Why Network Appliance Solutions are GREAT for Database Environments
Net. App’s Database Customer base · Currently over 1300 Database customers. . . · Market presence runs deep as well; Net. App powers… · 9 out of top 10 ISPs · 13 out of top 15 web sites · 41 of Fortune e-50 Index companies • • • Banks Airlines Automotive Government Oil & Gas 16
The Net. App Advantage · Dramatic improvement in solution availability · Reduction in operational cost, complexity, and deployment processes · Typical customer experience is a faster database environment · Scale seamlessly while experiencing rapid growth 17
Causes of Downtime Source: Windows 2000 Magazine 6/2001 18
Snapshot, Snap. Restore and Snap. Mirror Provide Immediate Relief • Use Snapshot/Snap. Restore for full scale tests on production environment • Take a Snapshot, run the test, then use Snap. Restore • Reduces recovery time risks • Use Snap. Restore as security for maintenance like planned SWUpgrades, Data Uploads, etc • Use Snapshot for Offline Backup • Reduce downtime to a few minutes (cold backup) • Use Snapshot for Online Backup • Reduce the time you’re in degraded/vulnerable mode to a few minutes (hot backup) • Use Snap. Mirror for Disaster Recovery • Snap. Mirror provides efficient replication of database files to a remote location or DR-site 19
Constantly Challenged with Planned Downtime Scenarios Key Reasons for Planned Downtimes… Software Upgrades 27% 25% Server Upgrades DB Maintenance 14% 8% Y 2 K Testing Backups 6% DW Loading 3% Hardware Upgrade 1% Storage Upgrade 1% Others 26% 0% 5% 10% 15% 20% 25% 30% Source: Strategic Research Corporation, 2000 20
Fast Recovery from Unplanned Downtimes Database Recovery Scenario - An Example l l l 300 GB database and the entire database requires recovery Tape recovery time is 60 GB/hour Normal recovery time is 5 hours + log replay time Snap. Restore reverts volume to same state as when backup was taken. Duration - 3 minutes Total recovery time: 3 minutes + log replay time Database Gigabit Database Instance F 760 Logs 21

DB 2 ‘Write Suspend’ functionality • DB 2 has delivered two new features in Version 7. 2: • Suspended I/O • db 2 inidb utility 47
DB 2 ‘Write Suspend’ - db 2 inidb utility • The db 2 inidb utility operates on the mirrored copy -Perform crash recovery -provide a duplicate copy of the database for reporting purposes -Put the copied database in a roll-forward pending state and roll forward the database -keeps the mirrored copy synchronized with the primary database -Allow the mirrored copy of the database to be backed up -backup that does not impact the performance of the primary database server. 48
