Sata express-briefing-presentation final

  1. 1. Evolving SATA for High- Speed Storage August 2011 1
  2. 2. AgendaSATA in PC ApplicationsSATA EcosystemSpeed requirementsIntroducing SATA Express™– Technical overview– Benefits 2
  3. 3. SATA for PC Client StorageA Mature Interface – SATA is the de facto standard for PC storage; also widely implemented in mobile and enterprise applications. – Adoption of SATA 6Gb/s technology is strong 3
  4. 4. A Growing Ecosystem SATA implementations are becoming increasingly application specific. Since its introduction, SATA has evolved into new application spaces and now provides storage interface solutions for HDDs, ODDs, SSDs, and hybrid HDDs in client PC, mobile, enterprise, CE, and embedded storage markets . 4
  5. 5. Example Application-Specific ImplementationsmSATA (mobile applications)SATA µSSD (embeddedapplications)USM (consumer electronics, PCapplications) 5
  6. 6. Application Speed RequirementsToday, mostapplications are well-served by SATA 6Gb/sand will be for theforeseeable futureSSDs, however, willsoon require greaterspeeds than thoseenabled by the currentgeneration of SATA. 6
  7. 7. Introducing: SATA Express ™To meet speed requirements in SSD/hybrid drive applications,SATA-IO is developing SATA Express ™: – Combines SATA software infrastructure with the PCI Express® (PCIe®) interface – Defines new device and motherboard connectors to support both new SATA Express and current SATA devices – Provides 8Gb/s and 16Gb/s – Protects investments in both SATA and PCIe – Will coexist with other application-specific SATA formats 7
  8. 8. SATA Express: Connector Changes Desktop Connector Concept SATA Express Conn. Accept a x2 PCIe, or a x1 PCIe, or two SATA cablesAccept only a x2PCIe, or ax1 PCIe cable PCB PCIe Conn. PCB Keys that reject the SATA cables 8
  9. 9. SATA Express: Cable Changes Desktop Cables Concept SATA cost/performance benefits PCIe Cable Requires a connector that supports both PCIe and SATA Allows a single motherboard Existing SATA Cable (backplane) connector to support both interfaces HDD-compatible form factors to be defined for SATA Express devices Enables system-level mechanicalPCIe Cable compatibility Preserves high-capacity storage PCB SATA-IO CabCon is developing backward PCB SATA Express Conn compatible connectors and form factors for SATA Express devices PCIe Conn. 9
  10. 10. SATA Express BenefitsProvides a cost-effective solution for increasing deviceinterface speedSpecification can be completed and implemented relativelyquickly, since both SATA and PCIe are already widelyimplementedHelps ensure seamless coexistence between SATA and PCIe Protects developer investments in both interfaces 10
  11. 11. SATA-IO Roadmap SATA 3.2 • Includes SATA Express • µSSD SATA 3.1 • mSATA detect, zero power ODD • Required PM, CAP_ID, USM SATA 3.0 • 6Gb/s Internal • Isochronous NCQ cmd, NCQ mgmt cmd, LIF 1.8, 7mm ODD, ATA8 • Certified Logos SATA 2.6 SATA-IO Inc. • 3Gb/s Internal/External, NCQ unload, Slimline ODD connector, Four lane e/xSATA connector formed 2004 SATA 2.5Serial ATA WG • 3Gb/s Internal/Externalformed 2001 • eSATA, Click Connect, SSC, NCQ, Staggered spinup, ASN SATA 1.0 • 1.5Gb/s Internal/External • Port Multiplier, Port Multiplier, ATA6 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 11
  12. 12. Next Steps And TimelineSATA Express is currently under development withinthe SATA-IO Cable and Connector Work Group Completed specification expected by end of 2011In the meantime, SATA-IO will continue to optimizethe existing SATA infrastructure for a wide variety ofapplications SATA will continue to be the mainstream storage interface for the foreseeable future 12
