  3. The Problem • Tiered storage systems are becoming the enterprise standard • Performance tier is predominantly Fibre Channel / SCSI • Nearline tier has chosen SATA • SATA and Fibre Channel disk drives are not easily integrated into Fibre Channel based enterprise storage systems • Costly to replace and/or re-architect existing FC systems • Requires multiple skill sets to maintain • Impacts reliability with additional bridges and components The Solution • Integrate low cost SATA storage into existing Fibre Channel enterprise storage systems by… • Leveraging the universal transport nature of Fibre Channel to… • Encapsulate SATA FIS as a standard FC payload and tunnel it over FC infrastructure

  4. Fibre Channel. . . IT’S NOT JUST FOR SCSI ANYMORE!

  5. What is FAST? • Fibre Channel Attached SATA Tunnel • Encapsulates SATA FIS as standard FC payload • Attaches SATA drive shelves via FC infrastructure • Integrates SATA drives with enterprise FCP/SCSI storage in a single infrastructure. • Provides the same function as SAS/STP • BUT • allows true multi-initiator usage of drives • uses the mature FC infrastructure technology

  6. Legacy FCP Based Storage Tunneled SATA and Passthru FCP FAST Based Storage SATA Tunneled Over FC Storage FCP/SCSI Drives SATA Drives SATA and FCP Drives FASTEcosystem & Function • Connects SCSI/FCP drive shelves and SATA drive shelves through the same FC infrastructure • Encapsulates requests to SATA drives as FC-4 payloads and routes them through FC infrastructure • Routes requests to SCSI drives using standard FCP • Supports redundant connections to single ported SATA drives • Delivers true multi-initiator usage of SATA drives Existing FC IOC with firmware enhancements Existing Fibre Channel Infrastructure Enclosures with Fibre Channel AND / OR SATA Drives

  10. FASTBenefits • Protects investments by • Leveraging existing FC infrastructure • Lowers cost • versus FC capacity optimized drive approaches • versus bridge based approaches for FC to SATA conversion • Decreases time to market by • Leveraging existing FC infrastructure • Leveraging existing drive technology for all tiers • SCSI and/or SATA storage all with one interconnect • Leverages field proven Fibre Channel interconnect • Stability • Efficiencies • Scalability • Reliability

  11. FASTBenefits • Improves SATA for enterprise applications • SATA truly becomes multi-initiator, not multi-connected • Provides choice of SATA system interfaces • SATA drives presented as SCSI • Deployment without major changes to RAID code base • All translations confined within the RAID controller • New storage features can be used without changes to the shelves • Uses T10 specified SCSI/ATA translation • SATA drives presented as ATA • No translation of commands • No need to mask errors in SCSI

  12. FAST Next Steps • Create a standard! • Review concept with T13 (April 2005) • Conference Call to review Project Proposal (Early May 2005) • Approve T11 Project Proposal (June 2005)
