Tips:

• Carefully review the IBM License Information Document (LID) for your specific IBM software.
• Be aware of changes. IBM often updates licensing metrics that could impact compliance.
• Consult Internal Teams: Always communicate with your IT and procurement teams to fully understand the impact of each licensing model.

2. Inventory Assessment

The first step in capacity planning is to assess your current inventory.

• Create a Comprehensive Software Inventory: Track the software in use, including version, license type, and licensing metric. This is essential for both compliance and cost estimation.
• Hardware and Virtual Machine Assessment: Assess the hardware where IBM software runs, whether physical or virtual. Accurate inventory helps assess requirements correctly.
• Understand Software Interdependencies: Know which software requires specific versions of hardware or other applications.

Techniques:

• Gather real-time data using automated inventory tools such as IBM License Metric Tool (ILMT) or Flexera FlexNet Manager.
• Cross-Check Manual and Automated Data: Even with automation, perform manual checks to ensure the completeness of your inventory.

3. Use IBM License Metric Tool (ILMT)

IBM License Metric Tool (ILMT) is the preferred tool for tracking product license usage using the PVU or RVU model. IBM even requires ILMT for certain products to ensure compliance with sub-capacity licensing rules.

Benefits of ILMT:

• Accurate Usage Data: ILMT tracks usage data regularly to ensure you use your licenses correctly.
• Audit Preparation: ILMT data helps you prepare for IBM audits by providing an easy-to-understand usage summary.
• Automated Updates: The tool automatically updates IBM’s PVU tables, ensuring accurate license calculations.

Best Practice:

• Schedule ILMT scans monthly to have up-to-date data for audits or capacity review.
• Training: Ensure your IT team is well-trained on ILMT functionalities to get the most value from the tool.

4. Analyze Historical Usage Trends

Analyzing past trends helps predict future needs. Historical data provides insight into usage peaks, user behaviors, and seasonal variations.

Approach:

• Collect Historical Data: Look at the last 6-12 months to understand usage patterns.
• Identify Peak Times: Identify when usage spikes occur. This could be during end-of-year reporting or other peak activities for your organization.
• Seasonal Adjustments: Plan for extra license capacity when high demand is likely.
• Utilize Data Visualization Tools: Use tools like Power BI or Tableau to visualize historical data for better understanding.

Examples:

• A retail company may notice higher IBM license usage during holiday seasons due to increased customer activity.
• A financial institution might see spikes in workload at the end of each quarter, corresponding with reporting requirements.

5. Align License Requirements With Business Objectives

Every organization should match license capacity planning with business needs.

Steps:

• Identify Key Business Units: Determine which teams or departments rely heavily on IBM software and evaluate their growth prospects.
• Communicate with Stakeholders: Consult department leaders on projected growth, hiring plans, and initiatives that could change software demand.
• Future Growth Consideration: Plan capacity for cloud migration, big data analysis, or digital transformation projects.
• Understand Department-Specific Usage: Different teams use IBM software differently. Align licenses to ensure availability without unnecessary overlap.

Example:

• If the marketing team plans to launch new digital campaigns, check if additional IBM software is required for data analytics.
• When expanding into new regions, ensure that license plans can accommodate the projected increase in operations.

6. Utilize Forecasting Tools for Accuracy

Forecasting is essential for accurate license planning. Multiple tools and techniques are available to assist with license forecasting.

Popular Tools for IBM License Capacity Forecasting:

• Flexera One: Provides complete visibility into software usage and forecasts future licensing needs.
• ServiceNow: Integrates asset management and license tracking with organizational change projects.
• Snow License Manager: Uses historical data to predict future usage accurately.
• Dynatrace: Offers insights into resource usage and supports capacity planning through monitoring and AI analysis.

Techniques:

• Regression Analysis: Historical license usage is used to identify trends and estimate future requirements.

7. License Pooling and License Sharing

License Pooling allows flexibility in a dynamic organization where software use may change from department to department. With the right pooling strategy, you can improve efficiency by reducing unused licenses.

Steps to Achieve License Pooling:

• Identify Commonly Used Software: Identify IBM software that is common across multiple departments.
• Create a Shared Pool: Maintain shared licenses rather than allocating individual licenses to every department.
• Monitor Pool Usage Regularly: Review license pools to ensure the allocation matches actual needs.

Benefits:

• Cost Savings: Reduces the total number of licenses required.
• Increased Efficiency: Optimizes licenses across the organization to maximize usage.
• Flexible Scaling: Allows departments to scale up or down based on specific project demands.

Example:

• A company might establish a license pool for data analytics tools like IBM Cognos, which the finance and marketing teams use at different times of the year.

8. Regular Compliance and Audit Reviews

Compliance issues with IBM can result in costly penalties. Conduct regular compliance reviews to prevent unexpected compliance issues.

Checklist for Compliance Reviews:

• Quarterly Compliance Reviews: Schedule at least quarterly checks to identify gaps.
• Software Usage Monitoring: Monitor users and metrics that exceed allowed usage.
• Audit Preparation: Maintain records of ILMT reports and other documentation required for IBM audits.
• Documenting License Changes: Keep a clear record of all changes to licensing metrics and adjustments in license allocation.

Examples:

• An organization using WebSphere had discrepancies between purchased licenses and usage. Regular reviews allowed them to adjust usage before an audit, saving penalties.
• A healthcare provider reviewed their compliance with IBM Watson, adjusting allocations to match their data processing needs during pandemic spikes.

9. Monitor Virtualized Environments Closely

If your IBM software runs in a virtual environment, tracking licenses can become complex, especially with dynamic resource allocation.

Tips for Managing Virtual Environments:

• Track Resource Allocation: Closely monitor allocated CPUs, as licensing might depend on each application’s virtual CPUs (vCPUs).
• Use ILMT for Virtual Environments: ILMT provides sub-capacity support, enabling effective license tracking even in cloud and hybrid setups.
• Define Licensing Boundaries: Clearly outline boundaries for clusters, hypervisors, and physical servers to prevent licensing miscalculations.
• Cluster Resource Limits: Ensure that resource limits are clearly defined for each cluster to prevent potential breaches of license agreements.

Example:

• Virtual machines are commonly added and removed depending on workload needs. Use VM tagging to keep track of software installed on virtual environments and ensure that each VM complies with licensing agreements.

10. Plan for Sub-Capacity Licensing

IBM allows sub-capacity licensing, which means you can license only a part of your server resources (e.g., only some cores on a multi-core server). If managed well, this can save money.

Considerations for Sub-Capacity Licensing:

• Understand Eligibility: Only certain products are eligible for sub-capacity. Confirm eligibility through the Passport Advantage program.
• Sub-Capacity Reporting: Report sub-capacity data correctly using ILMT, as IBM requires.
• Verify with IBM: If you are unsure about sub-capacity licensing requirements, consult with IBM or an IBM Licensing Partner.
• Monitor Hardware Changes: Hardware upgrades or changes can affect sub-capacity licensing calculations. Stay on top of these to avoid compliance issues.

Example:

• An organization accidentally exceeded the number of licensed cores after a server upgrade. Implementing a system to verify licensing after hardware changes could have avoided this.

11. Automate Where Possible

Automation can significantly reduce errors and enhance the accuracy of license tracking.

Tools for Automation:

• IBM ILMT Automation: Automate ILMT scans and updates to reduce human error.
• RPA (Robotic Process Automation): RPA repeats tasks such as data entry and verifying license compliance.
• APIs for License Data Integration: Use APIs to integrate data from multiple sources and tools, reducing the need for manual data reconciliation.

Benefits:

• Accuracy: Automation reduces the risk of miscounting licenses.
• Efficiency: Frees up time for IT teams to focus on more strategic activities.
• Consistency: Automated scripts run consistently without the risk of human fatigue or oversight.

Example:

• Automating ILMT updates with cron jobs can save IT administrators hours on manual updates and ensure no scans are missed.
