The Copy Overkill - Regaining Control

603 Aufrufe

Veröffentlicht am

Data floods streaming into data centers are further exacerbated by multiple copies of the same data. Multiple backups, archives, snapshots, data clones for development and business analytics are multiplexing data volumes and drive relentlessly the need for additional storage capacities and budget. Data copy management and storage innovations should be the next key IT initiatives to get data copies and storage cost back under control.

The Copy Overkill - Regaining Control

  1. 1. 0 Copyright 2015 FUJITSU Human Centric Innovation in Action Fujitsu Forum 2015 18th – 19th November
  2. 2. 1 Copyright 2015 FUJITSU The Copy Overkill – regaining control Marcus Schneider Head of Product Management and Development Storage
  3. 3. 2 Copyright 2015 FUJITSU Large Bank: >12 copies of data Local DC 1 Local DC 2 Remote DC Amount of data in storage Tier 1 Tier 2 Tier 3
  4. 4. 3 Copyright 2015 FUJITSU But it’s not just data protection Application Testing and Development 1 Application Retirement/ Migration 2 Active Archiving 3 Business Analytics 4
  5. 5. 4 Copyright 2015 FUJITSU The Copy overkill Capacity Time Primary Data Copy Data Chart shows a growth rate of 30% Each byte of primary data easily causes 25 bytes of copies Copies trigger 85% of HW spending Almost all copies sit idle
  6. 6. 5 Copyright 2015 FUJITSU Do I need backup? I have storage cluster  Virus  Wrong patch  Admin or user error  Software error 80% of Unplanned downtime goes along with data corruption High Availability protects you against hardware failure, but not against data corruption. Server Primary Secondary Switch Non-stop operation Storage Access
  7. 7. 6 Copyright 2015 FUJITSU The Backup Reality What will you do in case you need a backup? Only 50% of SMBs make daily backups Only 30% make VM backups Death after a disaster: 25 – 45% 50% No backup strategy
  8. 8. 7 Copyright 2015 FUJITSU Backup Considerations A backup is a copy with a time stamp  How many recover points do I need? How much data loss am I willing to accept? What is my Recovery Point Objective (RPO)?  How fast do I need my services to be available again? What is my Recovery Time Objective (RTO)?  How disaster resilient do I need to be? (how many remote copies do I need and how far away should they be?)  How much am I ready to pay for my insurance?  How many copies? At what location? On what media?
  9. 9. 8 Copyright 2015 FUJITSU Are all those copies really copies? Test/Dev: Copies for temporary use 1 Applications are primary data and need protection 2 Archives are primary data and need protection 3 Content Depots for analytics are copies for temporary use 4 COPY?
  10. 10. 9 Copyright 2015 FUJITSU Wouldn’t it be nice, if … You would have exactly the number of copies you really need, and only as long as you need them? Provisioning a copy would be self service, fast and easy? All copies could be managed centrally, with one easy to use GUI?
  11. 11. 10 Copyright 2015 FUJITSU The answer Data De-Duplication and Data Protection Infrastructure They are not all the same Smart use of Snapshots and Replication Concept wins over tools If you don’t know your Target, there is no shortest way to get there
  12. 12. 11 Copyright 2015 FUJITSU Concept: The Copy Balance High Value of copies Low value of copies Notenoughcopies Toomanycopies Add use cases Backup is important Increase efficiency Paranoia
  13. 13. 12 Copyright 2015 FUJITSU You need Data Protection Infrastructure – but Increase the ROI of your Data Protection Infrastructure by increasing the value of your copies Reduce your Data Protection Infrastructure by creating just the number of copies you need Do you really need every copy you generate today? How much primary storage are you using for snapshots? Any Flash? How many copies do you need off-site? What else can you do with those secondary copies of data? Analytics? Enable test/development without affecting production? Could anybody else benefit from read-only access to a copy of the data?
  14. 14. 13 Copyright 2015 FUJITSU ETERNUS CS Backup Appliances Integrated appliance incl. backup SW ETERNUS CS200c S2  Includes Commvault software and licenses  For disk backup and file archiving  Deduplication, replication functionality ETERNUS CS8000  Unified data protection platform for disk, tape and cloud  Complete consolidation and virtualization of backup IT  Unmatched scale-out scalability up to 22 PB  Leading DR and HA technology ETERNUS CS800 S6  Easy to use backup to disk appliances  Deduplication, replication functionality  Modular scalability Target appliance SW independent
  15. 15. 14 Copyright 2015 FUJITSU Checkmarks for Data Deduplication Perfect HW configuration for highest performance at lowest cost – Benefits of the Appliance form factor Variable Bit Length – The most efficient way with superior Dedup factor High Availability for Dedup – only with more than one node Inline – immediate start of replication, use the full capacity Is my data suitable for Dedup? (e.g. encrypted data is not) Dedup as part of backup software (one vendor strategy) or backup software independent?
  16. 16. 15 Copyright 2015 FUJITSU The perfect Data Protection Infrastructure Capability Backup Software ETERNUS CS200 ETERNUS CS800 ETERNUS CS8000 Inline Dedup Typically yes Yes Yes Yes Variable Bit Length Typically no No Yes Yes Availability Medium Medium Medium High HW balance Medium High High High BU SW Dependent Dependent Independent Independent Capacity Medium Medium Large Largest Speed Low High High Highest
  17. 17. 16 Copyright 2015 FUJITSU But they typically lack It all starts with a snapshot  Immediately available “version” of productive data, very space efficient Disk arrays are capable of producing snapshots  A catalog – you soon lose control  Deep application integration – without that, it is not usable for restore  Process automation – leads to OPEX issues  Independence of a single product  Write access – that is good enough for back up, but not usable for test/dev You get all that by adding ETERNUS Snapshot Manager (ESM)
  18. 18. 17 Copyright 2015 FUJITSU Adding all that to array based snapshots: ESM ESM Create application consistent virtual copies of data Mount them from any server for any purpose Production volume Snapshot 1 Snapshot 2 Snapshot 3 Snapshot 1 Snapshot 2 Snapshot 3 Snapshot 1 Snapshot 2 Snapshot 3 Production volume Production volume
  19. 19. 18 Copyright 2015 FUJITSU Create a snapshot using ESM These snapshots can be mounted from any server, to be used for test/dev, analytics, etc.  DX supports read AND write on snapshots. E.g. You could test an Oracle update before you go live If you want to free the source DX, you can create a clone. That provides highest performance The snapshot can be accessed by any Backup Application and can be written to any target (CS, cloud, S3, CD) Near CDP: One snapshot every 15 minutes Live test of retired applications possible
  20. 20. 19 Copyright 2015 FUJITSU Two flavors of end-to-end copy management  Snapshot on DX, triggered by ESM  Any Backup Software reads the snapshot and writes a backup  ESM + Backup SW on server  To a target, e.g. CS800, CS8000 ESM + Backup SW ESM + CS200  Snapshot on DX, triggered by ESM  CS200 contains ESM and Simpana, reads the snapshot, writes it to local disk and/or replication target, cloud  Or a large target like CS8000
  21. 21. 20 Copyright 2015 FUJITSU ESM/CS200 and ETERNUS CS8000 Commvault … Why do I need a CS8000? … uses a single index engine, single pass data movement and a single storage repository for backup and archiving consoli- dation  singe pane of glass copy management.
  22. 22. 21 Copyright 2015 FUJITSU Purpose-Built Backup Appliance (PBBA) Monolythic targets are single points of failure. If one fails you can’t restore its data. And they are performance bottlenecks Using a large file pool at the backend. CS8000 ViNS provides such a dramatically scalable and fast pool. Single Media Agent failures are no issue any more. Solution ETERNUS CS8000 Disk/Dedup (VTL/NAS) (Cloud)Tape ETERNUS CS200c ETERNUS CS200c ETERNUS CS200c Media Agent Media Agent Media Agent Primary storage (e.g. ETERNUS DX) Servers (e.g. PRIMERGY)
  23. 23. 22 Copyright 2015 FUJITSU Consolidating Copy management to a combination of Commvault and ETERNUS CS Increase the efficiency of your Data Protection Infrastructure. BUSINESS BENEFITS Better RPO, RTO, adding remote copies for disaster recovery easily One integrated environment for managing all copies, including backup and archiving, replication and DR Increase level of automation significantly, increase productivity of highly skilled IT staff
  24. 24. 23 Copyright 2015 FUJITSU More Benefits of Commvault + ETERNUS CS Add value to your Data Protection Infrastructure. BUSINESS BENEFITS Application retirement: free VMs from rarely used apps Active Archiving: Free primary resources from rarely used data  Less DB licenses, reduced backup times, making archiving cheap and easy Developers have fast and easy access to real, up to date data: better apps, faster available It is fast and easy to test changes, e.g. patches and updates: reduce risk of failure Easy access to live data for analytics
  25. 25. 24 Copyright 2015 FUJITSU Stechert Stahlrohrmöbel GmbH „Fujitsu’s customer service is simply better than the other providers.“ Maintain a permanent backup of the SAP database Cope with future expansion (acquisitions) DX + ESM + SEP + CS800 A consistent snapshot every 30 min. “The main reason behind our decision to invest in the Fujitsu ETERNUS technology was that it enables us to quickly resume productivity after an IT failure”, says Zimmermann, Head of IT, Stechert Stahlrohrmöbel GmbH. “Before, we would lose whole days’ worth of data, or really struggle to find it. Now it is max 30 min.” Head of IT Harald Zimmermann, adding:
  26. 26. 25 Copyright 2015 FUJITSU Efficient Copy management? Yes, we can!
