The present embodiments relate to throttling input/output (IO) processing tasks at a centralized node (e.g., a SmartNIC device) and implement multiple routing paths to prevent performance degradation in handling data patterns. For instance, the centralized node can implement a throttling system to assign portions of a number of input/output operations to be performed to a series of extent servers in a cloud infrastructure environment. The present embodiments also can implement multiple paths and/or multiple path groups to route the assigned portions of the I/O operations. For instance, the assigned portions of I/O operations can be routed to the extent servers via a first path of multiple paths. In the event of a failure of the first path, the assigned portions of I/O operations can be re-directed to a second path or another path in the path group.
