Variables that affect performance and scalability

The performance of a BMC TrueSight Infrastructure Management Server depends on several variables, and the performance and scalability guidelines and recommendations address these. Substantial changes in any of the following variables can change the expected scaling and performance numbers:

  • Total number of monitor instances. A Monitored Instance is the equivalent of the NT_CPU BMC PATROL application class.
  • Total number of attributes. An attribute in Infrastructure Management corresponds to the CPUutilisation parameter in BMC PATROL.
  • Service model content, including the following considerations:
    • Number of service models
    • Number of configuration items (CIs) per service model
    • Depth of a service model
  • Types of monitored devices
  • Number of key performance indicators (KPIs)
  • Retention period of data and events
  • Number of adapters and monitors on each Integration Service
  • Polling frequency
  • Number of concurrent users
  • Number of external events per day
  • Number of alarms and abnormalities per day
  • Disk I/O of the database server
  • Network bandwidth utilization
  • Hardware configuration, including the number of CPUs, amount of memory, and storage technology (such as SAN or RAID)
Warning

Do not use 32-bit hardware to deploy a BMC TrueSight Infrastructure Management Server. No performance or scalability testing is performed on 32-bit hardware. If you are using 32-bit hardware and want to upgrade to version 9.6 of Infrastructure Management, upgrade to 64-bit hardware before upgrading the Infrastructure Management software.

Note

Adapters for Microsoft System Center Operations Manager (SCOM), BMC Transaction Management Application Response Time (TM ART), and BMC Portal were not tested for scalability in Infrastructure Management 9.6.
