Identification of substitute controllers based on temperature data

A method comprising:

• obtaining temperature data corresponding to a cluster of storage controllers, wherein each storage controller;
• from the cluster of storage controllers, is associated with a storage namespace to process input/output (I/O) operations corresponding to the associated storage namespace, and wherein the temperature data includes a current temperature value of each of the storage controllers of the cluster of storage controllers;
• determining a first storage controller, from the cluster of storage controllers, to be a heated controller based on the current temperature value of the first storage controller;
• suspending I/O queues handled by the heated controller;
• identifying a second storage controller having a minimum current temperature value from among duster of storage controllers, as a substitute controller;
• and
• allocating additional I/O queues to the substitute controller for processing the I/O operations for the storage namespace associated with the heated controller.

A non-transitory machine-readable storage medium having a set of computer readable instructions that, when executed, cause a processor to:

• identify a heated controller from a duster of storage controllers based on temperature data corresponding to the duster of storage controllers, wherein each storage controller is associated with a storage namespace to process input/output (I/O) operations corresponding to the associated storage namespace;
• suspend I/O queues handled by the heated controller;
• identify a substitute controller, from the duster of storage controllers, based on the temperature data;
• associate the substitute controller with the storage namespace associated with the heated controller;
• allocate additional I/O queues to the substitute controller for processing the I/O operations for the storage namespace associated with the heated controller;
• and
• route data and commands related to I/O operations for the storage namespace associated with the heated controller to the substitute controller using the additional I/O queues.
