1 Making Removable RAID Disk Media A Reality Changing the World of Storage RXT Applications from SMB to the Enterprise Spectra Logic Corp. – Boulder, CO

2 HDDs as Removable Media  HDDs have many inherent advantages: Performance (random access vs. sequential) Size Capacity Trends Cost Trends Interface Trends  However, new HDD applications have been limited by: Fixed Configurations (static arrays) as secondary use Differentiation between Enterprise and other applications Perceived “robustness” for removable use Lack of appropriate architecture/standard for portable use

3 What has Changed to Make Removable Disk Feasible Now?  Availability of Highly Reliable, High-Performance SATA Drives, particularly 2.5” FF for Mobile Use 900G Shock Protection (non-operating) 1,000K Hour MTBF 80GB per Spindle and moving to 100+ GB soon 80MB/sec Data Transfer Rate Simplified Serial Interface (SATA) with low Connection Count  Rugged, Innovative Packaging & Controller Architecture Unique, shock-protected packaging for HDDs as removable media Unique Docking Station/Controller provides power, I/O & Data Formatting  Embedded RAID Controller for high data integrity

4 Removable HDD Architecture – Putting the Pieces Together  Shock Mount Off-the-Shelf SATA HDDs in a Portable Enclosure  “TeraPack” Module  Controller to Accept TeraPack Modules & Provide RAID Data Protection  “Docking Station”  “RXT” Architecture

5 What Is RXT?

6 What is the Application Opportunity?  High-performance, high capacity, removable media for data protection, archiving and interchange. What are the Design Objectives for Portability?  Provide best reliability and data integrity  Provide a scalable architecture base  Integrate both disk and tape seamlessly  Provide multiple capacities and application configurations RXT Implementation

7 RXT Removable Disk Module (TeraPack)  Contains Up to 12 SATA HDDs shock mounted in a “TeraPack” enclosure  “Connector Array” provides interface for each HDD to the Docking Station No Power or Electronics contained in the TeraPack – Just HDDs  Bar Coded for Data Set Management (manual or automated)  Can be transported manually or through an automated library robotics environment

8 RXT Docking Station  RXT Docking Station/Control Unit – enclosure with opening to accept RXT TeraPack media, providing power, control and RAID functions Provides Ultra-SCSI 320 I/F to host system Contains processor running own OS to manage all functions, including RAID Contains “pogo-pin” array to connect to RXT media pack (provides power, I/O, etc. to each drive in TeraPack) 5.25” Internal or External packaging.

9 RXT Is True Removable RAID  Unlike a traditional HDD RAID configuration, RXT is a fully enclosed array of HDDs that can be removed as a RAID unit for: Offsite storage High speed data exchange “Near-Line” storage in library automation In a Traditional RAID Array, individual component disks are removable, but the array (and the data) is “fixed”

10 800GB RXT MediaRAID Levels 0 and 1 (2) 3.5” 400GB SATA Disk Drives  Lower Cost  Targeted at Mid- Range applications 960GB RXT MediaRAID Levels 0, 1, and 5 (12) 2.5’” 80GB SATA Disk Drives  High Performance  Best Shock Protection  Targeted at Enterprise applications RXT RAID Media Choices The RXT RAID TeraPack

11 RXT Media Evolution Current RXT Media options Configuration(2) 3 ½” SATA drives (12) 2 ½” SATA drives Capacity RAID Level 800 GB per TeraPack case 0, GB per TeraPack case 0, 1, 5 As SATA drives grow in capacity, cost effectiveness and performance, so will RXT media. 3 ½” media — greatest $/Terabyte value. 2 ½” media — highest throughput, capacity, data integrity and reliability

13  Traditional Data Protection and Archiving Fast, reliable back-up and restore  Move off-line data, on-line rapidly  Move off-site data to DR site for faster recovery Short-Term On-Line Archiving Complement Tape in automation applications  Vertical Markets Defense/Security – Rugged, portable media for transport & high-speed access Video Broadcast – High capacity, performance access of large data sets Oil & Gas - Rugged, portable media for transport and interchange Service Providers – Portable media for archive, fast restore RXT Target Markets

14 The RXT Configurations & Applications  RXT Standalone SMB Backups - environments too small for automation Disaster Recovery “Hot” Sites Media can be rotated exactly as tape High-performance removable storage for Vertical market applications Provides media interchange with automation applications RXT Standalone Docking Station & Media

15 RXT Configurations & Applications  RXT with Server Backup individual servers directly to removable RAID More reliable than tape auto- loaders. High-performance removable storage for Vertical market applications Server, RXT Docking Stations, & Media

16 RXT Configuration & Applications  RXT Rackmount 2U (3.5”) Rack-mountable unit 3 Devices, either RXT or Tape Drives Can be used independently, or in conjunction with the T120 tape library Simple device copy for D2D2T backups RXT Rackmount Docking Station & Media (Shown With Spectra T120 Library)

17  Tape/Disk Library Automation RXT Docking Stations and RXT Media are installed into existing drive bays and media storage chambers RXT Utilizes Existing Robotics, Interfaces, and Power Tape/Removable Disk can Co-exist in same library  Removable HDD capacity scales from 960 GB to 90TB/Cabinet Transparent to backup application Storage Chambers Drive Bays RXT in the Enterprise T950
