8 Why tape? $5000 Solid State Disk ($2000-$5000) SCSI, FC
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. $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 Value advantage of tape over disk expected to hold for next years Value of tape increases as carts/drive ratio increases Virtual tape will enable: Easy migration Reduce number of RTD and media Improved performance (random access and time to first byte)‏ Open systems virtual solutions in development Source: Horison Information Strategies

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

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

12 Disk to Disk to Tape Backup
Add disk to existing backup servers No additional hardware or software Backup servers Tape automation Application 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).

13 Disk to Disk with Virtual Tape
Add virtual tape services with a storage appliance Tape automation Backup servers Application servers VTL virtual tape library 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.

16 Data Access Requirements are Always Changing Inferred by business use
The reaility is the information lifecycle is dynamic. Data may need to be recalled at various times in its lifecycle, in a very unpredictable manner. Examples are when a mortgage is refiananced or when a patient gets sick, records would need to be recalled, and would need to be accessed quite often for a period of time. It may not be effective to have this data stored on secondary or archived storage solutions. .The problem is that most ILM strategies move data in one direction only, from primary to secondary or tertiary storage. In a traditional ILM strategy, when data moves to tape, it stays on tape, even if the data goes active again. When users recall a file, they are either accessing it on tape and getting less-than-optimal performance, or they make a new “active” copy of the file, contributing to data sprawl.

New Data “Lifecycle” Journey Challenge is Inclusive Mgt., Access & Cost of 'new' Archive Data Data Consumers NEW ACCESS Security & ID Mgt. Envelope Eternal Data Creation Offsite Tape Vault Data Archive Ephemeral Data Disposal Data In Use Backup Retention @Date Data Management

18 Archive Requirements Are Changing
The dynamic nature of data is also changing the nature of archive...in the past archive meant data was protected for the purpose of recovery- data was saved to tape, which was later moved to an offsite location- and only recalled when there was some type of failure. Because of the high costs of storing data- more and more organizations are utilizing archive solutions- disk or tape for storing “persistent” data- that which is not accessed often but cannot be moved offsite for long term archive. Compliance regulations which require that particular data be accessed ithin a set period of time also drive the need for intelligent” archive devices that can quickly search for and retrieve specific data sets.

43 Archive Software

44 ‘Infinite Disk’ Technology
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. Free Space Active Data (Frequently-Used Files) Pointers to Inactive Data on Secondary Media

45 SAM-FS Function: Archive
Populate all tiers of storage based on data policy File Servers Users On-line Secondary Storage Documents Data copied to media by policy Automatically populate all desired tiers of storage Documents Spreadsheets Presentations Images Printstreams Databases Video/Audio Messaging Spreadsheets Presentations Images Printstreams Databases Video/Audio Messaging LAN/SAN Clients Generate up to 4 copies concurrently Data written in TAR format Optimized writes based on file size Shell command for immediate response The ARCHIVE function interrogates the file system for new data or for data that has been updated. There is a data policy that is defined during setup that governs how often this function runs, what tiers of storage it is to use, and how much storage resource is available for the archive function (ie 2 tape drives, 3 tape drives, etc.). Data policies governing the behavior of the ARCHIVE function can be established by application, by file system, by directory, even by file size and file type. The ARCHIVE function is transparent to the application being managed. Up to 4 tiers of storage can be populated with newly created or updated data. The data is written in TAR format which is important for worse-case scenarios where the application environment has to be rebuilt with nothing more than the data itself being available. This approach to data management enables users of ASM to automate the data protection and business continuance function. The ARCHIVE function can be set up to run on a specific time interval (ie once an hour), or at a specific time (ie 6pm each evening), or based on a specific application event (ie end-of-day process). There is a shell command for manual execution as well. Off-Site Storage

46 SAM-FS Function: RELEASE Automate primary disk space management
File Servers Users On-line Secondary Storage Documents Data copied to media by policy Documents Spreadsheets Spreadsheets Presentations Presentations Images Images Printstreams Printstreams Databases Automatically populate all desired tiers of storage Databases Video/Audio Video/Audio Messaging Messaging LAN/SAN Clients Release only after valid copy exists Release directly after archiving Release at Watermarks Never Release – data stays on disk Shell command for immediate response The RELEASE function like the ARCHIVE function, has a data policy that is established during product set up. It’s function is to automate the space management function for primary disk. These data policies can be changed on the fly. The customer can even have one set of data policies set to run during normal business hours and have a completely different set of policies, usually to reallocate shared resources, for off-hour operations. Freeing up primary disk space can be accomplished as copies of the primary data are created, or at specific watermarks. The policies for the RELEASE function can even be set up to “Never Release” certain critical data that is under ASM’s control, populated to secondary storage, but must remain on disk at all times. As mentioned for the ACHIVE function, the ASM administrator can manually run the RELEASE function from any ASM master console. Off-Site Storage

47 SAM-FS Functions: STAGE Managing retrievals from secondary storage
File Servers Users On-line Secondary Storage Documents Spreadsheets Presentations Images Printstreams Databases Video/Audio Messaging Data copied to media by policy Documents Spreadsheets Presentations Images Printstreams Databases Video/Audio Messaging Automatically populate all desired tiers of storage LAN/SAN Clients Associative Staging Files can be staged in groups Read-behind Stage - Data immediately available while file is being retrieved Never Stage - Direct read on retrieval request from secondary storage Policies for the STAGE function control how data is to be managed when being retrieved from secondary storage. I can have a data policy set for seldom retrieved data, to mount a tape for example, read the requested file, present it directly back to the requestor without that data ever being staged back to primary disk. At the same time, I can have a completely different application that may requests data that has been archived to secondary storage and released from primary disk, that once requested, may have many requests for that same data for a short period of time, to be staged back to primary disk and retained there for the time frame of usage (ie a few days, a week, a month, etc.) During the STAGE function, there is a feature called Read-Behind-Stage, that allows for portions of a large file to be immediately available as each logical container is written back to disk. This enables much improved response time from an end-user perspective. Without this ASM feature, the user would have to wait for the entire file to be restored to disk before any part of it could be accessible. Off-Site Storage
