Abstract
A technique for handling storage commands includes receiving, by an interface node of a data storage system, a first storage command. The interface node determines whether the first storage command is a head of queue (HOQ) command. In response to determining the first storage command is an HOQ command, the interface node increments a constrained command count and issues the first storage command to a first worker processor core for processing. In response to determining the first storage command is not an HOQ command, the interface node processes the first storage command as a non-HOQ command.
