The Logical Storage Layer

Space contentions in the VNX system have to be avoided at all costs to ensure peak performance and continuous availability of and uninterrupted access to critical storage resources. For this, you can use the tests mapped to the Logical Storage layer. These tests monitor the space usage of the file systems, storage pools, LUNs, disk volumes, and meta volumes, and promptly point administrators to those entities that have or are about to run out of space. In the process, the tests also monitor how quickly the disk/meta volumes and LUNs process I/O requests and warns administrators of potential processing slowdowns.
