You can watch the replay for this Geek Sync webcast in the IDERA Resource Center: http://ow.ly/UK1s50A5osi Before you go to bed at night, do you worry about a tempdb blowing up a thin-provisioned LUN? In this session we cover the most common elements in your environment that will cause you to lose sleep. This slide deck covers how to locate the current and future bottlenecks in your environment, as well as what capacity constraints are at greatest risk of impacting your uptime.

3. Why Bother?
Everything is running great – and nothing
ever changes…

4. Why Bother?
Capacity Constraints Impact
• Unplanned Downtime
• Internal User Experience
• Budget Overruns / Unplanned Expense
• Operational Efficiency
• Peace of Mind

5. Points of Constraint
Common Areas of Focus (Network)
• WAN Circuits
• Access Layer Uplinks
• QoS Buckets
• VPN Sessions
• CPU
• Memory

6. Points of Constraint
Common Areas of Focus (Systems)
• Storage (IOPs)
• Storage (Capacity)
• Storage (Latency)
• Storage (everything else)
• CPU
• Memory

7. Capacity Planning Methods
Manual Analysis is Hard
• Infrastructure Changes
• Shifting Demand / Growth Events
• Data Overload
• Demand Cycles
• Time
• Blended Workloads

8. Capacity Planning Methods
Common Data Sources (Network)
• SNMP-derived If / CPU / Memory
• Netflow / NBAR
• IPSLA
• Topology Map

9. Capacity Planning Methods
Common Data Sources (Systems)
• SNMP/WMI derived If / CPU / Memory / Storage
• vCenter
• Storage Arrays
• Dependency Map
• SSRS

10. Capacity Planning Methods
Statistical Analysis
• Modeling (Current + Future Known Load)
• Trending (Future reflects past)
• Forecasting (Current + Unknown Future)
• Workload Impact (How does workload impact
constraints?)

11. Capacity Planning Methods
Statistical Analysis
• Static / Normalized Datasets
• ToD / DoW
• Linear Regression
• Peak Load

12. Remediation Strategies
Anticipatory
• Use Modeling / Forecasting to pre-purchase
• Least risk of service interruption
• Greatest risk of financial waste
• Particularly with resources defined by step-
functions
• Most time consuming

13. Remediation Strategies
Reactive
• Use current load baseline(s)
• May derate constraints / Use thresholds
• Greatest risk of service interruption
• Least risk of financial waste

14. Remediation Tactics
Network
• Buy More! Buy Bigger!
• Implement QoS / Policing
• WAN Op is still a thing
• CDN / Edge Caching
• AWS Direct Connect

15. Remediation Tactics
Systems
• Buy More! Buy Bigger!
• Thin Provisioning
• Address VM Sprawl
• Storage Tiering
• Cold / Offline Storage
• Hybrid Cloud Adoption – Capex vs. Opex

16. Remediation Best Practices
• Document Process and Assumptions
• Pick Consistent Data
• Run Multiple Models (Best/Worst/Avg)
• Reconcile Outcomes with Expectation
