Methods and systems for managing service level objectives in a networked storage environment

Abstract:

Methods and systems for a networked storage system are provided. One method includes determining by a processor, a demand pattern for a first workload that is assigned a service level objective (SLO) for using a resource of a networked storage system. The SLO is defined by an allotted performance parameter, and the demand pattern identifies a first duration when a SLO allotment for the first workload is underutilized, and a second duration when the SLO allotment is being utilized. The SLO allotment is dynamically adjusted for the first duration by modifying a parameter associated with the performance parameter, while maintaining the SLO allotment for the second duration. This makes additional performance capacity of the resource available for re-allocation. The additional available performance capacity is dynamically allocated for an identified second workload that needs an increase in SLO allotment for a certain duration and/or for provisioning a new workload.
