What is the minimum number of cores needed to run Portworx?

The official Portworx Enterprise documentation specifies the minimum hardware requirements for running a production-grade cluster. For the central processing unit (CPU), a minimum of 4 cores is recommended. This ensures that the node has sufficient computational resources to handle the Portworx services, which manage I/O, data replication, snapshots, and other storage operations, alongside the containerized applications and the Kubernetes agent (kubelet). While Portworx might run on fewer cores in a non-production or test environment, 4 cores is the established baseline for a stable and supported production deployment.

A. 16: This is a recommendation for a high-performance node, significantly exceeding the minimum requirement for a standard production environment.

B. 8: While 8 cores are a common and good recommendation for nodes with heavier workloads, it is not the documented minimum.
