Abstract:
An apparatus comprises at least one processing device. The at least one processing device is configured, for each of a plurality of logical storage devices of a storage system, to determine in a multi-path layer of a layered software stack of a host device a performance level for that logical storage device, to communicate the performance levels for respective ones of the logical storage devices from the multi-path layer of the layered software stack of the host device to at least one additional layer of the software stack above the multi-path layer, and to select particular ones of the logical storage devices for assignment to particular storage roles in the additional layer based at least in part on the communicated performance levels. The additional layer in some embodiments comprises an application layer configured to automatically select a particular one of the logical storage devices for a particular storage role.
