© 2010 IBM Corporation3 What It Takes For Good Deduplication Results What is required for good deduplication: –Retaining multiple generations of same files –Files whose content does not change significantly from one generation to the next –Applications that do not embed changing metadata from one generation to the next Exception – TS7680G has parsers for HSM, FDR, and DFDSS –Files whose content is not significantly rearranged between backup iterations What types of files should deduplicate at acceptable levels? –Any that meet the above criteria –Backups –Archives – history files recreated periodically adding/dropping records –z/OS system volumes –Libraries –Databases
© 2010 IBM Corporation4 TS7680G ProtecTIER Gateway for System z A complete System z data deduplication and remote data protection system for z/OS, z/VM, and z/VSE Features inline data deduplication capacity and performance options Architected to meet enterprise level availability demands –Integrated package features enterprise rugged components –Redundancy throughout provides failure protection –Field proven ProtecTIER software in a cluster configuration Simple implementation on System z as an automate tape library Gateway architecture preserves customer choice for disk storage –May be DS5000, DS8000, Storwize V7000, XIV Enterprise disk and other certified arrays from EMC, HDS, etc. Backed by IBM’s global service and support - 1PB of physical storage- Two to eight FICON channels virtual tape drives- 1M tape VOLSERs - 800MB/Sec- Replication

TS7680G FICONFC HyperFactor Key Differentiation: No HASH Tables – Eliminate False Positives Binary Diff Compare of Similar Data Repository: Index Ratio 250,000:1 - Index fits in RAM for repository up to 1PB Yields Scalable, Predictable, Performance
© 2010 IBM Corporation8 Replication Overview TS7680G replication is different from and not a part of TS77xx Grid TS7680G replication is done using native ProtecTIER replication TS7680G replicates all virtual tapes that have active data z/OS systems typically use one common scratch pool for all applications so use of the VOLSER which ProtecTIER uses for creating replication policies is not practical – DFSMS Advanced Policy Management support is planned ProtecTIER replication policy controls when replication is done: Replication may begin as the tape is written, when the tape closes, or may be scheduled to begin later Replication is unidirectional from the spoke/production site, to the hub/disaster recovery site Replication is done at the tape volume (VOLSER) level transferring: Metadata Deduplicated user data EXVA (Extended Volume Attributes) Category and scratch information as necessary All metadata is transferred but only the user data that has changed is transferred ProtecTIER may be queried for list of fully replicated volumes

Their tape data was growing rapidly for their existing environment. Batch windows were increasing while space available on their tape library was shrinking. After evaluating EMC’s offering with Data Domain and Luminex, they quickly turned to IBM’s integrated TS7680G ProtecTIER for z/OS as their enterprise level solution. Solution TS7680G Deduplication for System z XIV Disk IP-based replication Application Tape Replacement - Eliminate existing tape systems Benefits Provides customer with scalability and performance in all their tape processing and backup/recovery operations Provides cost-effective replication for improved DR requirements Reduces footprint and offers more efficient management of environment Reduces bandwidth costs with deduplication averaging 6:1 for all data Protect More. Store Less.™. IBM’s TS7680G ProtecTIER for z/OS provides customers with a unified approach to backup and recovery with better performance and reduced footprint over their existing tape only solution
© 2010 IBM Corporation17 Baldor Electric Company Saving more while storing less with IBM ProtecTIER The need: Baldor Electric Company is a global leader in the design, manufacture and marketing of industrial electric motors, mechanical power transmission products, drives and generators. Faced with an aging physical tape backup system, the company needed a scalable virtual tape solution that could seamlessly integrate into its existing storage infrastructure. The solution: Working with IBM business partner Sirius and IBM, Baldor deployed an IBM ® System Storage ® TS7680G ProtecTIER ® Deduplication Gateway for System z ® and an IBM XIV ® Storage System into the company’s existing storage infrastructure, enabling faster and more frequent backups, faster data restores, and seamless data replication to a remote site for disaster recovery. The application: Distributed systems backups written to System z tape using FDR/Upstream z/OS SAP DB2 databases backed up using DFDSS Replication between Arkansas production site and Colorado D/R site The benefit: Enables a 14:1 database deduplication ratio Reduces backup times by 40 percent and restore times by 50 percent Quadruples the number of backup copies stored, from 7 to 28 Backup tapes fully replicated less than one hour after backups finish “We were sold on ProtecTIER the first time we looked at it. We read the tech specs and we thought that this is a perfect fit for what we’re doing.” — Eric Breuer, systems manager, Baldor Electric Company Solution components: IBM ® System Storage ® TS7680G ProtecTIER ® Deduplication Gateway for System z ® IBM XIV ® IBM System z10 ® Protect More. Store Less.™
