# Solution Components
This solution describes the deployment of the HPE Ezmeral Container Platform, the creation of a Kubernetes cluster with the native HPE Ezmeral Data Fabric for Kubernetes, and an app modernization use case using KubeDirector. HPE Ezmeral Container Platform Controllers, Gateway servers, and Kubernetes cluster nodes are configured to achieve high availability. The HPE Container Storage integration CSI driver gets installed in an automated fashion as a part of the cluster installation. This section outlines the hardware, software, and service components utilized in this solution.
# Solution Physical Components
# Hardware
The HPE Ezmeral Container Platform environment is built around HPE ProLiant DL Gen10 Plus Servers using a deployment setup consisting of Nineteen(19) HPE ProLiant DL Gen10 Plus Servers: three (3) HPE ProLiant DL325 Gen10 Plus Servers are deployed as HPE Ezmeral Container Platform Controllers in a highly available configuration, two (2) HPE ProLiant DL325 Gen10 Plus Servers are deployed as gateway Load Balancer server, three (3) HPE ProLiant DL325 Gen10 Plus Servers as Kubernetes storage cluster master along with five (5) HPE ProLiant DL385 Gen10 Plus Servers for the Kubernetes storage cluster worker nodes that are used to create the HPE Ezmeral Data Fabric for Kubernetes and finally six (6) HPE ProLiant DL325 Gen10 Plus Servers are deployed as Kubernetes compute cluster worker nodes and master nodes. Local Disks on the servers are used for providing storage for Ephemeral Disks and Persistent Volume in Kubernetes Clusters.
The persistent volume from the HPE Ezmeral Data Fabric for Kubernetes is configured for the Kubernetes compute cluster by deploying an HPE CSI driver.
Figure 6 shows the physical layout of the server, storage, and network used for the solution.

# Disk requirement
A minimum of two (2) raw disks of 500GB or higher in addition to the OS disk is required. Minimum one (1) 500GB raw disk is for Docker storage (ephemeral storage). These disks are provided by as local disk.
The operating system installation and prerequisites for the deployment are automated as part of this solution. The playbooks to deploy operating systems and the prerequisites are available at, https://github.com/HewlettPackard/hpe-solutions-hpecp.
# Software
# Operating System installation
Installs the SUSE Linux Enterprise Server 15 SP2 and ensures that the system has appropriate licensing in place using SUSE subscription. Installs the latest patches using zypper and ensures that the prerequisites have been met for each server.
The operating system installation and prerequisites for the deployment are automated as part of this solution. More details can be found further in the document under OS deployment section.
Table 2 describes the software versions utilized in the creation of this solution. The installation user should ensure that they download or have access to this software. Ensure that the appropriate subscription and licensing are in place to use within the planned time frame.
