Benchmark summary 18.05.00

The objective of this benchmark is to characterize the performance and scalability aspect of a deployed AR System ITSM stack under various field conditions. For a realistic simulation, the benchmark workload must include both online and batch workloads. For details about the workload, see Definition of performance benchmark use cases.

A supporting environment was built and IT infrastructure was used in this benchmark to depict a typical deployment architecture, such as the HA requirement of many critical deployments.

The workload simulations include the following:

• A mixed workload simulating BMC Remedy ITSM, BMC Service Request Management (SRM) and Reporting users with BMC Atrium CMDB processes running in continuous mode
• A standalone BMC Remedy Single Sign-On workload
• A standalone BMC Atrium CMDB with 1M CIs workload

The supporting lab environment includes the following:

• An F5 load balancer
• The BMC Remedy Mid Tier web application deployed as a cluster on multiple tomcat instances
• Multiple instances (HA) of the Remedy Single Sign-On (RSSO) web application with each instance deployed in the same tomcat as the AR mid tier web application
• Exactly one Remedy Smart Reporting Server
• Exactly 2 AR System servers configured as an AR Server Group

Following are the key takeaways of the benchmark results:

• For the 600 concurrent users mixed (online and batch) workload benchmark, the average end-user response time per use case is comparable to the Remedy 18.05 release.
• The BMC Remedy ITSM suite guideline for hardware sizing is consistent and identical to BMC Remedy ITSM Suite.
• The AR mid tier deployed as a cluster scales horizontally and vertically.
