Chapter 27. Red Hat Gluster Storage
Chapter 27. Red Hat Gluster Storage Red Hat Gluster Storage provides flexible and affordable unstructured data storage for the enterprise. GlusterFS , a key building block of Gluster, is based on a stackable user-space design and aggregates various storage servers over a network and interconnects them into one large parallel network file system. The POSIX-compatible GlusterFS servers, which use the XFS file system format to store data on disks, can be accessed using industry standard access protocols including NFS and CIFS. See the Product Documentation for Red Hat Gluster Storage collection of guides for more information. The glusterfs-server package provides Red Hat Gluster Storage. For detailed information about its installation process, see the Installation Guide for Red Hat Gluster Storage. 27.1.

These processes have advanced process isolation unbounded with the glusterd_t SELinux type.
