This should make login swift. Julo Santosh Rao <santoshr@cup.hp.com> Sent by: santoshr@cup.hp.com 24-10-01 20:04 Please respond to Santosh Rao To: Julian Satran/Haifa/IBM@IBMIL cc: ips@ece.cmu.edu Subject: Re: iSCSI minimum PDU length Julian, Does the below imply that the length retriction of 4K on text & nop operations is also removed and we now need to handle multi-sequence nop operations ? I suggest that maximum nop operation length be restricted to the minimum PDU length that the draft will require. This will avoid adding multi-pdu sequence complexity for the nop-out/nop-in pdu's. The current login & text pdu's do allow for multi-sequence operations based on the T/F bit. This should be sufficient if the login/text payload exceeds 1K , as long as "key=value" operations are not going to span pdu's. Is that correct ? - Santosh Julian Satran wrote: > > With no votes against we have settled (again) on single PDU length (per > connection, per direction) for all types of PDUs. > But I think we erred on the low side by suggesting 64 as a minimum.
