that are added to an existing building block do not require an extra POWER9 EMS node. A single POWER9
EMS node can support multiple building blocks in the same IBM Elastic Storage System 3200 cluster.
You need a minimum of one POWER9 EMS node as a part of your ESS cluster. The POWER9 EMS node
can be ordered as a part of IBM Elastic Storage System 3200. When IBM Elastic Storage System 3200 is
added to an existing ESS cluster that has a POWER9 EMS node, the same POWER9 EMS node can also be
used to manage IBM Elastic Storage System 3200.
IBM Elastic Storage System 3200 is supported only on the POWER9 EMS. The minimum release level on
the IBM Elastic Storage System 3200 canisters is ESS 6.1.1.
For more information about the POWER9 EMS node, see Model 5105-22E server specifications.
The EMS node also serves as a third IBM Spectrum Scale quorum node in a configuration with one
building block.
System management
An EMS node in an IBM Elastic Storage System 3200 cluster provides system management functions.
IBM Elastic Storage System 3200 GUI runs on the EMS nodes and provides management and health
monitoring capabilities. The EMS node also runs a container with Ansible playbook that can provide
orchestration of complex tasks, such as cluster configuration, file system creation, and code update. The
following figure shows high-level view of system management topology.
