| Abstract: |
Applying a rate limit across a plurality of storage systems, including: determining a rate limit for paired storage systems; receiving, by a first storage system, an amount of I/O operations serviced by the second storage system during a previous predetermined period of time; determining whether the amount of I/O operations serviced by the second storage system is less than half of the rate limit for the paired storage systems; if so, setting local a rate limit for a next predetermined period of time for the first storage system to the difference between the rate limit for the paired storage systems and the amount of I/O operations serviced by the second storage system during the previous predetermined period of time; and otherwise, setting a local rate limit for a next predetermined period of time for the first storage system to half of the rate limit for the paired storage systems. |
