Re: PDU size for FFP negotiations

Eddy,

5.1 and 12.12 are not Login specific.
During Login you have a default MaxRecvPDUsize.

5.1 refers to a negotiating sequence (that may include several PDU's) and 
does no refer to the "primary buffers".
12.12 just advises you not to exceed the receive buffers.

In practical terms 5.1 should only set a lower limit to what a responder 
has to be able to accumulate if either the originator does not let him or 
he choose not respond to immediately.

Regards,
Julo

PDU size for FFP negotiations






I just want to be sure I understand the spec properly:
 
5.1 says:
 
Any iSCSI target or initiator MUST support receiving at least 8192
bytes of key=value data in a negotiation sequence.
 
12.12 says:
 
The transmitter (initiator or target) is required to send PDUs with
a data segment that does not exceed MaxRecvDataSegmentLength of the
receiver.
 
Note that 5.1 is not Login specific and since a "negotiation sequence" can 
occur in Full Feature Phase, then I am assuming 12.12 overrides 5.1 for 
Full Feature Phase.
 
Is that correct?
