IT asset management in data centers is one of the most complex scenarios in ITAM: environments with high density of physical servers, virtual machines, storage systems, and high-performance networks require precise inventory, specific licensing control, and SAM processes adapted to the rules of the main vendors — especially IBM, Microsoft, and Oracle, whose data center licensing models differ significantly from standard corporate environments.
Why data centers require specialized asset management.
Data center asset management goes beyond simply having a good inventory tool. To succeed, a SAM program in a data center environment requires a solid foundation built on three pillars: people (defined roles and responsibilities), processes (policies, flows and success criteria) and platform (tool integrated into the environment).
Visibility alone doesn't solve the problem. Without structured processes, organizations cannot sustain the level of technological maturity required for a data center environment—especially in dense virtualization and multi-cloud scenarios.
Microsoft licensing in data centers: the SPLA agreement
Service providers that host Microsoft applications for third parties use the SPLA (Service Provider License Agreement), a monthly licensing model based on reported usage. The main features of the SPLA are:
- Monthly licensing per subscribing users or per processor.
- Mandatory monthly usage report to Microsoft via authorized reseller.
- It covers products such as Windows Server, SQL Server, Exchange, SharePoint, and others.
- It requires precise tracking of users and hosted environments.
IBM and PVU licensing in data centers
IBM licensing by PVU (Processor Value Unit) is one of the most complex in datacenter environments. Each processor type has a different PVU value, and IBM requires the use of ILMT (IBM License Metric Tool) for any organization that wants to take advantage of sub-capacity licensing—that is, licensing only the processors actually used by the VM, and not the entire server.
Without ILMT installed, configured, and updated quarterly, IBM may require full-capacity licensing for all servers in the environment, regardless of how many processors the IBM workloads actually utilize. In environments with dozens of servers, the difference between sub-capacity and full-capacity can represent millions of dollars in additional licenses. ServiceNow SAM Pro natively integrates with ILMT and HCL BigFix Inventory via APIs, automating PVU data collection and ensuring that IBM compliance reports are always up-to-date.
Specific challenges of asset management in data centers
| Challenge | Impact |
|---|---|
| Dense virtualization (VMware, Hyper-V) | IBM and Oracle licensing rules do not recognize soft partitioning — risk of underbilling. |
| Multi-cloud (AWS, Azure, GCP) | Licensing metrics differ between on-premises and public cloud. |
| High turnover of VMs | Assets created and destroyed quickly make manual tracking difficult. |
| Tier-1 editors focused | IBM, Microsoft, Oracle, and VMware account for up to 80% of software spending in data centers. |
| Infrastructure as a Service (SPLA) | Monthly reporting requires automation of usage data collection. |
Cost and performance optimization in data centers.
Cloud-based solutions like IBM Turbonomic help data center managers optimize infrastructure performance and cost by connecting performance data with resource allocation decisions. The combination of advanced management tools, efficient processes, and a skilled team ensures availability, performance, and security while optimizing costs and energy consumption.
