Hardware requirements

This section lists the minimum hardware requirements.

Your minimum hardware requirements are determined by the needs of the components of your specific Netcool Operations Insight solution.

OCP hardware requirements:

If you are installing IBM Common Services as part of an Agile Service Manager deployment on RedHat OpenShift Container Platform (OCP), you must add an additional 32 Gb of RAM to the worker node on which IBM Common Services is to be installed.

On-prem hardware requirements:

For its on-prem edition, the Agile Service Manager core components are deployed to a single server and the following physical or virtual hardware requirements must be met.

Specifically, a number of Kernel parameters must be configured to optimize Cassandra and ElasticSearch, which run better when Swap is either disabled or the Kernel vm.swappiness parameter is set to 1 (in the sysctl.conf file). This setting reduces the Kernel's tendency to swap and should not lead to swapping under normal circumstances, while still allowing the whole system to swap under emergency conditions. See the following topic in the reference section for an example of a sysctl.conf file: Example sysctl.conf file

Requirement Setting Notes
CPU 32 cores

Recommendation

You may need to increase the number of cores to 48 for heavy workloads, where an expected event input rate of 50 events per second (or more) is expected, and large numbers of resources (one million or more) are being managed.

Memory 64 GB  
Disk 500 GB

Recommendations

Use disk arrays with redundancy, such as RAID10, with a minimum of 1000 IOPS.

One disk mount of at least 500 GB is needed at the $ASM_HOME/data directory. During installation, Agile Service Manager works with this mount point and creates the following required folders:
  • $ASM_HOME/data/cassandra
  • $ASM_HOME/data/elasticsearch (OCP only)
  • $ASM_HOME/data/postgres (on-prem only)
  • $ASM_HOME/data/kafka
  • $ASM_HOME/data/zookeeper
