  3. Session Pace • We have a long way to go and a short time to get there…. • Answers on my blog….. • If you want to talk more about something STOP me. • I may ask to take something offline. Find me after the session or at lunch

  4. Agenda • Challenges • What is really the most important? • Recoverability • Stability • Performance

  5. What are the Challenges are you seeing? • Bigger databases take longer to maintain. (Backups, Re-indexing, upgrades,… ) • Higher the availability the higher the price tag. (Disk space technology for a cluster is not going to be cheap) • Global Economy  Global Business/Customers  around the clock availability • Resources become harder to manage • SQL Server standard will become more challenging (table partitioning, database mirroring, backup compression, TDE) • Insufficient test environments (buy really cool hardware now do it twice) • Lack of head count • Growth Pains (fighting policies, technology debt) • Example…

  6. Now What? • Define what is really important and prioritize it. Here is my list. (This could be different for each of us) • Recoverability • Stability • Performance • What have I done now and in the past to make sure that the priority list is actually being addressed.

  7. Step One • Management database • Determine coverage times, how do you accommodate for odd hours • Third Party tools • Management companies • Hosting companies • What are the sore spots?

  8. Recoverability • Backups • Full Diff  T-Log • Compression • Third Party Products • File Groups • Retention Policies • Practice Restores • Plan your tests, and test your plans • Backup your staff

  9. Stability • Redundancy • High Availability • Role Segregation • Maintenance • Why DBCC • How do you re-index • DMV’s • Change Management • Security

  10. Performance • Monitoring • Database Design Creep • Recording your counters • Business measurements • Partitioned Tables\Partitioned Views • Your database to manage your database • Performance Indicators • Drive Space • Index fragmentation • Business counters
