RexRay

Overview

RexRay is a cross-platform storage introspection application that is meant to provide visibility and management of external/underlying storage that is attached via methods specified in drivers. This storage can be from a specific storage platform in addition to being provided by virtual infrastructure.

The driver to be used is automatically detected or hints can be provided. Drivers are then intialized to retrieve guest identifiers and further information from other platforms that are relevant to storage management.
