1 Data Protection in 2006 A look into strategy, technology and design Rothery Harris Storage Technical Advocate Hewlett-Packard Network Storage Solutions 2004 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice

2 Agenda Introduction Backup philosophy & ILM Enabling technologies Disk, tape, optical Tape library technology Storage Networking Legal compliance Putting it all together in an Enterprise Solution 2

3 Backup Philosophy zero downtime multi-level backup restore life cycle data management snapshots, clones & mirrors security 3

4 Backup in 2006 Enabling Technologies 4

5 Disk drive technology in the future magnetic disk recording densities have been growing at 60% per annum densities will approach the Superparamagnetic limit where magnetic signals on the media become unstable (this is currently estimated at 40G bits per in2) Using perpendicular recording techniques and advanced media 3.5 disks of around 1000GB will be available in 2006 Advanced technologies such as near field and crescent recording will take disk storage beyong these limits by an order of magnitude 5

6 Disk interfaces - Serial ATA Serial Attach ATA uses 4-wire low voltage differential connection to acieve data transfer rates of 150MB/s (gen. 1) Ideally suited for low cost disk arrays (parallel ATA was not!) - point-to-point connection 3 generation roadmap (gen1-150mb/s, gen2 300MB/s, gen 3 600MB/s connectors available for hot-plug environment can be used with Serial Attach SCSI 6

7 Disk interfaces - Serial Attach SCSI (SAS) Parallel SCSI is limited to Ultra 320 speed due to signal jitter (max. 160MB/s) developed as a logical extension of the existing SCSI standards serial full duplex 4 wire connection roadmap of 1.5Gbps, 3Gbps,6Gbps (3Gbps available by 2006) enables dual port 3.5 inch form factor disk drives software compatible with Parallel SCSI point to point connection but with port expanders available to increase the number of connections allows 6m compact cable length at 3GBps 7

8 Magnetic Tape Is there a future for tape?

9 Ultrium vs SDLT Tape Roadmaps--Native Capacity Native Capacity (GB) Year of Introduction LTO-A SDLT 9

10 Ultrium vs. SDLT Tape Roadmaps--Native Transfer Rate Transfer Rate (Native MB/s) Year of Introduction LTO-A&B SDLT 10

11 Tape and Optical technology in 2006 Generation 3 Ultrium tape (with WORM capability) Generation 6 DDS Generation 3 SDLT tape T-series STK Super AIT 11

12 Linear Tape Open - the way ahead! 4 Generation Roadmap - 2 generations in service defined - 2 more generations in planning WORM generation 5, 6 LTO Ultrium generation 1 200GB LTO Ultrium generation 2 400GB LTO Ultrium generation 3 800GB LTO Ultrium generation 4 1.6TB compressed capacity 20-40MB/s 40-80MB/s MB/s MB/s compressed transfer rate 12

13 DDS Roadmap Enabling Technologies Native Capacity Native Transfer Rate DDS-1 (1991) 90m Tape DCLZ DDS-2 (1993) 120m Tape MP+ media Thinner Tracks DDS-3 (1995) MP++ media Increased bpi Format efficiency DDS-4 (1999) 150m Tape MP+++ media Thinner Tracks 5 th Gen DDS (DAT 72) (2003) 170m Tape MP++++ media Thinner Tracks 6 th Gen DDS (2005) Format TBD - Media enhancements and or Increased bit density 2GB 4GB 12GB 20GB 36GB 70-80GB 183kB/s 720kB/s 1.5MB/s 1-3MB/s 3MB/s 5MB/s 7 th Gen DDS (2007) Format TBD - Media enhancements and or Increased bit density GB 8MB/s 13

14 Tape Media Terabyte per tape is a reality - developments in Nanoparticle technology remove the traditional barriers of coercivity/magnetization. Enable thinner magnetic coatings and therefore thinner longer tapes. 14

15 Optical Storage 15

16 Optical Storage Technology Evolution CD λ = 780 nm NA = mm substrate DVD λ = 650 nm NA = mm substrate UDO λ = 405 nm NA = 0.7/ mm cover layer 16

17 UDO Optical roadmap 17

18 Tape Library technology for 2006

19 Tape Library technology towards 2006 SAS & 4Gbps Fibre Channel Intelligent controllers Advanced management Disk to disk to tape SATA low cost disk array built in SMI-S standard implemented Modular and scaleable hardware 19

20 Future Library Architecture concepts SMI-S Storage Storage Area Area network network 4Gb fibre channel iscsi option management software network interface management SATA 100baseT FC or Serial Attach SCSI - dual port controller tape drive(s) controller controller card cage tape tape drive(s) drive(s) picker management controller library controller ACI Enterprise Systems Tape Library 20

21 Storage Networking technology to 2006 and beyond 21

22 Fibre channel future directions 10 Giga bit 4 Giga bit DWDM (now) CWDM (now - lower cost) Metro - area fibre (more cities) 22

23 Gigabit Ethernet & beyond IEEE 802.3ae defines 10Gbps ethernet less expensive technology than SONET for metropolitan area networks and wide are networks 10Gbps ethernet is a fat enough data pipe for Enterprise storage products competes with ATM for WAN TCP/IP offload essential for good performance 23

24 TCP/IP offload engine [TOE] out of order processing in order delivery slow start sliding windows ECN HOST CPU fast retransmissions congestion control window probe timers Network Card TCP checksum TCP re-assembly Host CPU Network Card out of order processing in order delivery slow start sliding windows ECN fast retransmissions congestion control window probe timers TCP re-assembly TCP checksum 24

25 iscsi vs Fibre Channel iscsi price performance common network components lower cost Metro-area connections (gigabit-e infrastructure) Fibre Channel mature technology 4 and 10Gbps soon complete solution greater data security 25

26 Legal compliance 26

27 Legal requirements now & future USA mandatory SEC17a NASD 3010 US Food & Drug CFR part 11 European Union EU regulations still under development but companies and organisations are still liable to individual country legal requirements (eg United Kingdom - Data protection Act) 27
