5 RHCF Proof of Concept Configuration

Customers often have different requirements and standards when it comes to what can be

deployed. This proof of concept provides one combination of the hardware and software

versions that were tested in the Red Hat Reference Architecture labs. This section provides

an overview of the software and hardware required to build a Red Hat Cloud Foundations

solution.

As shown in Figure 5.1: Infrastructure Overview, there are two clusters configured. The first

cluster is a cloud services infrastructure management cluster set up with Red Hat Cluster

High Availability running on Red Hat Enterprise Linux version 6.0 hosted on two IBM

BladeCenter

servers. Attached is an HP MSA fibre channel storage array that presents a

single 500GB LUN to both servers. This shared storage enables the virtual machines to be

stored on the SAN and failed over to the other node in the event of a host failure or scheduled

maintenance. This cluster hosts the virtual machines that provide management and

infrastructure services like Satellite server, DNS, DHCP, PXE, JBoss Operations Network and

MRG Manager.

The second cluster is running Red Hat Enterprise Virtualization with one host using a Red Hat

Enterprise Virtualization Hypervisor and the other host running Red Hat Enterprise Linux with

KVM – both are on IBM BladeCenter servers. The HP MSA fibre channel storage array is also

presenting a single 500GB LUN to these two hosts which enables fail-over of the virtual

machines. This cluster is responsible for hosting the virtual machines that run the

applications which scale out. These applications are a Seam based hotel reservation system

running on JBoss Enterprise Application Platform, a custom Java application called javaApp

and finally a perfect number application running on MRG grid execution nodes.
