Drivers of storage growth

1. New data from new applications (MASP, task manager, workflow, STIPAD, STIMER, STIRON, Internationale uitwisselingen, enz…)

2. Replication of data over 2 datacenters for disaster recovery (+/- 35%)

3. Snapshots and mirrors (+/- 10%)

4. Multiplication of environments (DEV, PRE-INT, INT, ACC, REF, FORM, PROD)

5. Multiplication of data for datawarehouse and BI

6. Multiplication of data for data-flow between projects/applications

7. Multiplication of servers by virtualisation (server sprawl)

8. Digitalization of paper files (aangiften, dossiers ) and archives of digitalized information

p. 9

8. Digitalization of paper files (aangiften, dossiers ) and archives of digitalized information

9. Centralisation of unstructured data (e.g. opslag van landmeterplannen, kadastrale gegevens, gegevens van de geografische informatiesystemen (CADGIS), audit van boekhoudingen)

10. Collaborative tools (email, voice over IP, Lotus Sametime chat, shared drives, Microsoft Sharepoint, Lotus Quickr, eXo-platform, …)

11. Storage of technical data (audit-logs, workflow, monitoring and logging,…)

12. Storage for new tools or new usage-policies (e.g. unlimited mailbox)

13. Capacity necessary for technical migration of servers and applications

14. Capacity necessary for backup of data on PC’s and laptops from the PFSFinance staff

15. Over-allocation of storage caused by wrong volume estimations of developpement teams

16. Lack of re-use of storage resources

Backup and off-line storage

�Backsoftware: � EMC Networker v7.5

• Backup-agent for each OS

• LAN-less backup by Networker Storage nodes (FC) for high-volume servers

• LAN backup for small-volume servers

• NMDA module for online backup of databases and mailsystems

• VMWare VCB used as storage node

p. 11

• NDMP voor NAS backup

� Mainframes: use their own backupsoftware

�Improvements� Backup policy standardization

� Reduced impact from mechanical devices (tape robots)

� Improved restore time

� Robust DB transaction log backups

Backup organization with Networker and DataDomain Oktober 2010

p. 12

DATADOMAIN observations

� Objectives:

� 1 month backup on disk

� Reorganization to tape for backups older than 1 month

� Backupwindows of 15 hours (no backups during

p. 13

hours (no backups during business hours)

� Throughput: 750 MB/s

� Deduplication ratio: 6,5 / 1 (+/- 85% volume savings)

� Backup window = OK

� Total volume DD880 needs to be increased

� Store less backup data

� Tape free backup becomes possible

� Reduce complexity of backup environment and increase robustness of backup solutions

� Move less backup data

� Replicate backup data without requiring huge bandwidth

Benefits of data deduplication

p. 14

� Replicate backup data without requiring huge bandwidth

� Backup of remote office

� Backup of VMware Servers

� Backup dense file servers

� Resolve LAN constraints, preserve firewall bandwidth, etc.

� Reduce backup Windows (VCB)

� Stop shipping FULL copies of data around when we know only a few % has changed since previous backup

Archiving

p. 15

� Archiving is an area in evolution

� Focus on legal archiving (archiving / deletion policies still under discussion)

� Use of filenet as central repository for metadata

Future evolutions

� Volumes will continue to grow (> 1PByte primary storage)

� Automatic tiering in arrays to optimize performance and disk usage

� Archiving as domain under developpementIncreased data move to Centera (to avoid backups and to optimize cost)

� Backup optimizations

Move file-systems to NAS

Oktober 2010

p. 17

� Move file-systems to NAS

� Increased use of VCB (and VADP in future Networker versions)

� Deduplication as core technology (attention for change mngmt)

� Storage for end-user computing

� Virtual desktops

� PC-backup and home drives

� Improved monitoring, Service management (capacity planning) and IT automation
