[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] RE: iSCSI: Require iSCSI to use packet formats similar to FC, etc ??There are a number of things we have done with iSCSI, such as Multiple Connections per Session which are important that do not map to Fibre Channel. (Most of you can also call out things in iSCSI which are important to you, and different from FC). The important thing is to carry the semantic of SCSI, and cause as small as state as possible to be required in the Gateways. There are probably a number of folks on the reflector that are building Gateways, the most famous/infamous is CISCO. So when Mark said it was not an issue, that other items were lots more important, that locked the answer for me. We are near the end of this PDU format journey, and now that the OP Code issue is solve, we should be on the tail end of the process. Changing formats of PDUs should not be acceptable, now, unless something is broken. So I do not think it is important to add requirement words, that could distract us from finishing, which have not been needed up to now. We have bigger focus items now, like Naming, Discovery, Security, etc. we should focus on this items, and not on items which are non problems. . . . John L.

An independant protocol that is agnostic to the transport medium would probably be too general to be optimal in any specific transport environment. I think the solution is to make SCSI truely independant of the transport (strictly layered on top of the transport). It seems that T10 is realizing this and some are working towards that goal. IMHO, requiring that iSCSI match other transport formats is going at the problem from the wrong end. Marj
