Abstract:
1. A method for simulating write pacing, comprising: receiving input corresponding to at least one of: a configuration and a workload of a data storage system; receiving input corresponding to an event on the data storage system; receiving input corresponding to write pacing parameters of the data storage system; simulating processing of the data storage system that is required in connection with the event on the data storage system; and determining processing characteristics of a write pacing operation according to the write pacing parameters during the simulated processing of the data storage system during the event, wherein the data storage system includes a first storage device and a second storage device and wherein the first storage device replicates data to the second storage device asynchronously and wherein the write pacing operation includes controlling a write response time between when a write request is received and when the write request is acknowledged by the first storage device, and wherein the write response time is controlled according to the write pacing parameters.
