Communication Channels

• Utilize more efficient communication models
  between the two bodies
• T13 any new proposed definition that is Serial
  ATA related should be presented to the liaison
  for review by SATA-IO
• Including any identified areas of new definition
  that require SATA-IO specification changes should
  be brought to T13 for review through liaison
  prior to finalization of content
• SATA-IO any identified areas of new definition
  that require ATA/X specification changes (e.g.
  reservation of op codes, log pages, etc) should
  be brought to T13 for review through liaison
  prior to finalization of content
• T13 proposals and other material posted publicly
  through T13 website
• Availability of documentation to SATA-IO for
  review
• Ratified specifications are available publicly
  through SATA-IO website
• SATA-IO draft documentation is available to
  SATA-IO contributing members in the appropriate
  Work Groups

Pro-actively using both groups for review of
Serial ATA material assists in ensuring
consistency and lack of conflict

Key Concerns

• Ensuring consistency between published
  specifications containing Serial ATA material,
  specifically
• SATA-IO Serial ATA 1.0a specification, Serial
  ATA II specifications (Extensions to Serial ATA
  1.0a, Electrical - Phyii, CabCon Vol. 1 2, Port
  Multiplier, Port Selector)
• T13 ATA/7
• Need to avoid industry confusion and potential
  interoperability issues by driving consistency
  between the two sets of specifications
• Host controllers and devices have been designed
  productized around the initial SATA 1.0a
  specification for over two years. Specification
  is stable and mature.
• Any changes to definition of SATA behavior in
  ATA/X material which conflicts with existing SATA
  material could result in significant field issues
• Any changes to definition of SATA behavior in
  SATA-IO material which conflicts with existing
  ATA/X material could result in significant field
  issues
• Ensure that any newly created material in either
  forum does not directly conflict with existing
  Serial ATA specifications or ATA standards

Integration of 1.0a material into ATA/7 (and
possibly future docs) must not inhibit
interoperability of existing implementations
