The Storage Processor Layer
Using the tests mapped to this layer, administrators can focus on the overall operational state and operational efficiency of their storage processors and storage ports. This way, they can quickly identify disabled storage processors/ports, proactively detect a potential overload condition and/or an I/O processing bottleneck with storage processors / ports, and initiate measures to resolve these issues. In addition, the layer also throws light on storage processor cache usage and data mover cache usage to enable administrators to figure out whether a bad user experience with the storage processor can be attributed to an improperly sized cache.
