New Fields in Discovery Responses John L. Hufferd
Questions • Value of having a connection type in the discovery response • Value of having speed indicator (perhaps relative) in the discovery response • Some have said this would be valuable • Value of having a preference indicator • Perhaps instead of a speed indicator • Some have said that this is useful even with speed value
Possible Syntax Examples • Target Name, IP:Port[, PGN[,Type[,Speed[, Preference]]]] • PGN- Portal Group Number (in RFC3720) • Type – 0- nn {IANA registered values} • 0 = iSCSI • 1 = iWARP • 2 = IB • 3 = … • Speed – 1x, 2x, 4x, etc • Preference – 0 – n {Higher value is higher preference}
Compatibility • Need to come up with a method for being compatible with previous implementations • Perhaps a new field in the Request • SendTargets command with new filed • Example: SendTargets <iSCSI-target-name>[,TSP] • Where TSP stands for Type, Speed, Preference
