This topic describes the Greenplum Database 6 platform and operating system software requirements.

Parent topic: Installing and Upgrading Greenplum

Operating Systems

Greenplum Database 6 runs on the following operating system platforms:

  • Red Hat Enterprise Linux 64-bit 8.7 or later
  • Oracle Linux 64-bit 8, using the Red Hat Compatible Kernel (RHCK)
  • Rocky Linux 8

A kernel issue in Red Hat Enterprise Linux 8.5 and 8.6 can cause I/O freezes and synchronization problems with XFS filesystems. This issue is fixed in RHEL 8.7. See RHEL8: xfs_buf deadlock between inode deletion and block allocation.

Note Do not install anti-virus software on Greenplum Database hosts as the software might cause extra CPU and IO load that interferes with Greenplum Database operations.

Greenplum Database server supports TLS version 1.2 on RHEL/CentOS systems, and TLS version 1.3 on Ubuntu systems.

Software Dependencies

Greenplum Database 7 requires the following software packages on RHEL systems. The packages are installed automatically as dependencies when you install the Greenplum RPM package):

  • apr
  • apr-util
  • bash
  • bzip2
  • curl
  • krb5
  • libcurl
  • libevent
  • libxml2
  • libyaml
  • zlib
  • openldap
  • openssh-client
  • openssl
  • openssl-libs (RHEL7/Centos7)
  • perl
  • readline
  • rsync
  • R
  • sed (used by gpinitsystem)
  • tar
  • zip

VMware Greenplum Database 7 client software requires these operating system packages:

  • apr
  • apr-util
  • libyaml
  • libevent

Greenplum Database 7 uses Python 2.7.12, which is included with the product installation (and not installed as a package dependency).


SSL is supported only on the Greenplum Database coordinator host system. It cannot be used on the segment host systems.

For all Greenplum Database host systems, if SELinux is enabled in Enforcing mode then the Greenplum process and users can operate successfully in the default Unconfined context. If increased confinement is required, then you must configure SELinux contexts, policies, and domains based on your security requirements, and test your configuration to ensure there is no functionality or performance impact to Greenplum Database. Similarly, you should either deactivate or configure firewall software as needed to allow communication between Greenplum hosts. See Deactivate or Configure SELinux.


Greenplum Databased 7 supports these Java versions for PL/Java and PXF:

  • Open JDK 8 or Open JDK 11, available from AdoptOpenJDK
  • Oracle JDK 8 or Oracle JDK 11

Hardware and Network

The following table lists minimum recommended specifications for hardware servers intended to support Greenplum Database on Linux systems in a production environment. All host servers in your Greenplum Database system must have the same hardware and software configuration. Greenplum also provides hardware build guides for its certified hardware platforms. Work with a Greenplum Systems Engineer to review your anticipated environment to ensure an appropriate hardware configuration for Greenplum Database.

Minimum Hardware Requirements
Minimum CPU Any x86_64 compatible CPU
Minimum Memory 16 GB RAM per server
Disk Space Requirements
  • 150MB per host for Greenplum installation
  • Approximately 300MB per segment instance for metadata
  • Cap disk capacity at 70% full to accommodate temporary files and prevent performance degradation
Network Requirements 10 Gigabit Ethernet within the array

NIC bonding is recommended when multiple interfaces are present

Greenplum Database can use either IPV4 or IPV6 protocols.


Resource Groups - one of the key Greenplum Database features - can control transaction concurrency, CPU and memory resources, workload isolation, and dynamic bursting.

When using resource groups to control resource allocation on Intel based systems, consider switching off Hyper-Threading (HT) in the server BIOS (for Intel cores the default is ON). Switching off HT might cause a small throughput reduction (less than 15%), but can achieve greater isolation between resource groups, and higher query performance with lower concurrency workloads.

VMware Greenplum on DCA Systems

You must run VMware Greenplum version 6.9 or later on Dell EMC DCA systems, with software version and later.


The only file system supported for running Greenplum Database is the XFS file system. All other file systems are explicitly not supported by VMware.

Greenplum Database is supported on network or shared storage if the shared storage is presented as a block device to the servers running Greenplum Database and the XFS file system is mounted on the block device. Network file systems are not supported. When using network or shared storage, Greenplum Database mirroring must be used in the same way as with local storage, and no modifications may be made to the mirroring scheme or the recovery scheme of the segments.

Other features of the shared storage such as de-duplication and/or replication are not directly supported by Greenplum Database, but may be used with support of the storage vendor as long as they do not interfere with the expected operation of Greenplum Database at the discretion of VMware.

Greenplum Database can be deployed to virtualized systems only if the storage is presented as block devices and the XFS file system is mounted for the storage of the segment directories.

Greenplum Database is supported on Amazon Web Services (AWS) servers using either Amazon instance store (Amazon uses the volume names ephemeral[0-23]) or Amazon Elastic Block Store (Amazon EBS) storage. If using Amazon EBS storage the storage should be RAID of Amazon EBS volumes and mounted with the XFS file system for it to be a supported configuration.

Data Domain Boost (VMware Greenplum)

VMware Greenplum 6 supports Data Domain Boost for backup on Red Hat Enterprise Linux. This table lists the versions of Data Domain Boost SDK and DDOS supported by VMware Greenplum 6.

VMware Greenplum Data Domain Boost DDOS
6.x 3.3 6.1 (all versions), 6.0 (all versions)

In addition to the DDOS versions listed in the previous table, VMware Greenplum supports all minor patch releases (fourth digit releases) later than the certified version.

VMware Greenplum Tools and Extensions Compatibility

Client Tools

VMware releases a Clients tool package on various platforms that can be used to access Greenplum Database from a client system. The Greenplum 7 Clients tool package is supported on the following platforms:

  • Red Hat Enterprise Linux x86_64 8.x (RHEL 8)
  • Oracle Linux 64-bit 8, using the Red Hat Compatible Kernel (RHCK)
