iSCSI Plugfest (Feb ) UNH InterOperability Laboratory Login Conformance Test Package (D8 & D9) - Test Suite - Scripts - Testor Interop test procedure Reference implementation - Initiator (D8 & D9) - Target (D8 & D9) Protocol Analyzer (D8) Overview of testing

iSCSI Plugfest (Feb ) UNH InterOperability Laboratory Issues Discovered Issue 1: Should the value of the Desired Data Transfer Length in an R2T be limited to MaxBurstSize? - Discussion on the CMU mailing list. - Clarified that MaxBurstSize does indeed limit the amount of data an R2T can request.

iSCSI Plugfest (Feb ) UNH InterOperability Laboratory Issues Discovered Issue 2: What should be done when SCSI-1 and SCSI-2 systems try to use iSCSI (which is based on SCSI-3). - Discussion on the CMU mailing list. - Conclusion: “Will not say anything about it in iSCSI Standard.”

iSCSI Plugfest (Feb ) UNH InterOperability Laboratory Features Summary Many implementations: - supported discovery sessions - supported parameter renegotiation during FFP Few implementations: - supported digests - dealt with multiple connections in a single session - allowed unsolicited and/or immediate data - supported portal groups - supported Target and Initiator alias - supported multiple outstanding R2Ts

iSCSI Plugfest (Feb ) UNH InterOperability Laboratory Features Summary (continued) Only 2 implementations: - had security code - supported persistent reservations - supported out of order PDUs within a sequence Only 1 implementation: - supported out of order R2Ts - supported additional header segments

iSCSI Plugfest (Feb ) UNH InterOperability Laboratory Features Summary (continued) No one: - dealt with Markers - dealt with bidirectional operations - dealt with Error recovery above level 0

iSCSI Plugfest (Feb ) UNH InterOperability Laboratory Summary Areas Not Tested: - Security - Error Recovery above level 0 - Digests - Multiple device interop - Markers - Naming and Discovery - Portal Groups - Additional Header Segment - Out of order PDUs and R2Ts More Testing needs to be done in: - MultiConnections in a Session - Discovery Sessions - Multiple Outstanding R2Ts - Parameter renegotiation during FFP

iSCSI Plugfest (Feb ) UNH InterOperability Laboratory Proposed items for the next iSCSI Plugfest - Error recovery above level 0 - Full Feature conformance - Digests - More testing in Discovery session - Security - Multiple Connections in single session - Performance measurement test suite - Testing of changes caused by drafts 10 and 11
