Superiority of Fibre Channel TechnologyFast & Flexible Tiered Storage October 2005 Revision 2
Offline Online Nearline Information Lifecycle Management Requires Tiered Storage • The SNIA Data Management Forum (DMF) definition for ILM reads: • “Information Lifecycle Management is comprised of the policies, processes, practices and tools use to align the business value of information withthe most appropriate and cost effective IT infrastructure from the time information is conceived through its final disposition. Information is aligned with business processes through management of policies and service levels associated with applications, metadata, information and data.” Matching Data To Most Appropriate Storage Type Is The ILM Enabler ILM Tier Storage Tier Type Enterprise-Class HDDs High Performance & Reliability Nearline Optimized HDDs Nearline & Temporary Retention Tape Backup Long-Term Storage

Fibre Channel Is The Dominant Solution for External Storage Systems External Storage System Revenue By Drive Interface* Source: Gartner, September 2005 * External Storage means storage arrays only
SAS Is Emerging to Address Tiered Storage and Is Encroaching Fibre Channel’s Market • How SAS is Positioning Itself Against FC • New physical layer technology • SAS Primarily developed as a parallel SCSI drive replacement • Emergence in external storage is primarily to natively connect SATA drives for low cost • Marketed Benefits • Most addresses parallel SCSI weaknesses • Perceived system cost savings over current FC connected solutions • 2.5” SFF Disk Drive format • Physically connects SATA drives
Beginning of FC versus SAS ChartsStill a TBD, but I ran out of time.Slides are in work
Fibre Channel RoadmapFastest Interconnect Speeds Fibre Channel Speed Chart Base2* Base10** *Base2 used throughout all applications for Fibre Channel Infrastructure and devices. Each speed maintains backward compatibility at least two previous generations (I.e., 4GFC backward compatible to 2GFC and 1GFC) **Base10 commonly used for ISL, core connections, and other high speed applications demanding maximum bandwidth Lines Rate: All speeds are single-lane serial stream
