4 In this session you will learn About a New Dynamic of storage for a New Age How Technology keeps this storage ahead of the race About the Realities of this Storage Why Tape? 10 good reasons

5 What has the world been doing? 35 ZB Zettabytes About 40% y/y CAGR 135 Million Petabytes Terabytes Gigabytes Source: IDC 2011

6 Protecting & Storing 35 Zettabytes of data (That s 35 Trillion Gigabytes) 35 ZB Zettabytes Storage requirements growing 20-40% per year Archive requirements growing 40-50% per year 135 Million Petabytes Storage budgets up 1%-5% Terabytes Gigabytes The information explosion meets budget reality Source: IDC 2011

7 The Dynamics of Computer Storage Today Data Enables your Business $$$$$ $$$$$ Primary storage Block based RAID, File based network disk Days Protective Storage Physical Tape, Disk, Dedupe Weeks Operating Storage Protection Protection of storage Active Data Repositories (more frequently accessed) Preservation Compliance Saleable assets Months Source: IBM Marketing & Development Custom Solutions Content collectors Data is your Business Passive Data Repositories (less frequently accessed) Vaults Federated Archives, Decades $

8 Storage Device Areal Density Landscape AREAL DENSITY (Gbit/in²) HDD Highlights density increased at 100% per year (GMR) w/ 20%-30% CAGR projected TAPE Highlights - Sustained 40% density increases with demos showing potential for greater increases HDD Products NAND Products TAPE Products TAPE Demos HDD 40%/yr NAND TAPE 40%/yr bit/cell Source: IBM research (Decad, Fontana,Hetzler) HDD 100%/yr HDD 20%/yr Optical 20%/yr HDD 40%/yr YEAR HDD 20%/yr?? Tape demo 75%/yr NAND 40%/yr 2 bit/cell technology enablers must scale What are the likely capacity points? What does this mean for your storage strategy?

9 Lithographic Scaling: Tape s Advantage Tape will maintain 40% CAGR Tape feature sizes and bit cell are much larger than HDD - Lithographic capabilities are not a limitation Media technologies required have scaled Areal Density demonstrations are exceeding 40% CAGR Source: IBM research (Decad, Fontana,Hetzler)

10 Fujifilm Tape Density Achievement 35TB Jan IBM Research, Zurich: recorded data onto an advanced prototype tape featuring the new Barium Ferrite magnetic particles developed by Fujifilm with improved performance and archival life compared to current metal particle technology. Density of 29.5 billion bits per square inch -- about 39 times the data density of tape in the 2010 market More than 25-fold increase in the number of tracks New critical IBM technologies were developed: Dramatically improved precision of controlling the position of the readwrite heads Improved detection methods to increase the accuracy of reading magnetic bits Low-friction read-write head 2012: demonstrated 100 billion bits per square inch The Next step in developing technologies to achieve tape areal recording densities of 100 billion bits per square inch and beyond Source: Fujifilm& IBM research

11 2011 INSIC TCO and Tape Media Conclusions Consortium of companies focused on the technical competitiveness of tape (IBM, Oracle, HP, Quantum, Spectra, Symantec, Imation, FujiFilm) 8.5x 10x -26% CAGR Energy used for tape: 96% less over 5yr projection

13 Is Tape still in use?

14 Which Best Describes Your Primary Backup Methodology? Backup to tape (D2T) 22% Backup to a VTL, then data moved to tape (D2D2T) 25% Backup to disk (not a VTL), then data moved to tape (D2D2T) 26% 73% Use Tape Backup to a VTL - all data stays on the VTL until purged (D2D) 11% Backup to disk (not a VTL) - all data stays on the disk until purged (D2D) 16% Only 1 in 4 use disk only Source: Gartner, 2011

15 The Linear Tape File System format LTFS creates access to data similar to a 2.5TB* memory stick! A File System for Tape! - Manage files easily with drag and drop directory tree access - Uses LTO-5 or LTO-6 dual partition capability to store the index and the content *LTO-6 uncompressed capacity Self Describing Tape - No application software dependencies - Ideal managing long term archives - Cross platform sharing of file-based as well as unstructured content Created by IBM Research, Commercialized in 210 (IBM Single Drive Edition) - LTFS Spec shared by IBM as open standard to LTO Technology Providers - Many Tape storage companies offer freeware versions for Windows, MAC OS, Linux and other operating systems

16 Making Tape more relevant to existing and new use-cases Existing use-cases Backup and Restore Disaster Recovery Archiving offline / Long-term Preservation Traditional Big data Storage - Scientific research / exploration Emerging use-cases driven by LTFS Active Archiving (online tape / disk blend) New Big Data - M&E, DVS, analytics Cloud storage All use-cases can benefit from Disk AND Tape
