Abstract

The disclosed technology can be used to develop systems and perform methods that receive and process I/O requests directed to at least a part of a logical unit of storage. The I/O requests can be associated with different times corresponding to when such I/O requests were received. Nodes that include non-overlapping address ranges associated with the logical unit of storage can be formed in response to receiving the I/O requests and such nodes can be subsequently organized into a tree data structure. The tree data structure can serve as a basis for determining address overlap, for example to enable processing a first operation associated with a first one of the I/O requests in accordance with the first I/O request's receipt time, while one or more other operations associated with a different I/O request may be processed irrespective of that different I/O request's receipt time. This can be useful in a system in system operations are improved by easy access to information about whether pending I/O requests are directed to overlapping units of storage.
