FIG. 3 is a diagram illustrating an example interaction path between a host device and a logical volume of a storage array using functionality for interfacing applications using kernel space block devices with IO load balancing and submission functionality in the user space in an illustrative embodiment.

FIG. 4 is a flow diagram of an example process for interfacing applications using kernel space block devices with IO load balancing and submission functionality in the user space in an illustrative embodiment.

Illustrative embodiments will be described herein with reference to exemplary information processing systems and associated computers, servers, storage devices and other processing devices. It is to be appreciated, however, that embodiments of the present disclosure are not restricted to use with the particular illustrative system and device configurations shown. Accordingly, the term “information processing system” as used herein is intended to be broadly construed, so as to encompass, for example, processing systems comprising cloud computing and storage systems, as well as other types of processing systems comprising various combinations of physical and virtual processing resources. An information processing system may therefore comprise, for example, at least one data center that includes one or more clouds hosting multiple tenants that share cloud resources. Numerous other types of enterprise and cloud-based computing and storage systems are also encompassed by the term “information processing system” as that term is broadly used herein.
