Requirements for HPE Ezmeral Data Fabric on Kubernetes (for non-production environments only)

Describes the requirements for HPE Ezmeral Data Fabric on Kubernetes, which is only supported for non-production environments. For all production requirements, recommendation is to use HPE Ezmeral Data Fabric on Bare Metal.

There are two types of configurations of HPE Ezmeral Data Fabric on Kubernetes:

Recommended Configuration

Beginning HPE Ezmeral Runtime Enterprise 5.5.0, recommendation is to use HPE Ezmeral Data Fabric on Bare Metal for use in production environments.

Footprint-Optimized Configuration

Footprint-optimized configurations implement HPE Ezmeral Data Fabric on Kubernetes on a smaller set of nodes. Footprint-optimized configurations are intended for non-production environments, such as development, testing, and proof-of-concept demonstrations. Footprint-optimized configurations are not supported on production environments.

For information about the different footprint-optimized configurations for non-production environments, see Requirements for HPE Ezmeral Data Fabric on Kubernetes — Footprint-Optimized Configurations.
