Hardware requirements and recommendations
Review the minimum CPU, Memory, RAM, and Disk space requirements for setting up and running IBM® Cloud private clusters.
The following tables list the minimum system requirements for running IBM® Cloud private in both evaluation and production environments.
System requirements vary depending on whether you want to set up a multi-node cluster, or set up a test environment by using a single host. A single host environment has boot, master, worker, and proxy nodes all running on a single host.
|Number of hosts||1|
|Cores used||2 or more|
|CPU power||>= 2.4 GHz|
|RAM||4 GB or more||You need more than this minimum amount of memory, if you plan to run applications in this test cluster that might use a substantial amount of memory.|
|Disk space to install||40 GB|
|Requirement||Boot node||Master node||Proxy node||Worker node||Notes|
|Number of hosts||1||1, 3 or 5||1, 3 or 5||1 or more|
|Cores used||1 or more||2||1 or more||1 or more||Choose a modern processor with multiple cores. Common clusters use 2 - 8 core machines. When it comes to choosing between faster CPUs or more cores, it is recommended to choose hosts with more cores.|
|CPU power||>= 2.4 GHz||>= 2.4 GHz||>= 2.4 GHz||>= 2.4 GHz|
|RAM||4 GB||8 GB||4 GB||4 GB|
|Disk space to install||40 GB||40 GB||40 GB||40 GB|
Note: Elasticsearch is the database that is used to store monitoring, performance metrics, and logs for containers. The recommended disk space to meet the needs of elasticsearch is 30 GB. The path for the elasticsearch data is
Ensure that enough disk space is available for this data path on each master node.
