Re: iSCSI: SNACK R2T/Data

There is no ACK mechanism. The group wisdom was that there is no need for
one.
Incoming data and R2Ts are not acked (a mechanism that did that existed and
was based on NOP-Out).

Subject:  iSCSI: SNACK R2T/Data



Old subject, but I couldn't find any discussion on this:

When does the target know it no longer needs to hold R2T & Data PDUs?
StatSN responses are acknowledged through the ExpStatSN field received in
future I->T requests.  What's the acknowledgement method for R2T & Data
PDUs?  Is it tied to the original request and acknowledged through the
ExpStatSN acknowledgment of the request's response?

Thanks.
