Chapter 1. Introduction to Red Hat Gluster Storage for Virtualization

Red Hat Gluster Storage can be configured as a storage domain for Red Hat Virtualization, allowing you to store virtual machine images on Red Hat Gluster Storage instead of in network-attached storage appliances or a storage area network array.
This guide shows you how to configure Red Hat Gluster Storage as a Red Hat Virtualization storage domain in a traditional, non-hyperconverged configuration.
This configuration consists of Red Hat Virtualization hosts, and Red Hat Gluster Storage servers, as illustrated in Figure 1.1, “Architecture of integrated Red Hat Virtualization and Red Hat Gluster Storage”.

Important

Red Hat Virtualization 3.3 onwards includes the GlusterFS storage domain to enable future support for the libgfapi protocol. The GlusterFS storage domain uses the same access mechanism as the POSIXFS domain.
