File system operations for a storage supporting a plurality of submission queues

Abstract

A computational device configures a storage system that supports a plurality of submission queues. A file system monitors characteristics of received writes to distribute the writes among the plurality of submission queues. The computational device categorizes the writes into full track writes, medium track writes, and small track writes, measures a frequency of different categories of writes determined based on the categorization of the writes, and generates arbitrations of the writes with varying priorities for distributing the writes for processing in the submission queues. A full track write includes writing incoming data blocks of the writes received to a fresh track, in response to a total size of the incoming data blocks being equal to or more than a size of one full track. A medium track write includes overwriting an existing data track. A small track write includes staging the incoming data blocks to a caching storage.
