The server hardware used in this reference architecture are Hewlett Packard Enterprise (HPE) rack mounted servers, specifically the HPE ProLiant DL360 Gen9 and HPE ProLiant DL380 Gen9 models. The network switches used in this reference architecture are HPE FlexFabric switches, the HPE FF 5930 and HPE FF 5700. The following section provides an overview of the technical specifications for the servers and network equipment used in this reference architecture.

The servers and networking components are shown below in Figure 1. There are two top of rack switches, an HPE FF 5700 and an HPE FF 5930, the HPE FF 5700 is used for management (iLO) and provisioning, and the HPE FF 5930 is used for OpenStack networking including; internal API, external, storage, storage management, and tenant communications. There are eleven rack mounted servers shown in Figure 1; one Red Hat OpenStack Platform director, three Red Hat OpenStack Platform controllers, four Red Hat OpenStack Platform compute nodes, and three Red Hat Ceph Storage nodes.
