Prerequisites

You must meet certain prerequisites and collect specific information from your existing VMware vSphere environment in order to proceed with the installation of VMware Greenplum. You may need to work with your system and network administrator to gather some of the information.

Greenplum Cluster

• Ensure that you have determined the number and size of master hosts and segment hosts that you will deploy, based on the Greenplum Database size discussed in the Planning section.
• You must verify that the free space in the datastore, the free memory in the cluster, and total amount of free processors in the cluster are enough to accommodate both the master hosts and segment hosts Sizing requirements that match your configuration.

VMware vSphere

• You must have access to VMware vSphere Client through a VMware vSphere administrator level user that belongs to the Administrators group. In this documentation we use [email protected] with password DeleteMe123!. Refer to the VMware vSphere documentation for more information.

• You must have access to the Internet to download the HCIBench 2.6.0 OVA file for validating Dell EMC VxRail setup performance and a Greenplum Virtual Appliance OVA file for deploying the Greenplum Virtual Appliance.

• Collect the following information from your VMware vSphere environment, you will need it during the installation and setup stages.

  • ESXi hosts IP addresses, host names, admin access name and passwords.
  • VMware vSphere server IP and Fully Qualified Domain Name (FQDN).
  • VMware vSphere datacenter name.
  • VMware vSphere vSAN datastore name.
  • VMware vSphere compute cluster name.

Network

Request the following from your network administrator, you will need it during installation. See Setting Up vSphere Network for more detailed information.

• 4 routable IP addresses in the same network to be used for the external network gp-virtual-external.
• 3 new VLAN IDs. You must also gather information about the existing VLANs in the VMware vSphere environment and how they are interconnected.
• 2 sets of contiguous non-routable IP addresses for the internal networks gp-virtual-internal and gp-virtual-etl-bar. The number of IP addresses per set must be your number of calculated segment hosts plus one for the Greenplum Virtual Appliance virtual machine. For example, for a four-host setup, you will need two sets of 67 IP addresses each: 66 for Greenplum and one for the appliance.
• NTP server and DNS server IP address.

Next Steps

You are now ready to start with the installation and configuration of VMware Greenplum on vSphere. Proceed to Setting Up vSphere Network to start configuring Greenplum on VMware vSphere.
