Dynamic routing of data responsive to hardware component failures

A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing device causes the at least one processing device:

• to identify, for a modular server comprising a chassis, a plurality of hardware components installed in the chassis, wherein the plurality of hardware components comprise at least a first input-output module and a second input-output module, and a first expander and a second expander of a storage system installed in the chassis, wherein the first input-output module is connected to the second input-output module and the first expander, wherein the second input-output module is connected to the first input-output module and the second expander, wherein the first expander is connected to the second expander and the first input-output module, and wherein the second expander is connected to the first expander and the second input-output module;
• to determine a failure of one of the first input-output module and the second input-output module, and to determine a failure of one of the first expander and the second expander;
• and
• to dynamically route data through respective ones of the plurality of hardware components which remain operational in response to the determined failures;
• wherein the at least one processing device is connected to the first input-output module, the second input-output module, the first expander and the second expander.

A method comprising:

• identifying, for a modular server comprising a chassis, a plurality of hardware components installed in the chassis, wherein the plurality of hardware components comprise at least a first input-output module and a second input-output module, and a first expander and a second expander of a storage system installed in the chassis, wherein the first input-output module is connected to the second input-output module and the first expander, wherein the second input-output module is connected to the first input-output module and the second expander, wherein the first expander is connected to the second expander and the first input-output module, and wherein the second expander is connected to the first expander and the second input-output module;
• determining a failure of one of the first input-output module and the second input-output module, and determining a failure of one of the first expander and the second expander;
• and
• dynamically routing data through respective ones of the plurality of hardware components which remain operational in response to the determined failures;
• wherein the method is performed by at least one processing device comprising a processor coupled to a memory;
• and
• wherein the at least one processing device is connected to the first input-output module, the second input-output module, the first expander and the second expander.
