TS7680G Customer Experiences


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


TS7680G ProtecTIER Gateway for System z

TS7680G System Redundancy

ProtecTIER deduplication for the mainframe– Places two modified C06 control units in front of the two TS7680G ProtecTIER

servers to provide a FICON tape device interface and integrate with DFSMS – The TS7680G PT servers are in a clustered configuration for high availability

and performance

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

Baldor Electric CompanySaving 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/Upstreamz/OS SAP DB2 databases backed up using DFDSSReplication between Arkansas production site and Colorado D/R site

The benefit:

Enables a 14:1 database deduplication ratioReduces backup times by 40 percent and restore times by 50 percentQuadruples the number of backup copies stored, from 7 to 28Backup 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
