Working toward a new Copyright Agreement between SATA-IO and T13 (T13/e09149r1)

The Issues The schedules for updating T13 and SATA-IO standards are not synchronized Currently there must be re-negotiation for a new agreement for every combination of T13 and SATA-IO revision T13 documents have been split into multiple pieces, so new copyright agreements are needed It would simplify matters for both groups if a broader agreement could be made, not tied to specific document revisions Section numbers often change between revisions, so tie the license to classes of content instead T13 Liaison to SATA-IO e09149r1 Nov. 4, 2009

Record of working together T13 and SATA-IO successfully negotiated copyright agreements for: SATA Revision 1.0a for ATA/ATAPI-7 SATA Revision 2.5 for ATA8-ACS SATA Revision 2.6 for ACS-2 T13 has primary responsibility for ATA commands and architecture that are defined for all device types (e.g. the Application layer) and for everything dealing with PATA SATA-IO has primary responsibility for SATA-only commands and all other interface layers (Phy, Link,Transport,Command) Many companies belong to both organizations T13 and SATA-IO have synchronized updates to the other group’s standards with their own T13 Liaison to SATA-IO e09149r1 Nov. 4, 2009

Record of working together Adding some SATA Revision 2.5 features to ATA8-ACS Adding new ATA8-ACS to SATA Revision 3.0 NCQ clarifications, READ LOG DMA EXT, device signature clarification, Write-Read-Verify, new IDENTIFY DEVICE and DCO features Adding SATA Revision 2.6 features to ACS-2 NCQ Priority and NCQ Unload, new SATA-only IDENTIFY DEVICE and DCO features T13 Liaison to SATA-IO e09149r1 Nov. 4, 2009

The Proposal A new agreement is needed by T13 to include some SATA Revision 3.0 material into ACS-3 Make the agreement not restricted to specific T13 standards, but for any T13 standard ATA8-AST and HBA-2 would benefit from improved access T13 is considering splitting ATAPI from ACS-3 Make the agreement reference content “classes” instead of specific document section numbers The industry often looks to T13 as the first place to look for command definitions, so T13 would like to have access to newer SATA-IO command information.
