Problems solved by technology

For example, a host device that jumps from a low load level to a high load level may initially not get the best performance from the storage system as it may take a while for the storage system to ramp up or recalibrate for this higher load
Conventional techniques cannot adequately detect and mitigate these performance degradations

Embodiment Construction

[0018] Illustrative embodiments will be described herein with reference to exemplary information handling systems and associated computers, servers, storage devices, and other processing devices. It should be understood, however, that the embodiments of the present disclosure are not limited to use with the specific illustrative system and device configurations shown. Accordingly, the term "information processing system" as used herein is intended to be interpreted broadly so as to encompass, for example, processing systems including cloud computing and storage systems, as well as other types of processing systems including various combinations of physical and virtual processing resources. Thus, an information handling system may include, for example, at least one data center comprising one or more clouds hosting multiple tenants sharing cloud resources. The term "information handling system" also covers many other types of enterprise and cloud-based computing and storage syst...

Abstract

An apparatus in one embodiment comprises a host device configured to communicate over a network with a storage system comprising a plurality of storage devices. The host device includes a set of input-output queues and a multi-path input-output driver configured to select input-output operations from the set of input-output queues for delivery to the storage system. The multi-path input-output driver is configured to analyze an input-output load pattern of the host device for a predetermined period of time and to categorize the input-output load pattern into one of a plurality of predetermined load pattern categories based at least in part on the analysis. The multi-path input-output driver is configured to transmit information specifying the categorization of the input-output load pattern to the storage system. The storage system is configured to adjust its processing of input-output operations based at least in part on the categorization of the input-output load pattern.

Description

technical field [0001] The field relates generally to information handling systems, and more particularly to storage in information handling systems. Background technique [0002] Storage arrays and other types of storage systems are often shared by multiple host devices over a network. However, problems can arise in such arrangements when input-output (IO) load patterns from the various host devices vary or fluctuate over time, which can lead to degraded storage system performance. In some cases, performance degradation may be related to the storage system not being optimized or calibrated for the particular load pattern exhibited by the host device. For example, a host device that jumps from a low load level to a high load level may initially not get the best performance from the storage system because it may take a while for the storage system to ramp up or recalibrate for this higher load. Conventional techniques cannot adequately detect and mitigate these performance ...
