Abstract
Methods and systems are presented for allocating resources based on dynamic core allocation in a scheduler hierarchy of a storage system. One method includes reserving a set of core processors including one or more core processors for execution of system IOs in the data storage system. The data storage system includes a controller including non-volatile memory (NVRAM) for handling IOs and a first central processing unit (CPU) having a plurality of core processors, a solid state memory (SSD) configured as a read cache memory, and permanent data storage. The method includes dynamically adjusting the number of core processors in the set based on a current utilization of a resource. The method includes scheduling an IO on a first core processor of the plurality of core processors that has the least magnitude of scheduled utilization.
