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
The Problem

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

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

Tunneled Over FC Storage
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

FAST Benefits
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

FAST Benefits
Improves SATA for enterprise applications SATA truly becomes multi-initiator, not multi-connected
Provides choice of SATA system interfacesSATA drives presented as SCSI
Deployment without major changes to RAID code baseAll translations confined within the RAID controllerNew storage features can be used without changes to the shelvesUses T10 specified SCSI/ATA translation
SATA drives presented as ATANo translation of commands
No need to mask errors in SCSI
