[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: iSCSI: Session Partial ResolutionDavid, If we eliminate all support for multiple connections from the next version of the draft and have a separate draft for multiple connections, then we'll eventually end up with 2 different (incompatible) protocols. Depending on whether we have a single connection or multiple connections, the initiator and target will have to implement one or the other or both protocols. Some products that implement only one version will not be compatible with other products, etc, and we will have shot ourselves in the foot. The wide acceptance of iSCSI will be strongly influenced by the ability to inter-operate with all kinds of devices and products, many of which will greatly benefit from one of the various multiple-connection models. I recommend to try to focus on the question of the multiple-connection model to see if we can at least agree that one or more of them sufficiently satisfies the requirements, and then choose one of the satisfactory models. Even if we can't agree on which model is the best, I think we can more-or-less agree on which of the models is at least good enough. - Kalman Meth Black_David@emc.com on 19/09/2000 22:22:20 Please respond to Black_David@emc.com To: John Hufferd/San Jose/IBM@IBMUS, Black_David@emc.com cc: ips@ece.cmu.edu (bcc: Kalman Meth/Haifa/IBM) Subject: iSCSI: Session Partial Resolution <... deleted ...> OTOH, I do not see consensus on the session model for multiple connection sessions among the Asymmetric model, the Symmetric model, and Pierre Labat's proposal. In order to make progress on iSCSI, I see no alternative to separating multi-connection sessions from the main iSCSI spec. Significant effort and email traffic has been invested in this topic for at least 6 weeks and the issue is not settled -- I don't think holding up the iSCSI spec for another 6+ weeks in hopes of settling this issue on the list is an effective way to make progress, but I'm prepared to listen to dissenting opinions (e.g., if someone thinks there is rough consensus, and I've missed it); please send such opinions directly to me rather than using the list. I've already had one offline comment from an outside observer expressing amazement at the willingness of this community to discuss multi-connection sessions "ad nauseum". Therefore, I would ask that the authors of the next version of the iSCSI draft delete all specification of multiple connection sessions from the next version of the except for a note that they will be handled in a separate document. <... deleted ...> --David --------------------------------------------------- David L.
