Solution Admin Host deployment

  • This section gives the detail about SAH node and the infrastructure VMs deployment.

    Pre-requisites

    If you do not have a management node present in your environment, complete the following pre-requisites: 

    • Dell EMC PowerEdge server with latest firmware and BIOS versions with minimum one Intel 64-bit x86 processor.
    • Minimum 32 GB memory and 500 GB disk space.
    • Minimum 4 NICs (10 GbE minimum, 25 GbE preferred) used for management, provisioning the overcloud and PowerFlex data traffic.
    • Configure the switches as required, based on the network considerations, see Network planning.

    Install and configure

    • Install RHV 4.4 as a self-hosted engine or standalone Manager. For the complete deployment instruction, see Installing Red Hat Virtualization. 
    • For a HA enabled RHV cluster shared storage is a requirement, for this solution NFS is used as a shared storage.
    • Configure the networking as explained in Network planning to run multiple infrastructure VMs.

    Note:  For a production deployment, Dell EMC recommends configuring HA for SAH node and any mission critical VMs.

    Create infrastructure VMs

    Below infrastructure VMs were deployed using RHVM:

    • DNS server 
    • PowerFlex Gateway 
    • Undercloud 
    • NTP server 
    • PowerFlex presentation server
    • Overcloud controller

    DNS server 

    Domain Name System is used for name resolution on both the undercloud and overcloud. A Fully Qualified Domain Name (FQDN) is required to install and configure undercloud VM. 

    1. Deploy an RHEL VM on the SAH node with minimal installation and configure the network. 
    1. Install the DNS package and configure the forward and reverse lookup zone files. 

    NTP 

    A Network Time Protocol server is used to synchronize time. For a HA cluster deployment, it is essential that controllers are synchronized to a single time source. Configure NTP in DNS VM or install and configure NTP in a new VM with minimal configuration.  

    Undercloud 

    As already mentioned in the OpenStack components part of this document, the undercloud or director node is used to deploy, control, and monitor the overcloud. In this solution, the undercloud is deployed as VM. RHOSP overcloud section provides prerequisites and deployment guide for Director (undercloud) installation.

    PowerFlex Gateway 

    The PowerFlex Installation Manager is installed as part of the PowerFlex deployment. The PowerFlex Gateway also includes the REST gateway and SNMP trap sender functionality. The PowerFlex Gateway is installed as a VM on the SAH node.

    For PowerFlex Gateway installation, see Install PowerFlex Gateway on Linux.

    Note: In this paper, the terms PowerFlex Installation Manager and PowerFlex Gateway are synonymous.

    PowerFlex presentation server

    Install PowerFlex presentation server as a VM on SAH node. From PowerFlex 3.5 version onwards, a PowerFlex Presentation Server is used rather than the Java based client software.

    For more details, see Install the PowerFlex presentation server.

    Overcloud controller 

    Three overcloud controller VMs are deployed on the SAH nodes. These VMs are not deployed with an operating system as this will be done as part of the overcloud deployment process. RHOSP overcloud section provides prerequisites and deployment guide for Overcloud deployment.
