Dynamic InfrastructureVirtualization


Tivoli software

Separation between production and backup processing non-production processing relocated to an auxiliary server data copy contained within storage subsystem

- fast ‘pointer copy‘- background data movement

FlashCopy Solutions - ‘virtualized‘ Backup

AuxiliaryServer

mySAPDBServer

Disk Subsyst

FlashCopy Solutions separate backup from production processing. Backup jobs and windows no longer affect

- application availability- pace of system administration/management tasks,

e.g. space extension, patch application, migration Added-value processing enabled, e.g. DB verify, cloning


Tivoli software

FlashCopy Solutions provide a complete workflow to control allprocess steps, synchronize execution between the different systems deploy FlashCopy technology for near-instant copy processs eliminate scripting by a product-based offering, e.g

24x7 worldwide support, continuous maintenance, joint verification with SAP

FlashCopy Solutions – production-ready process

AuxiliaryServer

mySAPDBServer

Highly automated, production-oriented data protection functionality- robust, e.g. dynamic resource enumeration, extensive checking/retries, error detection/messages- tailorable via configuraiton parametersin a ready-to-run package (no scripting)

FlashCopy is a hardware technology command issued when copy is needed no presync necessary

source and target volumes immediately available, each with r/w access

copy options (background within subsystem)nocopy (copy on change only) copy option (full background copy)incremental (changed blocks only)

multiple source-target relations

'zero impact' Backup

- no load on production server

no prescheduling- short DB backup window

perform backup anytime- disk and/or tape media - balancing of tape workload

'Flashback' Restore

- restore from FlashCopy on disk - recovery starts immediately after

Flashback Restore- consistent process and user

interface for tape/disk restore

on demand Cloning (Service Offering)

- no intermediate backup- short time to activate clone - automated, customizable

built on a common base product

Quotes on FlashCopy Solutions

Quote from Dutch Business Partner BP Solutions on their customer E., NL:My customer E is a current user of IBM pSeries and IBM Sharks. One of the nice features they like very much is TSM for Hardware which makes it possible to create online SAP backups with minimal disturbance of the production environment.

Quote from customer Hugo Boss, Germany:FC Cloning works fabulous! Runtime approx. 11 minutes. Adding some remaining manual prostprocessing we can clone our production system in 30 minutes. Many thanks for the competent support during implementation.FC Clone copies are placed on order.

Quote from a member of the team at customer U, UK, on TSM for Advanced Copy Services (aka TSM for Hardware) and FC Clone:For the record, I am well impressed by what this product does especially with the speed of the recovery process.I am sure when we come to demo this to U they will be suitably impressed as well especially considering the complexity of what it is dealing with. Legato are long way behind providing this capability with their product and they are currently looking to scope and price an interim scripted solution for U.
