Abstract
A computer-implemented method to reduce Input/Output (I/O) command latency. The method includes receiving, by a first storage pool, a plurality of I/O commands, wherein the first storage pool includes a first throttling limit, and the first throttling limit. The method further includes determining a first processing rate of the first storage pool is at the first throttling limit. The method also includes determining a second processing rate of a second storage pool is below a second throttling limit, wherein the second storage pool is communicatively coupled to the first storage pool. The method includes sending, by the first storage pool to the second storage pool, one or more of the plurality of I/O commands. The method further includes processing, by the second storage pool, the one or more I/O commands of the plurality of I/O commands. The method includes returning processed I/O commands to the host.
