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
