2.2. Red Hat Gluster Storage for On-premise Architecture
Red Hat Gluster Storage for On-premise enables enterprises to treat physical storage as a virtualized, scalable, and centrally managed storage pool by using commodity storage hardware.
It supports multi-tenancy by partitioning users or groups into logical volumes on shared storage. It enables users to eliminate, decrease, or manage their dependence on high-cost, monolithic and difficult-to-deploy storage arrays.
You can add capacity in a matter of minutes across a wide variety of workloads without affecting performance. Storage can also be centrally managed across a variety of workloads, thus increasing storage efficiency.
