot right up.
I have been reading up on the feature, but cant seem to find a simple concise definition of what it actually does.
The idea I get is that it basically just forces data down the link, without waiting for a response?

Pointed me to what I was looking for, I had trouble finding any concise info on it myself
This is often the issue, that hardware hba's do not support Jumbo Frames.
In tests software hba and jumbo frames, performs better than hardware hba's without jumbo frames.
