3 3 Introduction Data Protection Techniques Data Archiving Techniques Tools

4 4 Difference between Backup & Archive Backups are created to recover from errors > Cost effective data protection > Off-site storage > Backup is important – Restore is Critical Archiving for Information Lifecycle Management > Storing data on different media based on policy > Right Data, Right Place, Right Price

5 5 Data Protection Techniques Disk Mirroring / Replication Disk to Disk Backup Disk to Disk to Tape Backup Virtual Tape Libraries Continuous Data Protection Disk to Tape

6 6 R&D Marketing Financial Data Criticality Time Optimizing The Life Cycle of Data

7 7 89% of all digital stored data is on tape and …

8 8 Why tape? $0 $15 $30 $45 $60 $5000 Average price per GB Automated Tape ($.50-$3.00) Economy Disk ($3-$15) JBOD, MAID, SATA Optical Disk Blue Laser ($15-$35) SCSI Enterprise Disk ($40-$70) FICON, ESCON, SCSI, FC Midrange Disk ($15-$35) SCSI, FC Solid State Disk ($2000-$5000) SCSI, FC Storage Device Category Source : Horison Information Strategies All prices are ASP per gigabyte for working subsystems. The price per gigabyte decreases as the ratio of cartridges to drives increases, diverging from disk costs. Automated tape prices include drives, media and library and use a 2-to-1 compression factor. Tape cartridge capacity growing faster than disk drive capacity. Tape pricing per gigabyte now diverging from disk pricing.

10 10 Traditional Tape Based Backup Primary storage to archival storage Direct relationship with tape devices Additional device sharing software Application servers Tape automation Backup servers Data moves directly from primary storage to tape and is managed by the backup application

11 11 Disk to Disk Backup Add secondary disk storage > Part of existing disk subsystem or as an external appliance Application servers Tape automation Backup servers Data moves from primary storage to temporary disk buffer. Backups usually take place from the temporary location to tape. Data protection appliance - Snapshot/mirrors - Continuous data protection (CDP) Disk based snapshot/mirroring

12 12 Disk to Disk to Tape Backup Application servers Tape automation Backup servers Data moves from primary storage to the temporary disk buffer and then on to tape. Data movement is managed by the backup application. Recoveries will normally come from the disk buffer(s). Add disk to existing backup servers No additional hardware or software

13 13 Disk to Disk with Virtual Tape Application servers Tape automation Backup servers Data moves from primary storage to the VTL disk buffer under control of the backup application. Recoveries normally take place from the VTL buffer. If a real tape cartridge is required then the backup application is responsible for creating it. VTL virtual tape library Add virtual tape services with a storage appliance

24 24 Tape Drive Characteristics All figures are native Average access time includes 4 seconds robotic time, load and average search Enterprise class

25 25 Lets see the difference for archive! Components of recall time > Mount tape (by robot) > Load tape > Find block > Transfer data > Rewind > Unload > Dismount tape (by robot) It doesnt help if this component is fast when the rest are slow.

26 26 Choose the Right Tape Technology Capacity > Important for backup > Very important for most archive requirements > Not so important for HSM functionality Throughput > Important for backup and archive > Backup must write several stripes because of the speed Loadtime > Important for HSM functionality Reliabilty

27 27 Nearline Technologies

28 28 SL8500 SL8500 has been adopted at more than twice the rate of other new StorageTek large libraries Broad acceptance in financial, government and broadcasting segments 39% shipped are to customers who have never purchased Sun/StorageTek enterprise libraries before

29 29 StreamLine SL8500 architecture SL8500 can be share across heterogeneous applications and servers > ACSLS software support > Allow multiple tape drives and media types SL8500 designed for consolidation > 24x7 design > Multiple and simultaneous mounts/dismounts > Scalability in capacity and tape drives: from 1448 to slots cartridges, from 1 to 448 tape drives > Multiple media types > High density > High performance

31 31 ~1,500 cartridges ~3,000/5,000 cartridges ~10,000 cartridges Library base size and expansion frames Customer Requirement: Flexibility and Scalability

32 32 24x7 availability Redundant powers All critical internal components are redundant Redundant robots Live library upgrades > microcode > Add and replacement of tape drives > Add and replacement of robots > Add and replacement of power and electronics > Add new library > Add cartridges slots

33 33 THE L1400 TAPE LIBRARY EMPOWERS CONSOLIDATION Share library resources Grow with ease Customize your configurations Use multiple technologies Increase availability Work within flat or shrinking budgets

34 34 KEY L1400 LIBRARY FEATURES Continuous Capacity TM technology > Superior scalability - grow easily when you need to Partitioning > Share the L1400 tape libraries without additional components High Performance > Reduce backup times with high robotic and throughput performance Any Cartridge Any Slot TM technology > Configuration flexibility and investment protection Sun Services > Experience and coverage to support your consolidated data

35 35 The Judges Reach Their Decision - Sun StorageTek L1400M Product of the Year As one of our judges put it, it may be "somewhat contrarian" to give the gold to a tape library in 2006, but Sun Microsystems Inc.'s L1400M solves a top problem in tape : > The ability to use four different tape formats within a single library It's a solution that's been a long time coming.

44 44 SAM-FS creates a virtualized or infinite disk that extends primary or secondary storage onto any number of additional media and devices. Virtualization optimizes storage capacity – automatically migrating inactive data to near-line secondary media – while also giving users immediate access to ALL of their data, regardless of where it is stored.
