Quantifying utilization of a data storage system by a virtual storage unit

摘要

The contributions of a virtual storage unit to the utilization of a data storage system may be quantified. A utilization score may be determined for each virtual storage unit for one or more functional components of the data storage system, for example, a front-end adapter, back-end adapter or interface physical storage unit. A utilization score may be determined for the data storage system as a whole by combining the component utilization scores of the virtual storage unit. Component and/or system utilization scores may be visually presented to a user in a manner that enables the user to assess the relative contributions of the virtual storage units to utilization of the component or overall system, respectively. What-if scenarios may be considered using the utilization scores to determine the consequences of moving one or more virtual storage units from one data storage system to another, and a live migration may result.

1. For a plurality of virtual storage units of a data storage system comprising a plurality of functional components, including at least one of: a front-end adapter and a physical storage unit interface, a method comprising:
for a first of the plurality of virtual storage units:
determining a first front-end adapter utilization value of a first front-end adapter that quantifies a utilization of the first front-end adapter by the first virtual storage unit;determining a first physical storage unit interface utilization value that quantifies a utilization of a first physical storage unit interface by the first virtual storage unit; andcombining at least the first front-end adapter utilization value and the first physical storage unit interface utilization value to produce a first overall system utilization value of the first virtual storage unit; and for a second of the plurality of virtual storage units:
determining a second front-end adapter utilization value of at least a second front-end adapter that quantifies a utilization of the at least second front-end adapter by the second virtual storage unit;determining a second physical storage unit interface utilization value that quantifies a utilization of at least a second physical storage unit interface by the second virtual storage unit; and combining at least the second front-end adapter utilization value and the second physical storage unit interface utilization value to produce a second overall system utilization value of the second virtual storage unit.
